3. True or False [ ] In glycolysis, a single glucose molecule breaks down into two molecules of pyruvate, which can then be broken down further to release ATP. Glycolysis itself releases four net molecules of ATP per molecule of glucose. [ ] The main products in glycolysis include ATP, pyruvate and NADPH. [ ] In the preparatory phase of glycolysis, ATP is invested to convert glucose to fructose 1,6-bisphosphate. The bond between C-2 and C-3 is then broken to...

a. The metabolism of glucose by glycolysis to acetyl-coenzyme A, followed by the TCA cycle, releases CO2 molecules by oxidative decarboxylation reactions. Write down the oxidative decarboxylation reactions that result in CO2 production. Name the enzyme involved in each reaction and give the names and complete structures of all reactants and products. Only abbreviated names of enzyme cofactors are required. (b) From the steps drawn in part (a) above, how many total ATP molecules would be produced from oxidative phosphorylation?

A. Make a table comparing the three main events of aerobic cellular respiration: glycolysis, Kreb's Cycle, and electron transport chain. For each stage list the input molecule, the products (including any energized electron carriers, NADH and/or FADH), the number of ATP generated in each stage for every one glucose molecule that begins the process, and the location in the cell.

Be able to label any and all steps in: glycolysis, the citric acid cycle and oxidative phosphorylation. Including (but not limited to): names of compounds, enzymes (for extra credit where stated), ATP produced, NADH and FADH2 produced, and the role or importance of main molecules. **Note: this is really three questions in one. Therefore, know how to label the sequences in 1. Glycolysis 2. The citric acid cycle and 3. Oxidative phosphorylation .
