Multiple Choice
Which of the following are two other names for the light-independent reactions of photosynthesis?
A
Glycolysis and Fermentation
B
Light Reactions and Photolysis
C
Calvin Cycle and C3 Cycle
D
Krebs Cycle and Electron Transport Chain
Verified step by step guidance
1
Step 1: Begin by understanding the context of the question. The light-independent reactions of photosynthesis are part of the process where plants synthesize glucose using carbon dioxide, ATP, and NADPH produced during the light-dependent reactions.
Step 2: Recall that the light-independent reactions are also known as the Calvin Cycle. This cycle occurs in the stroma of the chloroplast and does not require light directly, hence the name 'light-independent reactions.'
Step 3: Understand that the Calvin Cycle is sometimes referred to as the C3 Cycle because it involves the fixation of carbon dioxide into a three-carbon compound, 3-phosphoglycerate (3-PGA).
Step 4: Eliminate incorrect options by recognizing that glycolysis and fermentation are processes related to cellular respiration, not photosynthesis. Similarly, the Krebs Cycle and Electron Transport Chain are part of cellular respiration, not photosynthesis.
Step 5: Confirm that the correct answer is 'Calvin Cycle and C3 Cycle,' as these are alternative names for the light-independent reactions of photosynthesis.
