In liver cells, the inner mitochondrial membranes contain about five times the surface area of the outer mitochondrial membranes, which allows for increased rates of which process below?

The citric acid cycle. Which of the following combinations of products would result from three acetyl CoA molecules entering the citric acid cycle?

Which of the following statements best describes the electron transport chain?

The standard free energy for the complete oxidation of glucose to CO₂ and water is -686 kcal/mol, and the standard free energy for the reduction of NAD+ to NADH is +53 kcal/mol. Which of the following statements best explains why only two molecules of NADH are formed in glycolysis when up to 12 molecules could theoretically be produced?

Which of the following statements best supports the claim that glycolysis is likely one of the first metabolic pathways to have evolved?

Which of the following molecules is the lowest-energy donor of electrons to the electron transport chain?

High levels of citric acid inhibit the enzyme phosphofructokinase, a key enzyme in glycolysis. Citric acid binds to the enzyme at a different location than the active site. This is an example of which of the following?

A typical eukaryotic cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen to an individual when they exhaust their ATP supply?
