Exam 6: Cell Function

In aerobic respiration, the function of oxygen is to combine with:

Explain how the allosteric site on an enzyme allows the enzyme to function. Explain the types of allosteric effectors.

The _____ pressure of a solution is the pressure that prevents the movement of water by osmosis from pure water into the solution.

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

The physical movement of water and solutes through a membrane when a hydrostatic pressure gradient exists is called filtration.

Briefly explain the process of glycolysis. What energy molecules are produced, and how many of each are produced?

A hypertonic solution has a higher amount of osmotic potential than any other type of solution.

The size of the molecule is an important factor in both dialysis and filtration.

Match the name of each enzyme with its function or description. -Add water to a molecule without splitting it

Dialysis is a form of filtration that results in a separation of small and large solute particles.

Which enzymes rearrange atoms within a molecule?

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.

Endocytosis and pinocytosis are both active transport processes, because they require a carrier system such as a pump.

The citric acid cycle and electron transport system are located in the Golgi apparatus.

Match the name of each enzyme with its function or description. -Rearrange atoms within a molecule

The process of glycolysis produces two molecules of pyruvate for every one molecule of glucose.

Phagocytosis is an example of:

The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of:

The three processes that comprise cellular respiration are glycolysis, the citric acid cycle, and the proton transport system.

The sodium-potassium pump is an example of a passive transport process.
