What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the two main types of cellular respiration?

Back

The two main types of cellular respiration are aerobic respiration (requires oxygen) and anaerobic respiration (does not require oxygen).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment in plants that absorbs light energy, primarily from the blue and red wavelengths, and reflects green light.

Front

What is the equation for photosynthesis?

Back

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

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the difference between ADP and ATP?

Back

ADP (adenosine diphosphate) has two phosphate groups, while ATP has three. ATP can release energy when it loses a phosphate group to become ADP.

Front

What is the significance of the conservation of matter in cellular processes?

Back

The conservation of matter states that matter cannot be created or destroyed, meaning that during cellular processes, the total mass of reactants equals the total mass of products.

Front

How do plants and animals obtain energy?

Back

Plants obtain energy through photosynthesis, while animals obtain energy through cellular respiration.

Front

What is the byproduct of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide and water.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.
