Exam 4: Physiology of Cells

Water will move through the cell membrane by:

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

For osmosis to occur,a selectively permeable membrane must be present.

A nurse was instructed to dissolve a pill in a small amount of liquid medication.As she dropped the capsule into the liquid,she was interrupted by a telephone call.On her return to the medication cart,she found the medication had completely dissolved and apparently scattered evenly throughout the liquid.This phenomenon did not surprise her because she was aware from her knowledge of cell transport that _____ had created this distribution.Explain this phenomenon.

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

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

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

Glycolysis does not require oxygen and is therefore termed anaerobic.

Because a living cell membrane can limit the diffusion of some substances by opening and closing channels,the membrane can be called selectively permeable.

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

Which factor can have an effect on the functioning of an enzyme?

Explain the classification system and naming system for enzymes.

Phagocytosis can be translated to "cell eating."

Endocytosis can occur when molecules bind to membrane receptor proteins.

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

All of the following are examples of passive transport except:

Allosteric effectors activate or inactivate enzymes by changing the shape of the enzyme's active site.

The hydrolyzing enzyme sucrase joins two sucrose molecules together.

Match each term with its description. -part of the cell in which glycolysis takes place

The enzyme that catalyzes the formation of sucrose is probably specific to that reaction.
