Anatomy Part 2 Retake

Front

What is diffusion?

Back

Movement of molecules from high concentration to low concentration.

Front

What is osmosis?

Back

The diffusion of water molecules across a membrane.

Front

What type of energy powers Active Transport?

Back

ATP.

Front

What type of transport requires energy to move molecules against a concentration gradient?

Back

Active transport.

Front

True or False: Osmosis is an active process and requires extra energy for it to occur.

Back

False.

Front

Define passive transport.

Back

The movement of molecules across a cell membrane without the use of energy.

Front

What is facilitated diffusion?

Back

A process that allows molecules to cross membranes with the assistance of special proteins.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

Explain the role of ATP in cellular processes.

Back

ATP provides the energy required for many cellular processes, including active transport.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.
