EOC Review - Cell Membrane & Cell Transport

Front

What is the primary function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell, maintaining homeostasis.

Front

What is the structure of the cell membrane?

Back

The cell membrane is a phospholipid bilayer with embedded proteins.

Front

What does it mean for a membrane to be semipermeable?

Back

A semipermeable membrane allows certain substances to pass while blocking others.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What type of energy does passive transport use?

Back

Passive transport uses no energy.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane.

Front

What types of cells have a cell membrane?

Back

All cells, including prokaryotic and eukaryotic cells, have a cell membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is exocytosis?

Back

Exocytosis is a type of active transport that uses vesicles to expel large molecules from the cell.

Front

What is endocytosis?

Back

Endocytosis is a process where the cell engulfs substances to bring them into the cell.
