Question

114. Name the enzyme which changes its characteri-
stics with change in concentration of O2
1) PEP-Carboxylase
2) Hexokinaseh o
3) Rubis-co
4) Pyruvic dehydrogenase​

Answer 1

Answer:

2

Explanation:

2) Hexokinaseh o enzyme which changes its characteri-

stics with change in concentration of O2

Answer 2

(3) Rubis-co is the enzyme which changes its characteristics with change in concentration of $O_{2}$

Explanation:

• An oxygen molecule can connect securely at the place meant to bind carbon dioxide in rubisco. The oxygen is subsequently attached to the sugar chain by Rubisco, resulting in a defective oxygenated product.
• To rectify the issue, the plant cell must go through an expensive series of salvage processes. Depending on the environmental circumstances, Rubisco can bind to either carbon dioxide or oxygen.
• At high temperatures and a low carbon dioxide-to-oxygen ratio, binding to oxygen and the commencement of photorespiration are preferred.
