to be honest, its nice that there is an online learning resource that explains things better than my university made textbook and professors combined

[krattgirl]

I've been legit crying because my biology teacher makes this all so confusing. Thank you for explaining it easier

[Στέφανος-λξ]

thank u very very much this helped me a lot to get a bigger picture of it all

[inamri]

OMG! THANK YOU SO MUCH! I have a report tomorrow about enzymes and i already watched and read the concept again and again but i still dont get it. Thanks to ur very simple yet substantial explanation! :)

[aufa]

i hate the backlight. but the voice is so good and clear. thanks 😊 this video really help me alot

[ApekshaGA]

This video is amazing and you guys rock!!

[nyawirawaithaka]

Thanks for these great videos on enzymes.

[uditadas]

really so hlpful one of the best tutorial video ever

[rohanroy]

dat hill diagram explanation got it all👌👌👌

[sarbanisinha]

Awesome man u just u made this concept so easy thankuuuu sooo much may god bless u my dear!!!

[catylver]

Cramming for my Ap bio unit 3 test 😍

(I barely remember this stuff)

[Tejano._.]

Wow the clearest explanation to ever exist thank you 🤍

Not to be technical, but I agree with abopfred. The mountain will probably contain rocks, minerals, and harmful gases that could make going through it very difficult and possibly fatal.

[hiothezebra]

moving a mountain w/ a spade sounds like it would take more energy than just climbing it tbh

[jaccbien]

i could not finish this video just because of that smudged portion of the hill @3:38

[sloanedemelo]

I'm just saying, I'd much rather walk up a hill then dig through it. I understand the concept but damn can't you give me a power tool or something lmao

this is way better than the textbook made by mu professor

[oppozhanmirzahmetov]

Is that graph incorrect for Ea? I can`t see or feel that any extra activation energy was served for a catalase enzyme when it reacts with hydrogen peroxide, I`m convinced that it just happens by itself? Same with an amylase enzyme, you just mix the starch with saliva, and you get starch split into disaccharides.

[jennymarkova]

does anyone know how to explain the Concept of activation energy?

Is this for college or high school level students?
