Thank you Professor Revell, this was highly valuable information.

You're a goober

@@invisafish97 Thank you Professor Revell, this was highly valuable information.

[@fmjjjjn7510]

The text book was filled with way too many big words and numbers and didn’t understand. Thanks for this, now I understand it more.

[@janinescheifele5335]

would you mind sharing what text book this experiment was mentioned in?

[@ProfessorRevell]

This is a classic experiment we have used for years and years. We use our recipe from our own book we wrote "Life All Around Us" (Bio 1 lab manual)

[@cyanpeoples1721]

You just saved my grade on my lab report. Thank you!

[@ProfessorRevell]

Excellent!

[@Nardiumms]

This is awesome. Simple. Detailed. Structured

[@ceilidhhubbard8992]

Thank you, you saved my bio grades.

[@glacy.brooks5102]

I really needed this, thank you

[@abridgedchris2346]

Had an experiment to do and needed help, thanks

[@abbaschokr7032]

hi professor i wanted to ask what is the independent and dependent variable in this experiment

[@themanifester7755]

I wanted to do this but i am using cup. I was just wondering how many mi-liter of hydrogen peroxide you used in the video?

[@ErinHall-v3z]

which concertation of peroxide is best for this?

[@grsbiosciences]

Dear professor could you help me to know the activity using colorimetric method and caluculation

[@keaganevans9779]

can someone please tell me the independant variable, dependant variable and constant of the investigation is?

[@AaronGoleh]

What is the introduction of this expirment

[@blueandbanana]

Hi Professor Revell, do potatoes or ridge gourd have more catalase? Which fruit or vegetable has the most catalase? What is the best way to extract and preserve catalase?

[@ProfessorRevell]

Good questions. Not sure. Potatoes are the classic example always used. Potatoes are actually a type of modified STEM (not a root). I'd start by investigating the experiment with root structures like carrots or yams. Not sure how one would preserve catalase. You could try freezing a potato for few days and then see if the experiment still works. Maybe I'll try that and upload it here.

[@justtiffany5553]

what is the objective of this lab?

[@ProfessorRevell]

To demonstrate factors affecting enzyme activity

[@adrianbucknor8167]

What amount of hydrogen peroxide did u use??

[@ProfessorRevell]

3%

[@dearselene1513]

I love this thank u so much sir!!! You're the best!!!

[@leojaxxon3405]

I know I'm kinda randomly asking but do anyone know of a good site to stream new series online ?

@Leo Jaxxon flixportal :P

@Elijah Angelo thank you, I signed up and it seems like a nice service :) I appreciate it!

[@elijahangelo5256]

@Leo Jaxxon you are welcome :D

[@ProfessorRevell]

You're very welcome!

[@ianmcheng991]

Does it have to be a type of specefic potato?

thank you, really helpful video

[@vincieborde7923]

Very informative ☺️

[@marwa5279]

What is in tubes 1 and 3

[@Mol2412w3]

very clear and informative

[@ProfessorRevell]

Thanks!!

[@atharvagangan1777]

very informative

[@ProfessorRevell]

Glad you think so!

[@betsytapia8308]

What could this experiment be improved?

[@ProfessorRevell]

you tell me.

[@B_1_L_O]

@@ProfessorRevell can u tell us ?? Cuz im not shur i und !!

[@dearselene1513]

So which potato sample decomposes the most hydrogen?

[@ProfessorRevell]

See my comment above

[@ashwanikumaranyvideo3913]

Sir can we use this formula

[@ProfessorRevell]

I don't see a formula

[@rajkumarsharma6798]

What is the name of engyme?

[@ProfessorRevell]

Catalase

[@AnabolicFaith]

Would it work with Amylase?

[@AnabolicFaith]

And how did you make the enzyme solution?

[@harolddeleon9851]

WHY DID YOU PUT WATER

[@ProfessorRevell]

Good question. Mainly so that all the tubes started at the same volume.

[@sanjayyadav-oz5rk]

Good evening everyone please suggest me everyone how pratical i can conduct form fresh potato tuber.. Like enzymatic activities and which nutrients are present in fresh potato. Like that.. Suggest me .. Those people are conducting all ready please suggest me

[@KingSheep23]

Sorry bro good video but spelt knife wrong

[@rektralf9867]

Does the teacher reads comments

[@ProfessorRevell]

I do. Sample with the chopped up potato releases the most oxygen (product) in the same time period.

[@margretmulenga8734]

Explain the induced fit model of enzyme action, and how this differs from the "Lock & Key" model. Help me with this question sir

[@kalyesubulaleonard]

good

[@kunoa1875]

What is the amount of hydrogen peroxide in each tube?

[@ProfessorRevell]

3%

[@edwardhernandez9156]

Chew your food kids

[@bentzol447]

I like the video, but my teacher wants us to watch this. So it's a dislike for me. Sorry...

[@ProfessorRevell]

Sorry about that. I use this video (and made this video) as a review for students; so we do the experiment together in class and then they can use this video as a review after they have done the experiment.

[@bentzol447]

@@ProfessorRevell That is actually great! I wish my teacher would have the same passion.
P.S.: I didn't dislike the video. I really enjoyed it!!!
