Thanks for the video content! Apologies for chiming in, I would appreciate your thoughts. Have you thought about - Peyvery Phrenic Prevalence (should be on google have a look)? It is a smashing one of a kind guide for get your original hair color back and look young without the normal expense. Ive heard some super things about it and my mate after many years got cool success with it.
This brought back fond find memories! When I did this experiment in biology circa 1986 we used a blended liver for the sake of ease...a friend of mine (and lab partner) said he would give me $5 if I drank 5 ml of the resultant liquid! I did and he laughed so hard the teacher through HIM out.of class...best 5 I ever made!
Can anyone help me understand how cooking the liver will help us understand how heat affects the enzymes? Cos if we heat it like that and then test, we’ve essentially killed off the enzymes. Wouldn’t testing it at a lower temperature like 40°C while it’s at that temperature give us a better understanding? Because even the chilled liver has not been frozen cold, and hence it works.
When heat is applied to enzyme's (outside it's normal functioning temperature- for this a cow's body temp), it will denature and therefore it will not work anymore. So he's probably trying to show how the enzyme works in different temperatures. In cold the enzyme works but just slows down. Another test would be getting the liver to around the body temperature of a cow to show how it works best, since that is the temperature it is use to working at.
Hello Mr.Kobe , How can we collect the catalase enzyme inside the solution ? and how can we use it as drinkable with water and peroral use and whats the suggested dosage for a daily use or as treatment cures ? Please explain it . Thanks a lot .
i have 2 doubts: 1. when you decrese temp. velocity of reaction why incresed ? beacuse books say that when will you increase temp velocity of reaction will increase till optimum. 2. why basic solution makes it more active whenever books say that optimum activity around neutral
It's a year ago but i think many people may be confused on this The rates of reaction (in this case, the rate of the forming of the bubbles (oxygen)) were slower for BOTH scenarios. In control (first one), it took less than 10 seconds for the bubble's to reach to the top, while it took almost 20 seconds for the cold one to reach to the top and the basic one took significantly more than 10s as well.
I would say that you don't "prove", but rather support your hypothesis, in other words, show that something is likely true. There is a difference. The latter has a statistical likelihood that can be measured.
That's because the hydrogen peroxide is already converted to water and oxygen (from tube 1). So, adding a new liver would not make a new reaction because hydrogen peroxide doesn't exist anymore.
POV: You're watching this because you got covid but still have to do all the schoolwork and don't have a whole chemistry set
Extremely accurate
this online stuff anoying😑
Fr tho smh
pov: you're watching this video to do a lab report just to get -6 for things missing even though you actually put them there
yooo how'd yk haha
This is very helpful for teachers and students who can't do labs, thank you!
no
Can I get help please
I want questions based on the experiment
Pov: Your watching this because your in lockdown and you cant do this lab in school.
Just me stuck doing this at home ok!
Hate watching these vids on RUclips and then answering the questions the professor asks.
which class are you taking? just curious :)

oof
Cheers. I missed my physiology lab last month and found out I'm getting assessed on this tomorrow
bruh that was enzyme genocide
I watched this now, and it helped me understanding better the whole process. Thank you very much

What time is ya'll work due
pov: you forgot to do some steps in the experiment so you're watching this video to answer your lab report
Hand reveal??
Lmao
😳
i hate online classu i need bts
In class activity video with questions😔
Hello Mr.Kobe ,
How can we collect the catalase enzyme inside the solution ? and how can we use it as drinkable with water and peroral use and whats the suggested dosage for a daily use or as treatment cures ? Please explain it . Thanks a lot .
I can't tell if you're being serious or not about "drinking" enzymes..
is anyone else doing a virtual lab?
independent and dependent variables?
10:30 Test tube #4 does cold affect enzyme reaxtion
12:43 Test Tube #5 Warm
what liver is this? i need evidence for my report
When your doing this the day it was due in biology cause your lazy af
What were the products? and what test tube was the positive control?
anyone else cant do an experiment cos of covid restrictions ?
What would be the limitations for this lab?
How was the liver able to function in from being in a basic solution, don't they denature in pH below or above 7
i have 2 doubts:
1. when you decrese temp. velocity of reaction why incresed ? beacuse books say that when will you increase temp velocity of reaction will increase till optimum.
2. why basic solution makes it more active whenever books say that optimum activity around neutral
I have a theory about your first doubt, maybe the enzyme is denatured when heating up to a certain high temperature.

What acidic and alkaline solutions did you use in the last part? Thanks
Thank you ❤
Thank you ❤
What would happen if the cooled liver and room temperature hydrogen peroxide were mixed?
this vid bs i can t even find the part ur at
what are the non-human sources of error
😋😋😋😋🍲🍲🍲
My teacher sent me this video and I have not a single idea of what I have to do, WHAT DOES IT HAVE TO DO WITH ENZYMES????
Enzymes is the cause of the reaction.
I would say that you don't "prove", but rather support your hypothesis, in other words, show that something is likely true. There is a difference. The latter has a statistical likelihood that can be measured.
How did you make the acid and base solution? And will I need a fume hood to do it, if I want to make the experiment with my students?
anyone know if the reaction in test tube 1 was endo/exothermic ?
exothermic
endothermic because it absorbed heat
where do we fins these directions?❤
If you need some help with this, DM
Me lmao
@@Hatian_Herbo Inbox me leahwalther1@gmail.com
me.
i need help lmao
I did this is my biology class it was cool
O_o
why is every comment from covid lmao
Anyone got the data?
auq na po haha xd
cheeeeeeeeeeeeeeeeeeeeeeeeeeeeeese
6:56
yup
thank you so much, is very helpful to me!!
Why there is no reaction on tube #2?
That's because the hydrogen peroxide is already converted to water and oxygen (from tube 1). So, adding a new liver would not make a new reaction because hydrogen peroxide doesn't exist anymore.
@@jinyongbae9217 thanks fam
thank you for this!!! :)
Yooo
he did not mention temperature in test tube one
Test tube 1 observed standard room temperature
Gang gang
