Which of the following steps within the citric acid cycle directly produces ATP (or GTP) as a side product?

Which of the following steps within the citric acid cycle does not produce as a side product?

Which of the following steps of the citric acid cycle results in the production of as a side product?

Which reaction of the citric acid cycle makes the entire process unidirectional (i.e. irreversible)?

Which of the following statements about the citric acid cycle is true?

Suppose that in a certain neuron, an action potential has caused $150:Na^{+}$ ions to enter the cell. In order to restore the resting membrane potential, the sodium-potassium pump uses 1 molecule of ATP to push $3:Na^{+}$ ions out of the cell and to bring $2: K^{+}$ ions into the cell. How many molecules of acetyl-CoA must pass through the citric acid cycle in order to provide enough energy for this process to occur?

Which of the following steps in the citric acid cycle do not have a largely negative $\small \Delta G$ ?
