Question

which of the following is the first stable products of photosynthesis in maize? PGA , PGAL, PEPA, OAA

Answer 1

First product which is stable of photosynthesis in maize is phospho glyceric acid (PGA).

Explanation:

PGA, also known as phosphoglycerate, is a carbon molecule (three) that is formed when $CO_2$ is added on ribulose biphosphate. This happens during the dark reaction of photosynthesis also known as the Calvin cycle. PGA is then converted to Phosphoglyceraldehyde (PGAL), using Adenosine triphosphate (ATP). Eventually, some PGAL is converted to glucose, which helps in nourishement of plant.
