If Citrate Levels Are High in the Cell, but ATP

question 11

Multiple Choice

If citrate levels are high in the cell, but ATP levels are low, what do you think will happen in the cell?

• A)In the presence of glucose, glycolysis will run to generate energy for the cell, but the Krebs cycle will be inhibited.
• B)Glycolysis will be inhibited, but the Krebs cycle will be functional, allowing it to be utilized to breakdown acetyl-CoA generated from beta-oxidation.
• C)The electron transport chain will be inhibited, causing a build-up of NADH and FADH₂.This will inhibit the Krebs cycle, but in the presence of glucose, glycolysis will still run coupled with fermentation to regenerate NAD⁺.
• D)Glycolysis and the Krebs cycle will both be inhibited, thus under these conditions there will be no mechanism to generate ATP.
