    Don't let your teacher affect your love of science. You can be a scientist outside of the classroom too. Be your own teacher. Keep your love of learning and you will do just fine.

    Whoa, you honestly made everything clear without me having to look over my notes and textbook all the time and to memorize the whole steps of glycolysis which confuses me sometimes. You are very neat. You showed helpful visuals, flow charts, good facts, and clear explanations. Seriously, THANK YOU SO MUCH sir. I'll be having a test sooner this week and I feel pretty confident now!

    Thank you VERY MUCH Craig for these videos. I see you put in quite an effort and time to make these videos to it completion there. Your tutoring is very clear, to the point, and learning re-enforcing. I understand the whole process or should I say processes now. This is much better than sitting through lectures for hours. Thank you again!

    While this seems like a detailed look at glycolysis, I have actually left out many intermediate steps in this very complex biochemical pathway. So some things seems to appear from nowhere like these two extra phosphate groups. The conversion of PGAL into BPGA actually occurs in two steps with the enzyme "triose phosphate dehydrogenase" First it transfers the Hydrogen to NAD+ then it add the Phosphate groups to the oxidize PGAL- These phosphates are FROM THE CYTOSOL (available raw materials)

    38 ATP is the number of ATP formed during the process of cellular respiration. 2 are formed during glycolysis and the other 36 are formed in the kreb's/citric acid cycle.

  • @TravelWithPreston
    @TravelWithPreston 9 років тому +1

    Confused. During the first step, 2 ATP molecules are used to split the Glucose molecule in half, thus leaving 2 ADP molecules. During the BPGA step, those 2 ADP molecules become 2 ATP molecules via substrate level phosphorlyation; in which BPGA becomes PGA.
    HOWEVER, if those 2 ADP molecules have already been used.. how does another 2 ADP's get used just before the pyruvate step?

  • @rendavis4945
    @rendavis4945 11 років тому

    Hey there, I think the term you're looking for is cytosol. The cytosol is the liquid part comprised mostly of water in which all the organelles of the cell reside, while cytoplasm is a collective term for the cytosol PLUS the organelles in it. Technically, since it's not taking place in any organelle (like Mitochondria), Glycolysis DOES take place in the cytosol. Hope this helped!
