Mid-Term Review Part 1

Front

What does a catalyst do?

Back

Speeds up a chemical reaction.

Front

Movement of particles from high to low concentration is called?

Back

Passive Transport.

Front

Which of these is not a form of passive transport?

Back

Endocytosis.

Front

The cell is in a _____________ solution if it has a lower concentration of solutes than the surrounding solution.

Back

Hypotonic.

Front

What is the definition of OSMOSIS?

Back

Diffusion of water through a selectively permeable membrane.

Front

What is the role of a selectively permeable membrane?

Back

Controls what enters and leaves the cell.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move molecules against the concentration gradient.

Front

What is diffusion?

Back

Movement of molecules from an area of high concentration to an area of low concentration.

Front

What happens to a cell in a hypertonic solution?

Back

It shrinks due to water loss.

Front

What is facilitated diffusion?

Back

A process that uses transport proteins to move molecules across the cell membrane without energy.
