A high ADP:ATP ratio in cells influences glucose breakdown in cells. How does it do this? it exercises allosteric regulation of ATP synthase. it activates enzymes in the glycolytic pathway. it inactivates enzymes in the citric acid cycle. it promotes fermentation. it accelerates transfer of electrons in the electron transport chain.

Citric acid (or citrate) is an allosteric inhibitor of one of the first enzymes in glycolysis. How, in general, will it affect cellular respiration? Glycolysis will slow down when citric acid is abundant It will compete with glucose for the active site of the enzyme. It will stop the citric acid cycle when pyruvate is abundant. All of the above
Which of the following energy producing pathways in our bodies does NOT require energy? (Choose all that are correct) glycolysis cellular respiration creatine phosphate
Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 38 ATP from one glucose molecule. What happens to the rest of the energy in glucose? It is stored as fat. It is converted to heat. It is used to make water from hydrogen ions and oxygen. It is released as carbon dioxide and water It is converted to starch.
What happens to the ATP made during glycolysis and the citric acid cycle? It is used to drive cellular reactions. It is used to drop off electrons into the electron transport chain. It is used to drive the formation of acetyl-CoA. It is not used by the cell.
ATP is NOT directly produced by which of the following reactions? glycolysis the preparatory reaction the TCA cycle the electron transport chain and oxidative phosphorylation all of these produce ATP directly
Which set of reactions are most efficient at making ATP from the breakdown of glucose? electron transport chain glycolysis acetyl-CoA formation citric acid cycle
The complete oxidation of one molecule of glucose results in the production of 38 molecules of ATP. Specifically, where do these molecules of ATP come from? All 38 molecules of ATP are synthesized during oxidative phosphorylation and electron transport. All 38 molecules of ATP are synthesized during glycolysis. 2 net ATP molecules from glycolysis; 2 NADH molecules from glycolysis are oxidized resulting to 6 ATP molecules; 2 NADH molecules from pyruvate processing are oxidized resulting to 6 ATP molecules; 2 net ATP from Krebs Cycle; 6 NADH molecules from Krebs Cycle are oxidized resulting to 18 ATP molecules 2 FADH2 molecules from Krebs Cycle are oxidized resulting to 4 ATP molecules 2 net ATP molecules from glycolysis; 2 NADH molecules from glycolysis are oxidized resulting to 2 ATP molecules; 2 NADH molecules from pyruvate processing are oxidized resulting to 2 ATP molecules; 2 net ATP from Krebs Cycle; 6 NADH molecules from Krebs…
