Question

Which step is called gateway step/link reaction in aerobic respiration?

Answer 1

Answer:

During aerobic respiration, pyruvic acid which is formed during glycolysis enters the mitochondrial matrix. It undergoes oxidative decarboxylation to produce CO

2

and NADH. The product combines with sulfur-containing co-enzyme A to form acetyl CoA. This reaction is catalyzed by an enzyme complex pyruvate dehydrogenase. This step is called link reaction or gateway step as it links glycolysis with Krebs' cycle

.Pyruvicacid+COA+NAD +Mg 2+Pyruvatedehydrogenase AcetylCoA+CO +NADH+H+

So the correct answer is 'Formation of acetyl coenzyme A'.

Answer 2

Answer:

1) glycolysis

2)formation of acetyl coenzyme A

3)citric acid formation

4)ETS terminal oxidation
