Question

determine whether each item belongs to photosynthesis, cellular respiration, or both.
performed by all organisms
produces atp energy
takes place in the chloroplast
performed by producers / autotrophs
breaks down glucose using oxygen
transforms energy
requires solar (light) energy

Explanation:

• Performed by all organisms: Cellular respiration occurs in all organisms (plants, animals, fungi, etc.) as it is the process by which they release energy from food. Photosynthesis only occurs in autotrophs (plants, some bacteria, etc.).
• Produces ATP energy: Both photosynthesis (in the light - dependent reactions) and cellular respiration (in glycolysis, Krebs cycle, and electron transport chain) produce ATP.
• Takes place in the chloroplast: Chloroplasts are the organelles where photosynthesis occurs. Cellular respiration occurs in the mitochondria (for aerobic respiration in eukaryotes) and the cytoplasm (for glycolysis).
• Performed by producers/autotrophs: Producers/autotrophs are the organisms that perform photosynthesis to make their own food. While they also perform cellular respiration, the key characteristic for this item is that it is specific to photosynthesis - performing organisms.
• Breaks down glucose using oxygen: This is the description of aerobic cellular respiration (the overall equation is \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+\text{energy}\)). Photosynthesis builds glucose (\(6CO_2+6H_2O+\text{light energy}
ightarrow C_6H_{12}O_6 + 6O_2\)).

• Transforms energy: Photosynthesis transforms light energy into chemical energy (stored in glucose). Cellular respiration transforms the chemical energy in glucose (and other organic molecules) into ATP (a more usable form of chemical energy). So both processes transform energy.
• Requires solar (light) energy: Only photosynthesis requires solar (light) energy as it is used in the light - dependent reactions to split water and produce ATP and NADPH.

Answer:

• Performed by all organisms: Cellular Respiration
• Produces ATP energy: Both
• Takes place in the chloroplast: Photosynthesis
• Performed by producers/autotrophs: Photosynthesis
• Breaks down glucose using oxygen: Cellular Respiration
• Transforms energy: Both
• Requires solar (light) energy: Photosynthesis
