Which type of macromolecule stores energy most efficiently?

A. lipids

B. carbohydrates

Which of the following terms describes the movement of oxygen from red blood cells into other cells in the body?

A. Osmosis.

B. Endocytosis.

C. Diffusion.

D. Facilitated diffusion.

Explanation:

Diffusion is the tendency of molecules to move from an area of high concentration to one of low concentration. Thus, oxygen diffuses out of red blood cells, into the fluid surrounding our other cells, and then into the cells themselves, where the concentration of oxygen is lower.

A. The opening of gap junctions.

B. The binding of the message molecule to the receptor.

C. A portion of the cell membrane folding inward and pinching off.

D. Diffusion of material through the cell wall.

Explanation:

When a message molecule reaches the specific receptor protein it can bind to, it sets off a series of chemical reactions that ultimately lead to the cell responding to the message.

Enzymes

A. allow reactions to happen more quickly.

B. raise the activation energy of reactions.

C. must be replenished by cells as they are used up in reactions.

D. Both A and B.

Explanation:

Enzymes, which lower the activation energy of a reaction, are not altered or destroyed in the reaction they catalyze and so do not have to be replaced by the cell.

Which type of inhibition is illustrated by the action of cyanide on the human body?

A. Competitive.

B. Noncompetitive.

C. Controlled.

D. Uncontrolled.

Explanation:

Competitive inhibition is the process by which an inhibitor such as cyanide binds to the active site of an enzyme, preventing it from binding its substrate.

What happens in the chlorophyll molecule of a plant?

A. Chlorophyll harvests energy from the electron transport chain.

C. Molecules of G3P are combined to make one molecule of glucose.

D. Chlorophyll captures electrons from sunlight and uses them to turn oxygen into water.

Explanation:

Chlorophyll is crucial to the light-dependent reactions of photosynthesis. Sunlight strikes the chlorophyll molecule, knocking out an electron, which forces chlorophyll to grab an electron from water.
