1.	Consider the first reaction of TCA cycle. Acetyl `CoA + OA A +H_(2)O overset("Citrate")underset("synthase")rarr A + CoA` What is true about compound A?A. First product of TCA cycleB. Tricarboxylic acid and six carbon compoundC. It undergoes reorganisation in the presence of enzyme aconitase to form cis-aconitateD. All of these
Answer» Correct Answer - D The TCA cycle starts with the condensation of acetyl group with oxaloacetic acid and water to yield citric acid. It is tricarboxylic 6-carbon compound and undergoes reorganisation in the presence of iron containing enzyme aconitase first forming cis aconitrate and releasing water `"Citrate" underset(Fe^(2+))overset("Aconitase")(hArr) cis-"aconitate" +H_(2)O`

In glycolysis, glucose splits into compounds which areA. 5-CB. 4-CC. 2-CD. 3-C
Make corrections wherever you find mistake in spellings/words in the following paragraphs :- A. When fats are used in respiration, the RQ is more than unity because fats contain more `O_(2)` and require relatively less amount of `O_(2)` for oxidation. B. The most important energy carrier is ATP. This energy rich compound is mobile and can pass from one cell into another. C.
