Question

75) Oxygen is required for which of the following enzymatic pathways A) Oxidative phosphorylation B) Calvin Cycle C ) Glycolysis D) Neither of these

Answer 1

OXIDATIVE PHOSPHORYLATION REQUIRES OXYGEN AS THE ELECTRONS GENERATED BY ELECTRON TRANSPORT CHAIN ARE ACCEPTED BY OXYGEN AND ALONG WITH HYDROGEN ION IT FORM WATER. CALVIN CYCLE IS THE DARK REACTION OCCURING IN ALL PHOTOSYNTHETIC PLANT, IT FIX THE CO2 INTO GLUCOSE WITH EXPENDITURE OF ENERGY. GLYCOLYSIS IS THE COMMON STEP FOR OXIDATION OF GLUCOSE AND IT DOES NOT REQUIRE OXYGEN.
