Cell Homeostasis — Quiz

Question 1

In which kind of solution is the concentration of solutes the same inside and outside of the cell?

Revolt · Accepted Answer

isotonic

Question 2

For diffusion to occur, which condition must be met?

Revolt · Accepted Answer

A concentration gradient must exist.

Question 3

Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?

Revolt · Accepted Answer

passive transport

Question 4

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins?

Revolt · Accepted Answer

active transport

Question 5

Which motion of particles across a membrane requires energy?

Revolt · Accepted Answer

from low concentration to high concentration

Question 6

Which best describes the difference between osmosis and diffusion?

Revolt · Accepted Answer

Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.

Question 7

Which best describes dynamic equilibrium?

Revolt · Accepted Answer

Particles are moving into and out of the cell, but their concentrations remain stable.

Question 8

Which homeostatic process moves particles against a concentration gradient?

Revolt · Accepted Answer

active transport

Question 9

Which homeostatic process requires energy to move particles across the plasma membrane?

Revolt · Accepted Answer

active transport

Question 10

Which statement describes the ability of the cell membrane to allow various substance to move through it?

Revolt · Accepted Answer
