Which of the following sequences correctly represents the flow of electrons during cellular respiration?

Which of the following terms most precisely identifies the cellular process of breaking down large molecules into smaller ones?

What is the name of the barrier that must be overcome before products are formed in a spontaneous reaction?

Fermentation is essentially glycolysis plus an extra step in which pyruvate is reduced to form lactate or alcohol and carbon dioxide. This last step __________.

Which of the following terms most precisely identifies the cellular process of breaking down large molecules into smaller ones?

Which of the following statements best describes how unsaturated fatty acids increase membrane fluidity at lower temperatures?

The phosphate transport system in bacteria imports phosphate into the cell even when the concentration of phosphate outside the cell is much lower than the cytoplasmic phosphate concentration. Because phosphate import depends on a pH gradient across the membrane, phosphate transport is most likely an example of which of the following transport processes? [Hint: pH indicates proton concentration, and suggest a proton pump]

In which reactions of cellular respiration does substrate-level phosphorylation occur?

A cell with a predominance of smooth endoplasmic reticulum is most likely specialized to carry out which of the following processes?
