Cell Homeostasis

Front

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

Back

active transport

Front

Which homeostatic process moves particles against a concentration gradient?

Back

active transport

Front

What describes the ability of the cell membrane to allow various substances to move through it?

Back

The cell membrane is selectively permeable.

Front

Which best describes dynamic equilibrium?

Back

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

Front

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

Back

isotonic

Front

Process characterized by movement of particles from high to low concentration across plasma membrane without energy use.

Back

passive transport

Front

For diffusion to occur, which condition must be met?

Back

A concentration gradient must exist.

Front

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? Options: osmosis, passive transport, active transport, diffusion

Back

active transport

Front

Which motion of particles across a membrane requires energy? Options: from high concentration to low concentration, from low concentration to high concentration, with no concentration gradient, through dynamic equilibrium

Back

from low concentration to high concentration

Front

Which best describes the difference between osmosis and diffusion? Options: Osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration., 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., Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration., Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.
