Exam 6: Cell Function

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

Facilitated diffusion and simple diffusion move substances in opposite directions.

Which enzymes rearrange atoms within a molecule?

Coenzymes join enzymes to form proenzymes.

The "lock-and-key model" is used to describe how mRNA and tRNA base pairs align.

Match each term with its description. -Carries the end product of glycolysis to the citric acid cycle

Match the name of each enzyme with its function or description. -Involved in oxidation-reduction reactions

A side effect of exocytosis is the addition of new membrane material to the cell membrane.

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

Match the name of each enzyme with its function or description. -Add or remove phosphate groups

Most enzymes cannot catalyze a reaction in both directions.

Which of the following is not a passive transport process?

Match each term with its description. -Part of the cell in which citric acid cycles take place

To maintain homeostasis, the sodium-potassium pump moves equal amounts of sodium and potassium into and out of the cell.

The location at which the enzyme molecule binds to the substance it acts on is called the:

Because of the phospholipid cell membrane, water cannot diffuse into or out of the cell.

The electron transport system makes ATP by the movement of electrons through the inner mitochondrial membrane.

Glycolysis does not require oxygen and is therefore termed anaerobic.

All enzyme names end with the suffix "-ase."

Diffusion requires:
