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. a d is atp. b a is sunlight. c b is h₂o. d f is co₂ + h₂o. e c is co₂ + c₆h₁₂o₆.

Explanation:

Cellular respiration in mitochondria uses oxygen and glucose to produce carbon - dioxide, water, and ATP. Photosynthesis uses carbon - dioxide and water to produce glucose and oxygen. Since the diagram is about the relationship between photosynthesis and cellular respiration and the role of mitochondria in cellular respiration:

• ATP is a product of cellular respiration in mitochondria, so D could potentially be ATP.
• Sunlight is not directly related to the inputs and outputs of the mitochondrial reactions shown, so A being sunlight is incorrect.
• Water ($H_2O$) is a product of cellular respiration in mitochondria, so B could be $H_2O$.
• Carbon - dioxide and water ($CO_2 + H_2O$) are products of cellular respiration, so F being $CO_2 + H_2O$ is correct.
• Glucose ($C_6H_{12}O_6$) is broken down in cellular respiration and carbon - dioxide is a product, but the combination $CO_2 + C_6H_{12}O_6$ is incorrect as an input or output for this mitochondrial process.

Answer:

A. D is ATP.
C. B is $H_2O$.
D. F is $CO_2 + H_2O$.
