Pyruvic acid in the cytosol outside the mitochondrian b. Passes into the mitochondrian i. A lot of processes take place (3) 1. mechanism for removing a carboxyl group and co2 2. Oxydizing the acetate group converting an NAD+ TO NADH 3. reacts with a sulfur containing coenzyme with a high- energy bond and produce Acetyl coenzyme A (Acetyl CoA) ii. Goes on to the Kreb Cycle III. Kreb Cycle (discovered by Hans Kreb) a. Acetyl CoA comes into the doorway i. Enzymatically in the first step a bond Is broken and just the acetate fragment is left ii. This is combined with Oxaloacetic acid to create a six carbon molecule (citric acid) b. Citric acid i. Does something to becom an isocitric acid c. Converts another NAD+ to NADH and reduces i. Now have a five carbon molecule called alph-Ketoglutaric acid d.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
