Exam 6: Cell Function

Diffusion of water through a selectively permeable membrane in the presence of at least one impermeable solute is referred to as:

Diffusion of particles through a membrane by means of a carrier molecule is called:

Most of the chemical energy released by the citric acid cycle is in the form of ATP.

Protein synthesis is an anabolic pathway for cells.

The vesicles used in exocytosis have broken off from the mitochondria and are pulled to the cell membrane by the cytoskeleton.

Which of the following is not true of the citric acid cycle?

Which is true about the sodium and potassium pump?

Match the name of each enzyme with its function or description. -Digestive enzymes

A membrane carrier structure attracts a solute to a binding site, changes shape, and releases the solute on the other side of the cell membrane. This describes the process of:

Anne ran in the Boston marathon. During the race, she lost a large amount of hypotonic sweat. Would you expect her cells to shrink, swell, or remain the same? Explain your answer.

The process of end-product inhibition in a metabolic pathway is an example of a positive-feedback loop.

Endocytosis can occur when molecules bind to membrane receptor proteins.

All of the following are examples of passive transport except:

Cellular secretion can be achieved by endocytosis.

A semipermeable membrane is needed for diffusion to occur.

Name the three types of vesicle-mediated transport and explain how they are different.
