Question

Reducing power generated during light reaction is used during formation of:
A) 3-phosphoglyceraldehyde from RuBP
B) Sucrose from triose phosphate
C) Glyceraldehyde 3-phosphate from 3-phosphoglycerate
D) RuBP from triose phosphate

Answer 1

Hint:The light reaction produces assimilatory energy in the formation of ATP and NADPH, which is utilized in the combination of carbohydrates in the dark reaction. It is utilized during the renewal period of the Calvin cycle.

Complete answer:
Before we find out the correct option let us know a little about light reaction. The light-dependent effects that utilise light energy to produce two particles required for the next step of photosynthesis: the energy storage particle ATP and the controlled particle vector NADPH. In plants, the light reactions take spot in the thylakoid layers of organelles termed chloroplasts.

During reformation 12 mol of 3-phosphoglycerate are phosphorylated by 12 mol of ATP to produce 12 mol of 1,3-bisphosphoglycerate in the appearance of catalyst phosphoglycerate kinase.
The particles of ATP get transformed to ADP. 12 mol of 1,3-bisphosphoglycerate is decreased to 12 mol of 3-phosphoglyceraldehyde in the appearance of coenzyme NADPH. The result is catalyzed by the catalyst triose phosphate dehydrogenase Chemical phosphate is delivered.Therefore, this is the correct answer.

As option C is correct, therefore option A, B and D are incorrect.

Additional Information: The overall purpose of light-dependent reactions, the first step of photosynthesis, is to convert solar power into chemical power in the formation of NADPH and ATP, which are utilized in light-independent effects and feed the collection of sugar particles.

Thus, the correct answer is option (C) Glyceraldehyde 3-phosphate from 3-phosphoglycerate.

Note:Glyceraldehyde 3-phosphate also recognised as triose phosphate or 3-phosphoglyceraldehyde and abbreviated as GA3P, GADP, G3P, GALP, TP, GAP or PGAL, is the metabolite that happens as an intermediate in the various central metabolism of all bions.
