Cellular Respiration

Question 9 • First Semester Biology

Which characteristics do photosynthesis and cellular respiration have in common?Check all that apply.

Answer
A
Both processes involve a cycle of chemical reactions.
B
Both processes are performed by consumers and producers.
C
Both processes involve energy conversions.
D
Both processes use and produce ATP.
E
Both processes take place in the mitochondrion of a cell.
F
Both processes use an electron transport chain.

Explanation

Both processes include cycles of reactions: photosynthesis has the Calvin cycle, and cellular respiration has the Krebs cycle. Each converts energy, and each both uses ATP in some steps and produces ATP in others. Both also use an electron transport chain. Photosynthesis usually occurs in chloroplasts, not mitochondria, and consumers do not generally perform photosynthesis, so E and B are not shared characteristics.
