Respiration in Plants · Biology · IAT (IISER)

A cell suspension of actively respiring mitochondria is treated with either chemical X (experiment 1) or chemical Y (experiment 2), or left untreated (experiment 3 ).

Chemical X selectively inhibits electron transport from Complex I to ubiquinone, while chemical Y selectively inhibits electron transport from Complex III to cytochrome C.

Which one of the following options represents the correct order of relative number of ATP synthesised in mitochondria?

Shown below are some of the reactions that occur in the metabolic pathway leading to complete oxidation of glucose during aerobic respiration.

i. Pyruvate $\rightarrow$ Acetyl CoA

ii. Dihydroxy acetone phosphate $\rightarrow$ Glyceraldehyde-3-phosphate

iii. Oxaloacetate $\rightarrow$ Citrate

iv. Fumarate $\rightarrow$ Malate

Choose the CORRECT sequence of reactions during the complete oxidation of glucose.
