Front

Which of the following is NOT a type of passive transport? Options: Osmosis, Diffusion, Endocytosis

Back

Endocytosis

Front

Active transport allows a cell to move molecules from an area of low concentration to an area of high concentration.

Back

True

Front

What allows some things to enter and leave cells, while keeping other things out of the cell?

Back

A selectively permeable membrane

Front

Cells sometimes use energy to transport materials across the cell membrane. This is called

active transport

When the concentration of solutes on both sides of a membrane is the SAME, the solution is

Back

isotonic

Front

A process for removing large quantities of toxins and waste from the cell is: exorcism, exocytosis, endocytosis, endoplasmic reticulum

Back

exocytosis

Front

Facilitated diffusion involves movement of molecules across a membrane when they bond to: channel proteins, lipid proteins, a protein pump (carrier protein), sticky proteins

Back

channel proteins
