Document Summary

Glucose (6c) oxidized into 2 molecules of pyruvate (3c each: 2 net atp, 2nadh, 2 pyruvate. Electrons removed are delivered to nad+ producing nadh. Atp produced during glycolysis is produced by kinase enzyme. 2 molecules of pyruvate still consume 75% of atp. Atp molecule produced in glycolysis result from substrate level phosphorylation. 1, which of the following processes occurs during glycolysis: atp production through substrate level phosphorylation. ^ active transport pyruvate + coa +nad+ acetyl-coa + nadh +h+ +co2 pyruvate must be transported across 2 membranes non selective porins allows diffusion across omm. Electrons removed in oxidations: accepted by nad+ or fad. Oxaloacetate: acetyl groups links to it and then it carries away the carbons in the cycle. 1 acetyl-coa +3 nad+ +1 fad +1adp+1 pi +2h2o 2co2+3nadh+1. Electrons passed from nadh and fadh2 to co2. 2 smaller mobile electron carriers- ubiquinone(uq)- non protein, & cytochrome c (cyt c)- protein- not a membrane protein but a soluble protein.

I know that this alot of questions, but it's kinda a last ditch effort. these are the last 42 definitions i have left to answer out of 500 question for my final exam study guide. so whatever help i can get is fine. No explanations needed just what each definition is explaining and thanks in advance ladies and gentlemen.
