What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy in the form of ATP.

Front

What energy molecule is required for active transport?

Back

ATP (Adenosine Triphosphate) is the energy molecule required for active transport.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside, causing water to move out of the cell.

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 hypotonic solution?

Back

A hypotonic solution is one where the concentration of solutes is lower outside the cell than inside, causing water to move into the cell.

Front

What does the acronym I-PMAT stand for in mitosis?

Back

I-PMAT stands for Interphase, Prophase, Metaphase, Anaphase, and Telophase, which are the stages of mitosis.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell takes in particles by engulfing them in a vesicle.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell releases substances in a vesicle to the outside environment.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically moving from high to low concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient.
