Cell Membrane & Cell Transport

Front

What does 'Hydrophilic' mean?

Back

Hydrophilic refers to substances that are 'water-loving' and can easily interact with water.

Front

What does 'Selectively Permeable' mean?

Back

Selectively permeable means that a membrane allows some molecules to pass through while blocking others.

Front

What is Osmosis?

Back

Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Which components are part of the cell membrane?

Back

The cell membrane is primarily composed of lipids, carbohydrates, and proteins.

Front

What is the function of the Cell Membrane?

Back

The cell membrane controls the passage of materials in and out of the cell, maintaining homeostasis.

Front

What are Lipids?

Back

Lipids are organic compounds that are insoluble in water and are a major component of cell membranes.

Front

What are Proteins in the context of cell membranes?

Back

Proteins in cell membranes serve various functions, including transport, signaling, and structural support.

Front

What role do Carbohydrates play in the cell membrane?

Back

Carbohydrates on the cell membrane are involved in cell recognition and communication.

Front

What is the difference between Hydrophobic and Hydrophilic substances?

Back

Hydrophobic substances repel water, while hydrophilic substances attract and interact with water.

Front

What is a Semi-Permeable Membrane?

Back

A semi-permeable membrane allows certain molecules to pass through while restricting others.
