8. Energy

Front

What is chlorophyll and why do most plants appear green?

Back

Chlorophyll is a pigment found in plants that absorbs light energy for photosynthesis. Most plants appear green because chlorophyll reflects green light.

Front

Can a cell convert solar energy into chemical energy?

Back

No, cells cannot directly convert solar energy into chemical energy; this process occurs in chloroplasts during photosynthesis.

Front

How do cells use ATP molecules for energy?

Back

Cells use ATP by releasing a 3rd phosphate group, which provides energy for cellular processes.

Front

What is the primary product of cellular respiration?

Back

The primary product of cellular respiration is ATP (adenosine triphosphate), which is used as energy by cells.

Front

Can cells convert chemical food energy into smaller chemical energy compounds?

Back

Yes, cells can convert chemical food energy into smaller chemical energy compounds through metabolic processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.

Front

What role does ATP play in cellular processes?

Back

ATP serves as the main energy currency of the cell, providing energy for various biochemical reactions.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP.
