Question

1. how are photosynthesis and cellular respiration related?

a. the products of one are the reactants of the other. b. both processes release carbon dioxide.
c. both occur only in plants. d. photosynthesis breaks down glucose, and respiration builds it.

1. during photosynthesis, energy is stored in glucose. during cellular respiration, that energy is —

a. used to make more chlorophyll b. converted into atp for the cell to use
c. turned into sunlight d. destroyed

1. which statement best describes the energy flow between plants and animals?

a. animals convert sunlight directly into chemical energy.
b. both plants and animals produce their own glucose.
c. plants and animals use photosynthesis to release atp.
d. plants use sunlight to make food, and animals use that food to release energy

Explanation:

• Question 4:
• Photosynthesis equation: \(6CO_2 + 6H_2O+light

ightarrow C_6H_{12}O_6 + 6O_2\)

• Cellular respiration equation: \(C_6H_{12}O_6+6O_2

ightarrow 6CO_2 + 6H_2O+energy\)

• So, the products of one (e.g., \(O_2\) from photosynthesis) are reactants of the other (cellular respiration).
• Question 5:
• In cellular respiration, the energy stored in glucose (\(C_6H_{12}O_6\)) is used to produce ATP (adenosine - tri - phosphate), which is the energy currency of the cell.
• Question 6:
• Plants use sunlight in photosynthesis to make glucose (\(C_6H_{12}O_6\)). Animals consume plants (or plant - eating animals) and break down the glucose (through cellular respiration) to release energy.

Answer:

1. A. The products of one are the reactants of the other.
2. B. converted into ATP for the cell to use
3. D. Plants use sunlight to make food, and animals use that food to release energy
