Macromolecules & Carbon Cycle Review

Front

What is a macromolecule?

Back

A macromolecule is a large, complex molecule, such as proteins, nucleic acids, carbohydrates, and lipids, that are essential for life.

Front

What are the four main types of macromolecules?

Back

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

Front

What is the primary function of carbohydrates?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What is the role of lipids in living organisms?

Back

Lipids store energy, provide insulation, and make up cell membranes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the carbon cycle?

Back

The carbon cycle is the process through which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What is a characteristic of proteins?

Back

Proteins are made up of amino acids and play a crucial role in building and repairing tissues.

Front

What is the significance of carbon dioxide in the carbon cycle?

Back

Carbon dioxide is used by producers during photosynthesis and is released during cellular respiration.

Front

What is a hydrophobic molecule?

Back

A hydrophobic molecule is one that does not mix well with water, such as lipids.
