Front

What is the name of the structure labeled G?

Back

glycolipid

Front

In relatively warm temperatures, cholesterol makes the membrane _____________ by ____________ the movement of phospholipids.

Back

less fluid, restraining

Front

What is the primary function of phospholipids in the cell membrane?

Back

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

Front

What role do carbohydrates play in the cell membrane?

Back

They serve as recognition sites for cell signaling and communication.

Front

What is the structure of a phospholipid?

Back

A hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Front

How does cholesterol affect membrane fluidity at high temperatures?

Back

It makes the membrane less fluid by restraining the movement of phospholipids.

Front

What is a glycolipid?

Back

A lipid with a carbohydrate attached, important for cell recognition.
