Cell Respiration and Photosynthesis QuizLE

What is the primary function of cell respiration?

• To produce glucose for energy storage

• To synthesize proteins for cell growth

• To regulate cell division

• To produce ATP, the primary energy source for cellular activities.

Where does photosynthesis take place in a plant cell?

• Nucleus

• Cell membrane

• Mitochondria

• Chloroplasts

What are the products of cell respiration?

• Lactic acid, ethanol, and acetic acid

• Glucose, oxygen, and nitrogen

• Protein, fat, and vitamins

• ATP, carbon dioxide, and water

What are the reactants of photosynthesis?

• carbon dioxide and water

• oxygen and glucose

• hydrogen and carbon monoxide

• nitrogen and sunlight

What is the chemical equation for cell respiration?

• C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O + ATP

• C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O

• 6CO₂ + 6H₂O + ATP -> C₆H₁₂O₆ + 6O₂

• H₂O + CO₂ -> C₆H₁₂O₆ + 6O₂

Describe the process of photosynthesis.

• Photosynthesis is the process of converting glucose into oxygen and water using sunlight.

• Photosynthesis is the process of breaking down food into energy using sunlight, carbon dioxide, and water.

• Plants use sunlight to convert oxygen and water into carbon dioxide and glucose.

• Green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, carbon dioxide, and water.

What is the role of chlorophyll in photosynthesis?

• Converts chemical energy into light energy for the plant

• Absorbs light energy and converts it into chemical energy

• Helps in the breakdown of glucose to release energy

• Reflects light energy and prevents it from reaching the plant

Differentiate between aerobic and anaerobic respiration.

• Aerobic respiration requires carbon dioxide, while anaerobic respiration requires oxygen.

• Aerobic respiration requires oxygen, while anaerobic respiration does not require oxygen.

• Aerobic respiration occurs in the absence of glucose, while anaerobic respiration occurs in the presence of glucose.

• Aerobic respiration produces more ATP than anaerobic respiration.

Explain how cell respiration and photosynthesis are interconnected.

• They are completely independent processes with no connection

• Cell respiration produces oxygen while photosynthesis produces carbon dioxide

• Cell respiration occurs in plants while photosynthesis occurs in animals

• The exchange of gases and the use of products from one process as reactants in the other process.

What is the role of sunlight in photosynthesis?

• It provides the heat energy required for photosynthesis

• It provides the light energy that is converted into chemical energy

• It provides the oxygen required for photosynthesis

• It provides the carbon dioxide required for photosynthesis
