Unit 2 Exam Review

Front

What is the role of carbon in living organisms?

Back

Carbon is a fundamental building block of life, found in all organic molecules, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What are the main products of aerobic cellular respiration?

Back

The main products of aerobic cellular respiration are carbon dioxide (CO2) and water (H2O).

Front

Write the equation for cellular respiration.

Back

The equation for cellular respiration is: 6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy.

Front

During which stage of photosynthesis do plants use carbon dioxide to produce glucose?

Back

Plants use carbon dioxide during the Calvin Cycle to produce glucose.

Front

What is global warming?

Back

Global warming refers to the increase in the average temperatures on Earth due to the accumulation of greenhouse gases in the atmosphere.

Front

What is the significance of the Calvin Cycle in photosynthesis?

Back

The Calvin Cycle is significant because it is the stage where carbon dioxide is fixed into organic molecules, ultimately leading to the production of glucose.

Front

How does aerobic respiration differ from anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) compared to anaerobic respiration, which occurs without oxygen and produces less energy.

Front

What are greenhouse gases, and why are they important?

Back

Greenhouse gases, such as CO2 and methane, trap heat in the atmosphere, contributing to the greenhouse effect and global warming.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What is the importance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is essential for photosynthesis in plants and plays a crucial role in regulating Earth's temperature through the greenhouse effect.
