Praktikum enzim katalase

approximately hirohmanirohim Assalamualaikum

warahmatullahi wabarakatuh Yes this time

we will conduct a catalase enzyme test

yes because the tools and materials

are the first main ingredient

is this liver I brought chicken liver yes

but this chicken I have not continued or

I have not destroyed yes then the

other ingredients are the main ones that

we will describe with mulane surrender H2O

2 yes then there is another Happiness what is

this HCL yes to make the atmosphere

acidic mood is the media

Sam yes then the next is

this NaOH yes NaOH is a

chemical compound that will later make the

mood become a language whose pH is

above 7 Metland then we will

introduce the tools which are

only there are

10 strong test tubes yes then this is a test tube rack

then there are clamps yes

test tube clamps then there is a mortar and pestle

this is the bus for

taking care of yes to wrap the liver then

you only Next what is this

spirit lamp yes in the spirit lamp then

here I have a small explanation yes

then I also have a rather large one

yes like this Well I filled it with

water Tayal also has a dub stick

Hi video so this is its function

to test yes because after it has

become embers then we use it

to lock the activity of the

catalase enzyme yes from the gas that is formed

then I also have an iPad

This iPad is quite a lot why this Club nature

must be used one by one for the ingredients

yes do not mix to use it

So if this type is used to

take a cellphone it should not be used

to take another Faham then

what else yes This is this test tube

especially the prophet for what to

clean the goat after it has lost

its activity then I also have features and

information that are clean yes then this

look at my hands I have used

gloves yes the same as the infusion

what to protect my skin from

irritation what

hi first by peroxide compounds or

H2O 2 then I also have a

data balloon orange white yes what is

this balloon for later we will try me what is it

called we try to make a ever

asked an exciting experiment yes in the

context of August 17 Okay we will

immediately start preparing the ingredients

first we will what grind

or crush the liver yes by

using what is using a

mortar and pestle Okay Smart friends

we will immediately start to

crush the chicken liver yes later father

want it like this yes There are several logins

yes Well you can pay attention remember when

studying in grade 11 we will try to

destroy his heart So actually

Why do we have to destroy the liver

why does it have to be crushed like that

or is there a purpose the purpose is

so that the catalase enzyme contained

in the liver in the liver cells

will come out when it is going to come out in

the way it was destroyed if not destroy it

How can it be or not yes

later you can prove it we will

destroy it like this yes Yes until I am

serious yes this until Well after you

can add water yes I have

prepared here just plain water here we

continue we put it in

Hi father Okay book friends yes

we already have liver extract yes

this is the one below here is his liver

so tomorrow yes later we will

just take the extract we take we put it

in five test tubes yes

each one is about 1 choose

yes when 01 cm yes approximately one is

called this yes we put it in hi hi hi hi yo

wes big approximately 1 cm high we

make it into five you yes welcome

our guests prepare

hi next

Hi now this is already done five you

yes already finished five years later

Next what's next is

we have to prepare a peroxide solution

or H2O 2 Dad what is

this lt22i water why is it put

in a brown bottle who knows

yes that's right So why should it be

put in a brown bottle

because this compound is easily decomposed by

fine light the color is brown or

dark then we will prepare five

test tubes that we fill with

peroxide solution or H2O 2 approximately

1 cm high which is the same as the

liver extract earlier Okay kids we

will try our democracy for

catalase enzyme testing Well

we have prepared all the ingredients

Now we will try to

demonstrate it well

this I will light a match first

yes yes

ih but in fact eat yes already

spirit lamp like this yes see yes

change

hi okay now when I'm done I will

pour this liver extract into

my H2 well I will hold it using

tongs yes use tongs so that yes It's delicious

Yes this is

liver extract this H2O sermon we will try it

we customers like this I slide

first yes I pour What will

happen Please pay attention I Hi like

this What happened

oh yes what happened we have there is money or

there are bubbles the pressure is just right

from the bottom yes it is strong

if it is food don't hold it too

long later we will open the tip of our thumb

Well we will test with ridhomu barat

we have prepared the media we want

our goods to open like this yes not more

lit yes but Lidya mobarak we

put it in here what will happen

Pay attention yes Want to happen in di

become a lit map we try to close it again

is there still an enzyme reaction to

break down H2O 2 yes we will try we

still need yes this is burrow barat

we put it in again is it more

