Segment 2 Test

Front

What are the main sources of CO2 into the atmosphere?

Back

Sources of CO2 include human activities, respiration, methane from cows, and deforestation. However, 'overheated molecules' is not a source.

Front

What is ATP also known as?

Back

ATP stands for adenine triphosphate.

Front

What is a carbon sink?

Back

A carbon sink is a carbon reservoir that stores more carbon than it releases.

Front

What is the formula for glucose?

Back

The formula for glucose is C6H12O6.

Front

What biomolecule is represented by nucleic acids?

Back

Nucleic acids are biomolecules that store and transmit genetic information.

Front

What is the role of respiration in the carbon cycle?

Back

Respiration releases CO2 into the atmosphere as organisms convert glucose and oxygen into energy.

Front

What is deforestation and its impact on CO2 levels?

Back

Deforestation is the clearing of forests, which increases CO2 levels by reducing the number of trees that can absorb CO2.

Front

What are the four main types of biomolecules?

Back

The four main types of biomolecules 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 difference between a carbon sink and a carbon source?

Back

A carbon sink absorbs more carbon than it releases, while a carbon source releases more carbon than it absorbs.
