What is the type of transport protein that carries large molecules such as glucose through the cell membrane?

Back

Carrier protein

Front

What is the term for the diffusion of water molecules through a membrane?

Back

Osmosis

Front

What is the process called when a cell takes in a substance by surrounding it with the cell membrane?

Back

Endocytosis

Front

What do we call the amount of something per unit of volume?

Back

Concentration

Front

What is the movement of substances through a cell membrane by using the cell's energy called?

Back

Active transport

Front

What is the primary function of carrier proteins in the cell membrane?

Back

To facilitate the transport of large molecules across the membrane.

Front

How does osmosis differ from simple diffusion?

Back

Osmosis specifically refers to the movement of water molecules, while simple diffusion refers to the movement of solutes.

Front

What are the two main types of transport across cell membranes?

Back

Passive transport and active transport.

Front

What is the role of concentration gradients in the movement of substances across membranes?

Back

Substances move from areas of higher concentration to areas of lower concentration during passive transport.

Front

What is the significance of active transport in cellular function?

Back

Active transport allows cells to move substances against their concentration gradient, which is essential for maintaining homeostasis.
