Cellular Transport Flashcard25f

Front

What is the primary function of the cell membrane?

Back

Controlling what enters and exits the cell

Front

What is the main structural component of the cell membrane?

Back

Phospholipids

Front

Why is the cell membrane described as a fluid mosaic?

Back

Its components, like lipids and proteins, move freely within the layer.

Front

What type of molecules can pass through the cell membrane without the help of transport proteins?

Back

Small, nonpolar molecules like oxygen and carbon dioxide

Front

Role of proteins in the cell membrane?

Back

They serve as channels, receptors, and enzymes

Front

The cell membrane is described as a bilayer because it consists of:

Back

Two layers of phospholipids

Front

What part of a phospholipid is hydrophobic?

Back

Lipid tail

Front

Which part of the phospholipid is hydrophilic?

Back

Phosphate head

Front

What is the function of cholesterol in the cell membrane?

Back

Helps maintain fluidity and stability
