00:01 Hello everyone, in this question we have been asked that a long distance runner is training and part of the training requires a multiple sets of 800 meter run in order to increase the stamina.

00:15 So, we have to explain.

00:18 So, basically energy generation is by the tricarbonyl acetic cycle that is enhanced under these conditions.

00:25 So, we need to explain the answer and on what basis we will rule out the other choices.

00:32 So, here option a says that the allosteric inhibitor of the isocyte dehydrogenase by increase nadh.

00:42 So, that is incorrect because then only because here the exercise is taking place.

00:49 Then option b says allosteric activation of the tumor is by increase avp.

00:54 So, by increase adp basically they are doing the production of atp, but we want atp not we want to produce it.

01:04 So, here we want the hydrolysis of atp not the phosphorylation of the adp.

01:08 And the option c says a rapid decrease in the concentration of 4 -carbon intermediate.

01:13 So, that is also incorrect.

01:15 And option d says product inhibition of citrate synthesis.

01:19 So, that is incorrect because then the cycle will not take place.

01:22 Then option e says stimulation of the flux to a number of enzymes by decrease nadh, nad plus ratio.

01:31 So, basically during the aerobic exercise the muscle needs to generate atp by the oxidative phosphorylation.

01:41 So, for this to occur the nadh level will decrease because then it will be oxidized to the nad plus...
