Cell Transport Review

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell, which may lead to swelling or bursting.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to leave the cell, which may lead to shrinkage.

Front

What is an isotonic solution?

Back

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

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 active transport?

Back

Active transport is the process of moving molecules across a cell membrane against their concentration gradient, requiring energy (ATP).

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf substances from the outside environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel large molecules or waste products by enclosing them in vesicles that fuse with the cell membrane.

Front

What role does the cell membrane play in transport?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution; in biological systems, water is often the solvent.
