Assertion : The first step in TCA cycle is the condensation of pyruvat

1.	Assertion : The first step in TCA cycle is the condensation of pyruvate with oxaloacetic acid and water. Reason : This reaction is catalysed by enzyme pyruvate synthase.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. If both assertion and reason are false
Answer» Correct Answer - d The TCA cycle starts with the condensation of acetyl group with oxaloacetic acid (OAA) and water to yield citric acid. The reaction is catalysed by the enzyme citrate synthetase and a molecule of CoA is released. Acetyl `CoA + OA A + H_(2)O underset("synthetase")overset("Citrate")(rarr) " Citrate " + CoA`

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. Before pyruvic acid enters Krebs cycle, one of the two carbon atoms of pyruvic acid is reduced to carbon dioxide in the reaction called reductive carboxylation. The remaining two carbon pyruvate unit is accepted by coenzyme A to form acetyl coenzyme A.