lively this becomes lit we

see yes yes it turns out it still means there is still

not ready to form yes like that is

it

later you will find out the answer

yes then the next is

Hi extract of the liver ship that has been

added with acid yes in the liver

it becomes acid

Hi armpit there what is it like we try to

crash here

Hi will happen

Hi are there bubbles no yes no

if there are none We test again

with Lidya burning whether is the

burning stick becomes lit Pay attention

yes this is more burning we

put it in here Yes it turns out it turns out it was

more than before smoldering to extinguished

yes okay We recorded the third experiment that is

unique Allah this is

Hi liver extract that has been added

with NaOH yes so The atmosphere becomes

wet we go home here he said it

becomes the change

Hi there is no good If there is none we

check with a burning stick again yes is

there a flame or not yes

we turn this off first yes

Hi there is no yes but this is there is

a little bit of wobbly fat yes but earlier there was

no flame so you

can later Satya You haven't a little

Hi like this but there is no flame it

doesn't go out immediately yes don't

plant it like the treatment we

see our HCL yes then the

fourth well this fourth

Hi HP extract we Heat it first

Hi choice pay attention I am

heating the liver the liver so it is hot yes

we Heat it at the end of the fire yes

until it boils so it feels like

when it

boils it makes a crackling sound yes this

It seems we Heat it don't let it

squirt out yes Well if we have this liver

land plot Yes we have Heat it

then we will pour this liver

with H2O 2 so this H2O 2 or if

this H2O 2 is poured with the front of

its name What does a heated cell phone look like? Are

there bubbles? Please

pay attention

here.

Hi, there are bubbles.

Hi, there are no bubbles. It means

200k if there are no bubbles, which

means there is no reaction at

the end. Why is the sensitivity going to experience

denaturation? Enzyme damage due to

heating? Try checking with the number of

broken items. There is a flame. We enter the variable here.

Hi, it turns out it doesn't light up, dear. The

last one is the cooled liver.

After we will test the next

one, the

test tube containing the cooled liver. Yes, we

take it from the

refrigerator. Yes, this is cold. Then

we will treat it like before, namely

pouring h2t Smart pouring the

liver extract containing the catalase enzyme.

Yes, we see two pieces. I hold them

with my left hand. No, it is

a cooled liver.

We will try to pour it here. Is

there a change in the bubbles?

Let's close it like this. Then

we prepare the burning seeds. We

will test it. Is the mask inserted here

lit? It turns out it is lit. Yes,

if the temperature is still what is still

possible? The optimum temperature then the enzyme

is still working, yes, like that. Well, we

ask, have you practiced

testing the catalase enzyme with several

treatments, namely, the first is the

liver extract, left alone, the second

is added with HCL, the third is

added with NaOH. The fourth is

heated and the last is cooled

which we have seen together, yes, the

results of the reaction What is it like and you

can prepare and draw conclusions, yes,

that there is an influence, yes,

Environmental factors that affect the work of the enzyme

from catalase, namely the degree of acidity factor,

pH, and the second is the

temperature factor, yes, later you can read again

the theories about enzymes or the influence of

environmental factors on the

activity of the enzyme catalase, it's time to

play, yes, we will pour the

Israeli liver extract later, now the foam is this

Islamic liver extract, the remaining liver From the results of

our experiment, then there are

only two watermelons, but the relationship is

only the setup here, other tamberlains,

No, then now we will make money,

right? Is this liver extract into

this Erlenmeyer, yes, yes,

big, we will, Sir, come here, yes,

using liver extract, then we

close it, yes, there it is, yes, choose what will

happen, then the second one is also

return the liver extract here, yes, we

close it with a balloon, it's like this What

will happen to our balloon

Oh yes, more Oh yes,

Hi, what happened, Oh yes, it

turns out the balloon was blown up by

this case, yes, firmly, is that it, Oh, this is

for you, the bottom is leaking, this is why it

can't expand, yes, Hi, the

heart is leaking, your ideals the

other one yeah we hurry this person finished

e

Hi Ho Hi

hey There was a leak earlier

Hi me this has been inflated to

Oh okay my children all

this time the practicum is finished This

is the result of our play yes this is a

balloon that can be inflated because earlier

we have put peroxide water and the

rest of Nadia's liver extract to be able to

inflate the balloon well of course

in this balloon there was gas yes

right dashop Siger earlier after we

praised him with Lidya burning it turned out that

the media defending earlier became lit

meaning we are sure that the gas that was

formed was oxygen Happy

birthday

Hi Republic of Indonesia 75th
