Biomolecules + Homeostasis, Osmosis + Diffusion

Front

What is the definition of biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What are the main types of biomolecules?

Back

The main types of biomolecules are carbohydrates, proteins, lipids, and nucleic acids.

What role do carbohydrates play in the body?

Back

Carbohydrates provide quick energy for the cell and are a primary source of energy for the body.

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment in an organism.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, including diffusion and osmosis.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

How do diffusion and osmosis differ?

Back

Diffusion refers to the movement of solute molecules, while osmosis specifically refers to the movement of water molecules.

Front

What is the significance of a concentration gradient in diffusion?

Back

A concentration gradient is the difference in concentration of a substance between two areas, and it drives the process of diffusion.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.
