Cell Membrane 2.0

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 primarily composed of a phospholipid bilayer.

Front

What does 'semipermeable' mean in the context of the cell membrane?

Back

Semipermeable means that the cell membrane allows certain substances to pass while blocking others.

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the cell membrane, consisting of hydrophilic heads and hydrophobic tails.

Front

What does hydrophobic mean?

Back

Hydrophobic refers to substances that repel water; in the cell membrane, it describes the tails of phospholipids.

Front

What does hydrophilic mean?

Back

Hydrophilic refers to substances that attract water; in the cell membrane, it describes the heads of phospholipids.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, communication, and structural support.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's fluidity.

Front

What are carbohydrate chains in the cell membrane?

Back

Carbohydrate chains are attached to proteins and lipids, playing a role in cell recognition and signaling.

Front

What types of molecules can easily pass through the cell membrane?

Back

Small, nonpolar molecules can easily pass through the cell membrane.
