Front

Define biomolecule.

Back

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

Front

What is the role of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy needed for the reaction to occur.

Front

What are carbohydrates made of?

Back

Carbohydrates are made of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is fermentation?

Back

Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen.
