Question

which part of photosynthesis uses carbon dioxide?
a light reactions
b calvin cycle
c thylakoid
d krebs cycle

Explanation:

• Light reactions: These use light energy to produce ATP and NADPH, not carbon dioxide.
• Calvin cycle: This is the part of photosynthesis where carbon dioxide is fixed and used to make glucose.
• Thylakoid: It is a structure in the chloroplast where light reactions occur, not a process that uses carbon dioxide.
• Krebs cycle: This is part of cellular respiration, not photosynthesis.

Answer:

B. Calvin cycle
