There are two photosystems associated with photosynthesis, which have been named in order of their discovery as
Correct answer: B. PS-I and PS-II
- A. P680 and P700
- B. PS-I and PS-II
- C. PS-II and PS-I
- D. Photo system alpha and photo system beta
Explanation
The correct answer is PS-I and PS-II. Photosystem I (PS-I) was discovered before Photosystem II (PS-II), which is why they are named in this sequential order of their discovery. Even though Photosystem II functions first in the linear electron flow during the light-dependent reactions of photosynthesis, it was identified after Photosystem I.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
