Unit 1 – Concept 7 Photosynthesis & Respiration
SB3A. Explain the cycling of energy through the processes of photosynthesis and
respiration.
1. Plants undergo both photosynthesis and respiration. Which statement correctly compares
photosynthesis with respiration?
A. Photosynthesis releases stored energy, while respiration stores energy.
B. Photosynthesis stores energy, while respiration releases stored energy.
C. Neither photosynthesis nor respiration require water.
D. Both photosynthesis and respiration require sunlight.
2. How does the amount of energy resulting from fermentation compare with that of aerobic
respiration?
A. Aerobic respiration results in less energy.
B. Aerobic respiration results in more energy.
C. Each process results in equal amounts of energy.
D. Each process results in variable amounts of energy.
3. Which statement best compares aerobic and anaerobic respiration?
A. Less ATP is generated during anaerobic respiration than during aerobic respiration.
B. More water is generated during anaerobic respiration than during aerobic respiration.
C. More oxygen is generated during anaerobic respiration than during aerobic respiration.
D. Less lactic acid is generated during anaerobic respiration than during aerobic
respiration.
4.
5. Which of these statements best explains the process of energy conversion that takes place in
the mitochondria?
F Energy is required for carbon dioxide molecules to form six-carbon sugar molecules.
G Water molecules and radiant energy are necessary for anaerobic respiration to take
place.
H Oxygen molecules release energy in the form of heat during combustion reactions.
J The energy in the bonds of glucose molecules is transferred to the phosphate bonds in
ATP.
6. Which of the following correctly describes how a diagram of cellular respiration would differ
from a diagram of photosynthesis?
A. The cellular-respiration diagram would show electromagnetic waves as the final
product.
B. The cellular-respiration diagram would show glucose as the main source of energy.
C. The cellular-respiration diagram would show energy stored in large protein molecules.
D. The cellular-respiration diagram would show water as the main source of chemical
energy.
