Review 3: Pyruvate & Fatty Acid Oxidation, Citric Acid Cycle, & Glycogen Metabolism

In aerobic respiration, one glucose molecule is converted to two molecules of acetyl-CoA that enter the citric acid (Krebs) cycle. How many turns of the citric acid cycle occur per glucose molecule?

In eukaryotic cells, where does the Krebs (citric acid) cycle primarily take place?

In the citric acid (Krebs) cycle, why is the pathway considered a “cycle”?

In the citric acid (Krebs) cycle, how much ATP (or equivalent GTP) is produced directly by substrate-level phosphorylation per turn of the cycle for one acetyl-CoA?

In eukaryotic cells, the Krebs (citric acid) cycle primarily takes place in which location?

In eukaryotic cells, where do the reactions of the tricarboxylic acid (TCA) cycle primarily take place?

In cellular respiration, what is the primary function of the Krebs (citric acid) cycle?

In eukaryotic cells, where does the Krebs (citric acid) cycle primarily occur?

In the citric acid (Krebs) cycle, how many molecules of ATP (or GTP, ATP-equivalent) are produced directly by substrate-level phosphorylation per turn of the cycle (per acetyl-CoA)?

In the citric acid (Krebs) cycle, how many ATP molecules are produced directly (as substrate-level phosphorylation) per turn of the cycle for each acetyl-CoA that enters?

In human aerobic metabolism, which molecule is the primary waste product ultimately produced from complete oxidation of carbon fuels in the citric acid cycle and oxidative phosphorylation?

In one turn of the citric acid (Krebs) cycle per acetyl-CoA (excluding ATP from oxidative phosphorylation), what is the direct energy yield in terms of reduced cofactors and substrate-level phosphorylation?

In eukaryotic cells, where does the Krebs (citric acid) cycle primarily occur?

In one turn of the citric acid (Krebs) cycle per acetyl-CoA, how many molecules of $F_{AD{H}_2}$ are produced?

In the citric acid (Krebs) cycle, why is it described as a "cycle"?
