Back

Enzymes are catalysts that speed up chemical reactions in the body.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy (ATP) to move substances against their concentration gradient.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
