24-25 Midterm Exam Review Part 6 (Cell transport, ATP/ADP)

Front

What is a hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes is lower outside the cell than inside, causing water to enter the cell, which may lead to swelling or bursting.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of solutes is higher outside the cell than inside, causing water to leave the cell, which may lead to shrinking.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution, such as salt in water.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution, such as water.

Front

What happens to a plant cell in a hypotonic solution?

Back

In a hypotonic solution, water enters the plant cell, causing it to swell and become turgid, which is essential for maintaining structure.

Front

What happens to a plant cell in a hypertonic solution?

Back

In a hypertonic solution, water leaves the plant cell, causing it to shrink and become plasmolyzed.

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 osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.
