Macromolecules & Carbon Cycle Review

Front

What is a macromolecule?

Back

A large molecule composed of thousands of atoms, typically organized into complex structures. Examples include proteins, lipids, carbohydrates, and nucleic acids.

Front

What are the four main types of macromolecules?

Back

Proteins, lipids, carbohydrates, and nucleic acids.

Front

What is a lipid?

Back

A type of macromolecule that is hydrophobic and does not dissolve in water. Examples include fats, oils, and triglycerides.

Front

What is a carbohydrate?

Back

A macromolecule made up of sugar molecules, which provide energy and structural support. Examples include glucose, starch, and cellulose.

Front

What is the primary function of proteins?

Back

Proteins serve various functions including catalyzing biochemical reactions (enzymes), providing structure, and facilitating communication within and between cells.

Front

What is photosynthesis?

Back

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

The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the carbon cycle?

Back

The series of processes by which carbon compounds are interconverted in the environment, including photosynthesis, respiration, decomposition, and combustion.

Front

What is an example of a triglyceride?

Back

Fats and oils that are composed of glycerol and three fatty acids.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the atmosphere and soil.
