Photosynthesis and Respiration Review

What is the equation for aerobic respiration?

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

• C₆H₁₂O₆ + 3O₂ → 3CO₂ + 3H₂O + 2ATP

• C₆H₁₂O₆ + 2O₂ → 2CO₂ + 2H₂O + 4ATP

• C₆H₁₂O₆ + 6O₂ → 2CO₂ + 2H₂O + 36ATP

What are the main reactants of cellular respiration?

• Glucose and oxygen.

• Carbon dioxide and water.

• Glucose and carbon dioxide.

• Oxygen and nitrogen.

What is the relationship between photosynthesis and respiration?

• Photosynthesis produces glucose and oxygen, which are used in respiration to produce energy, while respiration releases carbon dioxide and water, which are used in photosynthesis.

• Photosynthesis occurs only in plants, while respiration occurs in both plants and animals.

• Photosynthesis and respiration are completely independent processes with no relationship.

• Photosynthesis is a process that occurs at night, while respiration occurs during the day.

What is cellular respiration?

• A process that converts sunlight into glucose

• A method of photosynthesis in plants

• The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

• A way for cells to store energy for later use.

What type of organisms perform photosynthesis?

• Animals

• Plants, algae, and some bacteria.

• Fungi

• Viruses

What is the byproduct of anaerobic respiration in humans?

• Carbon dioxide

• Ethanol

• Lactic acid

• Oxygen

What happens to breathing rate during exercise?

• Breathing rate decreases to conserve energy.

• Breathing rate remains the same regardless of activity.

• Breathing rate increases to supply more oxygen to the muscles and remove carbon dioxide.

• Breathing rate fluctuates randomly during exercise.

What is the significance of oxygen in respiration?

• Oxygen is a byproduct of anaerobic respiration.

• Oxygen is essential for aerobic respiration as it acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

• Oxygen is not required for any form of respiration.

• Oxygen helps in the breakdown of glucose without producing energy.

What is the role of chlorophyll in photosynthesis?

• Chlorophyll is a type of carbohydrate produced during photosynthesis.

• Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

• Chlorophyll helps in the respiration process of plants.

• Chlorophyll is responsible for the transport of nutrients in plants.

What are the main products of photosynthesis?

• Glucose and oxygen.

• Carbon dioxide and water.

• Nitrogen and glucose.

• Oxygen and nitrogen.
