Question

photosynthesis and cellular respiration have a unique relationship in that the products of one are the reactants of the other. evaluate the model provided. the reactants and products are missing from the diagram. select all of the answers below that correctly pair the letter on the diagram with the product or reactant.
d is atp.
a is sunlight.
b is h2o.
f is co2 + h2o.
c is co2 + c6h12o6

Explanation:

• Photosynthesis: Occurs in chloroplasts. Reactants are \(CO_2\), \(H_2O\), and sunlight. Products are \(O_2\) and \(C_6H_{12}O_6\).
• Cellular Respiration: Occurs in mitochondria. Reactants are \(O_2\) and \(C_6H_{12}O_6\). Products are \(CO_2\), \(H_2O\), and ATP.
• Analysis of Options:
• D is ATP: ATP is a product of cellular respiration. So this is correct.
• A is sunlight: Sunlight is a reactant for photosynthesis (occurs in chloroplast). So this is correct.
• B is \(H_2O\): \(H_2O\) is a product of cellular respiration (not a product of photosynthesis). So this is incorrect.
• F is \(CO_2 + H_2O\): \(CO_2\) and \(H_2O\) are products of cellular respiration (which are reactants for photosynthesis). So this is correct.
• C is \(CO_2 + C_6H_{12}O_6\): \(CO_2\) is a reactant for photosynthesis and \(C_6H_{12}O_6\) is a product of photosynthesis. They are not both reactants for any of the processes in the cycle. So this is incorrect.

Answer:

• D is ATP.
• A is sunlight.
• F is \(CO_2 + H_2O\).
