Photosynthesis & Cellular Respiration

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, using carbon dioxide and water.

Front

What is cellular respiration?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Front

What is the difference between autotrophic and heterotrophic organisms?

Back

Autotrophic organisms produce their own food (e.g., plants via photosynthesis), while heterotrophic organisms obtain energy by consuming other organisms (e.g., animals).

Front

What organelle is responsible for photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs.

Front

What is glucose and why is it important?

Back

Glucose (C6H12O6) is a simple sugar that serves as a primary energy source for cells during cellular respiration.

Front

What is the significance of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What are the byproducts of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide (CO2) and water (H2O).
