Unit 2 review- Energy and Cell Transport

Front

What happens to a cell in an isotonic solution?

Back

The cell stays the same size.

Front

What type of solution is a cell in if it shrinks?

Back

Hypertonic solution.

Front

What type of solution is a cell in if it swells?

Back

Hypotonic solution.

Front

What is the correct equation for cellular respiration?

Back

6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy.

Front

What is active transport?

Back

The movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is passive transport?

Back

The movement of molecules across a cell membrane without the use of energy, typically from a region of higher concentration to a region of lower concentration.

Front

Define diffusion.

Back

The process by which molecules spread from an area of high concentration to an area of low concentration.

Front

Define osmosis.

Back

The diffusion of water molecules through a selectively permeable membrane.

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing cells to swell.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing cells to shrink.
