I seriously think you should get a Nobel Prize, you've changed education forever

I literally didn't even finish watching the Report. I went over to the site thinking this whole online academy was a neat idea, and started finding videos about the topics I need to study for my test next week (pity I only found out about the Academy today). It's 1:56am and I'm studying Biology on the web for free. THIS is what those visionaries imagined the Internet would be one day.

I love this! This is such an amazing explanation. I've always struggled to understand these concepts and I have ADHD so it's especially difficult for me. But I love this teacher! I plan to watch every video I can! I just can't thank you enough! It's really going to help me with my future career plans. I haven't watched any videos with other teachers yet, so I can't say how well the others do at explaining things, but if I were a teacher I would want to be this good. And if I ever make enough money to do so, I will donate to this organization.

Thank you so much for taking the time to make these videos. I am taking an EMT course and have been memorizing all the information so I can pass the test but never really understanding how it works and after watching these videos it is all starting to make sense ^.^

You help so much. I'm studying sports medicine and this is exactly what I needed !!

Super helpful video! I sat down to watch the cellular respiration series thinking that I would be cramming for my cell bio exam tomorrow but it turns out that I already knew the stuff,, i just needed a simple and clear expaination and this was it! I don't think many professors know how helpful it is (especially to adhd students like myselft) to just explain things in the simplest terms and expressions. I just love how concise and exact your lessons are. I know it can be good practice to have to use critical thinking skills to reach conclusions about topics like this but i find that style of teaching to be my weakness. anyways thanks a bunch for these great videos! If i wasn't a broke college student i would surely provide a great donation!

You, sir, have always been a life saver! Thank you so much for everything ❤️

Studying & learning for 'visual learners' has become so much better with mainstream internet use and great videos like this. Thanks for simplifying something which is initially quite confusing:)

It took me like ten different videos but I think I'm finally understanding this!

God bless this man even though I still dont get it

Thank you so much for making these videos!!!They'll help me a lot!!!

Thank you! I love how you use the colors . You wrote so clearly. Makes it so much better!

Super nice video, clear, structured and very organized.Thanks for your input.

I find that watching videos like this is the happy medium of learning. (So is teaching in a class while writing on the board, if the teacher does it well, i think.) Reading from a textbook is energy-draining and difficult. Listening to a lecture can be boring and you can miss details. But listening *and* reading, looking at the notes and listening to the explanation, is like reading along to an audiobook; it makes a lot of sense, and doesn’t require that much strain or cause confusion. Thank you for all the help. I hope you know you’re a *literal blessing* to us all

this is an honest question...can someone please tell me when i will ever need this, unless i become a biologist

Sal, watching your Biology videos saves me a lot time and I actually understand all these subjects better. I'm sure I'll do good in my Biology finals tomorrow because of you. (:

wow..

Wow, thank you so much. You helped answered many of my questions!!

This professor is the best!!!! I hate online classes but I would rather take his online class than in person because he is just THAT GOOD!

I love how simplified this is... Makes me feel smart (even though Biology is my worst subject)

Thank you for taking the time to actually explain this in a calm manner unlike crashcoarse that just rushes through everything. After this video, I have a better understanding of cellular respiration!

I think you are amazing! The way you break things down to their most simplistic forms then go on from makes cellular respiration much easier to comprehend, thank you.

Doesn't it produce 36 ATP?

@kabtastick

9 жыл бұрын

No 38

@rileyb5987

9 жыл бұрын

38 ATP is how many ATP that is produced in the entire process from 1 glucose, but there are multiple steps that require ATP and only produce ATP under ideal conditions so the NET ATP is closer to 30 ATP. It is calculated as cytosol NADH (NADHc)=1.5 ATP (as it costs an ATP to enter the mitochondria) mitochondria NADH (NADHm)=2.5 ATP GTP=1 ATP FADH2=1.5ATP Glucose = 2ATP+2GTP+2NADHc+8NADHm+2FADH2 = 30 ATP (text books say 36 because they round all the .5 ATPs up and 38 because they dont account for the invested 2ATP.)

@gertrudechikwanka4370

8 жыл бұрын

+叶靖宇 one molecule of glucose will produce 38 mol of ATP if the NADH produced is transported to the mitochondria via the malate shuttle but if it is transported to the mitochondria via the glycerophosphate shuttle, only 2 mol of ATP will be formed so the net production will be 36 instead of 38

@qwertyokful

8 жыл бұрын

+叶靖宇 Without the Krebs cycle it would produce only 36 but combing the process of the Electron transport chain and the Krebs cycle it creates a total a 38.

On school tests (EOCs) it says it gives 36 instead of 38 so teachers say it's 36 instead of 38

If the video is nice and watchable then it is obvious it will have maximum viewers and the uploader get to earn money and the students who are hungry for knowledge gets to lear many new and interesting things.

this is excellent. One of the best videos on youtube. Thorough, precise, and enough detailed information to not only give us the main idea, but not too many stupid little fragments. Thank you so much. My honors bio teacher is 80 years old and doesn't have a clue what he is doing.

I've understood everything this semester except respiration and this has been a really good review to help clarify before exams. Subscribe!

This video has been very helpful, i will continue to watch the videos that relate to my A level work. I give credit to the educator that derived this information Thumbs up to him. Thanks for posting these video's x

i love your videos! they help me a lot!!! teachers don't care about explainig all these little details that make all the difference understanding such an interesting thing that students think it's boring (because of the way regular teachers teach these...)

this is actually so pretty to look at ! thanks ! I have a test tmro and I learn visually.

Understand the basic understanding of Enzymes for catalyzing the chemical reactions of life 2. Watch the amoeba sisters on this topic 3. Then come back to this video and everything makes sense 😂😂😂
