Cell Membrane Review

Front

What are the hydrophobic tails of phospholipids?

Back

The hydrophobic tails of phospholipids are the nonpolar, water-repelling parts that are hidden in the middle of the cell membrane.

Front

What are the characteristics of the tails of a phospholipid?

Back

The tails of a phospholipid are hydrophobic and nonpolar.

Front

What does hydrophilic mean?

Back

Hydrophilic means 'water loving', referring to substances that are attracted to water.

Front

What are transport proteins?

Back

Transport proteins are proteins found in the cell membrane that function as channels or pumps to move substances across the membrane.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to regulate what enters and leaves the cell.

Front

What is a phospholipid?

Back

A phospholipid is a type of lipid molecule that is a major component of cell membranes, consisting of a hydrophilic head and two hydrophobic tails.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.

Front

What role do receptor proteins play in the cell membrane?

Back

Receptor proteins are involved in signaling and communication between the cell and its environment.

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 is the difference between hydrophobic and hydrophilic substances?

Back

Hydrophobic substances repel water, while hydrophilic substances are attracted to water.
