Cell Transport- viramontes

Front

What is a Hypertonic Solution?

Back

A solution with a higher concentration of solute (like salt or sugar) outside a cell than inside, causing water to move out of the cell, leading to cell shrinkage.

Front

What is a Solvent?

Back

The liquid in which substances are dissolved; in biology, this is usually water.

Front

What is ATP?

Back

Adenosine triphosphate, the molecule used directly by cells for energy in cellular processes.

Front

What is Exocytosis?

Back

The active transport process of moving molecules (often waste products) out of a cell using ATP.

Front

What does Synthesis mean in biology?

Back

The process of assembling or putting together large molecules (polymers) from smaller parts (monomers).

Front

What is a Hypotonic Solution?

Back

A solution with a lower concentration of solute outside a cell than inside, causing water to move into the cell, potentially leading to cell swelling.

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

The movement of molecules against a concentration gradient, requiring energy (ATP) to move substances into or out of a cell.

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses transport proteins to help move molecules across the cell membrane.

Front

What is a Solute?

Back

A substance that is dissolved in a solvent, forming a solution.
