This is sucha a great video that brings a clear concept about Redox happening in respiration. i learnt in 20 minutes more than what i learnt reading books for 2 hours. superb video. Thank you for posting.....please keep posting more videos .
5:55 I am confused, and correct me if I'm wrong, but does that carbon (image from Wikipedia) need to have an H attached to it? Because the two oxygens require a double bond, that would use up all of carbon's four possible bonds...attaching a hydrogen would give it 5 bonds (impossible)..?
your videos are very helpful, for not only are you giving your viewers a lecture but are also giving visuals. Unlike in class lectures, we are able to go back or pause the video if we did not understand something or missed what you said. I hope you will continue doing this.
CARL SAGAN - "Almost no one attempts to educate themselves on the basics of science and technology, yet our society is based on these. TV takes up far too much of our time and is apparently much more attractive to most of us than the beauty and wonder of science. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces." - CARL SAGAN
Carbon electronegativity: 2.5, Hydrogen electronegativity: 2.2. This isn't a very big difference, but he makes it seem like carbon and hydrogen have this huge electronegativity difference. C-H bonds are not very polar (hence hydrocarbons are very nonpolar), so neither C nor H really "hogs" the electrons. I know that he probably says this to help, but I don't want inaccurate chemistry to be disseminated!
@Hirgum lol woooow! nitpick much? i'd understand if his calculations were completely incorrect, but you're seriously going to harp over a term? and actually, a lot of professors use the term "hog" in introductory courses because they just want the students to learn basic, and core concepts. the actual quantitative net charges of molecular bonds is covered in advanced biochemistry courses, not intro. using the word "hog" just helps students visualize the concept of electronegativity.
thanx so much for the videos, they helped alot, u teach it better than my teachers, they can't explain it, even in tutorials..-.- I might not actually fail this test:DdDDD
There is one actually. There isn't a specific video just for fermentati9on but I think he goes over fermentation briefly in the Oxidative phosphorylation and chemiosmosis video
I've learn more from you than through all of the text books i've read and all of the lectures i've attended. These videos and the website help me so much to continue enjoy the process of learning. Schools are so F-ed up because they make kids hate school, and hate learning. Learning should be a process enjoyed by everyone, and you are doing so much to help keep that alive!

you need to know how to teach and more into the lesson your more akward at teaching the concept your not too detail i will like to point out i understand this thousand times its just you cant explain it the right way you need to stay to that concept well explained
@biozamadotcom the processes are cyclical, radicals have their purpose(fighting infection, etc), just as "anti-oxidants" have their purpose. Issues arise when one or another is out of balance, or proportion. If something cannot be utilized it will just be removed from the body.

Oxidation.
Every heard of antiOxidants?
That's what they are for.
To keep your cells healthy and repaired.
