Front

What allows cells to recognize each other and act like ID tags?

Back

Carbohydrates

Front

What strengthens and stabilizes the cell membrane?

Back

Cholesterol

Front

How does rinsing with warm salt water help swollen gums?

Back

Water in the gums will diffuse out of the cells.

Front

What type of cellular transport is represented by the process of vesicles fusing with the plasma membrane to release contents outside the cell?

Back

Exocytosis

Front

What is composed of a phosphate and glycerol head and 2 fatty acid chain tails?

Back

Phospholipid

Front

What is the primary function of the cell membrane?

Back

To regulate the movement of substances in and out of the cell.

Front

What is the fluid mosaic model?

Back

A model that describes the structure of cell membranes as a mosaic of various components, including phospholipids, cholesterol, and proteins.

Front

What role do proteins play in the cell membrane?

Back

Proteins function as channels, carriers, and receptors to facilitate communication and transport.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.
