Question

Explain the steps involved in photorespiration ​

Answer 1

The first step of photorespiration is oxygenation. It is catalyzed by RUBISCO and converts RUBP to one molecule fo 3PGA and one molecule of 2PG, which is a 2 carbon compound with one phosphate group.In normal air at 25°C, a well watered plant fixes oxygen once for every 3 carbon dioxide fixations.

Answer 2

Explanation:

CO2and H2O enter the leaf. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2. The electrons move down to enzymes. Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
