Cell Membrane Flashcard

Front

What type of lipid is found in the cell membrane?

Back

Phospholipid

Front

What is the role of cholesterol in the cell membrane?

Back

Maintains fluidity and stability

Front

What is structure B in the context of cell membrane components?

Back

Carbohydrate chain

Front

What is the hydrophilic (non-polar) part of a phospholipid?

Back

Phospholipid head

Front

What are the two main components of a phospholipid?

Back

Hydrophilic head and hydrophobic tail

Front

What is the function of channel proteins in the cell membrane?

Back

Facilitate the transport of substances across the membrane.

Front

What is the difference between hydrophilic and hydrophobic molecules?

Back

Hydrophilic molecules are attracted to water, while hydrophobic molecules repel water.

Front

What is a glycoprotein and its role in the cell membrane?

Back

A glycoprotein is a protein with carbohydrate chains that aids in cell recognition and communication.

Front

What is the fluid mosaic model of the cell membrane?

Back

It describes the cell membrane as a flexible layer made of lipid molecules with embedded proteins.

Front

How do phospholipids arrange themselves in a cell membrane?

Back

They form a bilayer with hydrophilic heads facing outward and hydrophobic tails facing inward.
