Q.
Consider the first reaction of $TCA$ cycle.
What is true about compound $A$?
Respiration in Plants
Solution:
The $TCA$ cycle starts with the condensation of acetyl group with oxaloacetic acid and water to yield citric acid. It is a tricarboxylic $6$-carbon compound and undergoes reorganisation in the presence of iron containing enzyme aconitase first forming cis aconitate and releasing water.
Citrate $\xrightarrow[Fe^{+2}] {\text{Aconitase}}$ $cis$ - aconitate $+ H_2O$
