Daily Review Flashcard - Cell Membrane Structure (Task 11)

Front

What is the primary component that makes up the cell membrane?

Back

Phospholipids.

Front

What does the suffix -philic mean?

Back

Loving.

Front

What term describes a membrane that allows some molecules to cross while others cannot?

Back

Selectively (or Semi) Permeable.

Front

In a phospholipid molecule, which end is hydrophilic?

Back

The head.

Front

In a phospholipid molecule, which end is hydrophobic?

Back

The tail.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic 'head' and two hydrophobic 'tails'.

Front

What role do phospholipids play in the cell membrane?

Back

They form a bilayer that acts as a barrier to most water-soluble substances.

Front

What is the significance of the fluid mosaic model in cell membrane structure?

Back

It describes the cell membrane as a dynamic and flexible structure with various proteins embedded in or attached to a fluid lipid bilayer.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the membrane's fluidity and integrity.

Front

What are integral proteins?

Back

Proteins that are embedded within the lipid bilayer and can span across the membrane.
