Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, providing protection and support.

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the cell membrane, consisting of a hydrophilic (water-loving) head and two hydrophobic (water-hating) tails.

Front

What role does cholesterol play in the cell membrane?

Back

Cholesterol helps to regulate the fluidity of the cell membrane, keeping it stable at varying temperatures.

Front

What are glycoproteins?

Back

Glycoproteins are proteins with carbohydrate chains attached, important for cell communication and recognition.

Front

What are glycolipids?

Back

Glycolipids are lipids with carbohydrate chains attached, also playing a role in cell recognition and communication.

Front

What does selective permeability mean?

Back

Selective permeability refers to the ability of the cell membrane to allow certain substances to pass while blocking others.

Front

What happens to phospholipids when the temperature increases?

Back

When the temperature increases, phospholipids can separate too much, which may disrupt the selective permeability of the membrane.

Front

What is the hydrophilic part of a phospholipid?

Back

The hydrophilic part of a phospholipid is the head, which is attracted to water.

Front

What is the hydrophobic part of a phospholipid?

Back

The hydrophobic part of a phospholipid is the tail, which repels water.

Front

Why are cell membranes described as fluid mosaics?

Back

Cell membranes are described as fluid mosaics because they are flexible and composed of various proteins and lipids that move freely within the layer.
