PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Molecular oxygen is produced during-
A
the Calvin Cycle
B
the light reactions of photosynthesis
C
glycolysis
D
the electron transfer chain
Explanation: 

Detailed explanation-1: -Yes, oxygen is produced in the light reaction of photosynthesis in lumen thylakoid by the photolysis of water.

Detailed explanation-2: -Essentially, oxygen is a waste product of the light reactions of photosynthesis. It is a ‘’leftover” from a necessary part of the process. All the oxygen that is necessary to maintain most forms of life just happens to come about during this process.

Detailed explanation-3: -The reactions that generate molecular oxygen that take place during photosynthesis occur in the chloroplast. Specifically, they occur within the thylakoids of the chloroplasts.

Detailed explanation-4: -The by-product of the water-splitting reaction is molecular oxygen.

Detailed explanation-5: -Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.
