324 Cell Membrane and Transport Assessment 2024 Nelson

Front

What is passive transport?

Back

Cell membrane transport that occurs without energy.

Front

What happens to a slug when salt is poured on it?

Back

Water will move out of the slug's cells and the cells will shrink.

Front

What is the phospholipid bilayer?

Back

A double layer of phospholipids that makes up the cell membrane.

Front

What is a carrier or transport protein?

Back

A protein that helps transport substances across a cell membrane.

Front

What are lipid tails?

Back

Hydrophobic components of phospholipids that repel water.

Front

What is active transport?

Back

Cell membrane transport that requires energy to move substances against their concentration gradient.

Front

What is endocytosis?

Back

The process by which cells take in substances by engulfing them.

Front

What is exocytosis?

Back

The process by which cells expel substances by vesicles fusing with the membrane.

Front

What role do carbohydrates play in the cell membrane?

Back

They are involved in cell recognition and signaling.

Front

What is the function of cholesterol in the cell membrane?

Back

It helps to stabilize the membrane's fluidity.
