Cell Membrane

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and leaves the cell, providing protection and support.

Front

What is the structure of the cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer with embedded proteins.

Front

What does 'selectively permeable' mean?

Back

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

Front

What role do proteins play in the cell membrane?

Back

Proteins form channels and pumps that help transport substances across the membrane.

Front

What is a phospholipid?

Back

A phospholipid is a molecule that makes up the cell membrane, consisting of a hydrophilic head and two hydrophobic tails.

Front

What does 'homeostasis' refer to in the context of cells?

Back

Homeostasis refers to the maintenance of a stable internal environment within the cell.

Front

What is the significance of the fluid mosaic model?

Back

The fluid mosaic model describes the cell membrane as a flexible structure with various proteins floating in or on the fluid lipid bilayer.

Front

What are carbohydrates' role in the cell membrane?

Back

Carbohydrates are involved in cell recognition and signaling.

Front

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

Back

Bilayer refers to the two layers of phospholipids that make up the cell membrane.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
