Bio CP Fall Semester Final Review

Front

What is the term for when both inside and outside of a cell have the same amount of water?

Back

Equilibrium

Front

In a hypotonic solution, where are most of the solutes located?

Back

Inside the cell

Front

In which osmotic state does the cell appear normal?

Back

Isotonic

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are the powerhouse of the cell, producing energy through cellular respiration.

Front

What is the movement of molecules against a concentration gradient called?

Back

Active transport

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes outside the cell than inside, causing the cell to lose water.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes outside the cell than inside, causing the cell to gain water.

Front

What is an isotonic solution?

Back

An isotonic solution has equal concentrations of solutes inside and outside the cell, resulting in no net movement of water.
