cell transport test

Which of the following is NOT an example of passive transport.

Passive transport moves particles from [blank_start]high[blank_end] concentrations to [blank_start]low[blank_end] concentrations.

The function of ATP is to produce energy.

What substances ONLY enter the cell?

The Definition of Homeostasis is[blank_start]_____[blank_end]?

1. Equilibrium- When all the concentrations in a substance are uniform.

2. Diffusion- The diffusion of water across a selectively permeable membrane

Diffusion Is_____.

Osmosis is___.

Facilitate Diffusion- Uses transport proteins to move ions and small molecules across the plasma membrane

The process of large particles entering the cell is____.

The process of large particles leaving the the cell is____.

Active transport happens when particles go from a low concentration to a high concentration.

Passive transport uses cellular energy.

Active transport uses cellular energy.

What is the main function of the plasma membrane?

Which of the following are compounds of the plasma membrane?

1.) Transmit signals to the inside of the cell, serve as support structures for the membrane, and move needed substances and wastes through the membrane.------ [blank_start]Proteins[blank_end] 2.)
