Cell Transport

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing the cell to swell as water enters.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane against their concentration gradient, requiring energy.

Front

What is a phospholipid bilayer?

Back

The phospholipid bilayer is a double layer of phospholipids that makes up the cell membrane, providing structure and protection.

Front

What role do peripheral proteins play in the cell membrane?

Back

Peripheral proteins are attached to the surface of the membrane and help with cell recognition and signaling.

Front

What is the function of integral proteins?

Back

Integral proteins span the membrane and assist in transporting substances across the cell membrane.

Front

What is the role of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's fluidity and structure.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells engulf substances from the outside environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials to the outside environment.
