Question

alicia is developing a model of photosynthesis and respiration. part of her model includes the inputs and outputs of each process. which of these describes inputs and outputs of alicias model? water is an input for both respiration and for photosynthesis. oxygen is an output for both respiration and for photosynthesis. carbon dioxide is an input for respiration and an output for photosynthesis. glucose is an input for respiration and an output for photosynthesis.

Explanation:

• Photosynthesis:
• Formula: \(6CO_{2}+6H_{2}O + light

ightarrow C_{6}H_{12}O_{6}+6O_{2}\)

• Inputs: Carbon dioxide (\(CO_{2}\)), water (\(H_{2}O\)), light.
• Outputs: Glucose (\(C_{6}H_{12}O_{6}\)), oxygen (\(O_{2}\)).
• Respiration:
• Formula: \(C_{6}H_{12}O_{6}+6O_{2}

ightarrow 6CO_{2}+6H_{2}O+energy\)

• Inputs: Glucose (\(C_{6}H_{12}O_{6}\)), oxygen (\(O_{2}\)).
• Outputs: Carbon dioxide (\(CO_{2}\)), water (\(H_{2}O\)), energy.

• Analyze each option:
• Option 1: Water is an input for photosynthesis but an output for respiration.
• Option 2: Oxygen is an output for photosynthesis but an input for respiration.
• Option 3: Carbon dioxide is an input for photosynthesis and an output for respiration.
• Option 4: Glucose is an output for photosynthesis and an input for respiration.

Answer:

Glucose is an input for respiration and an output for photosynthesis.
