Expert Solution
Step 1

Tricarboxylic acid cycle is also referred to as citric acid cycle and is an important step in the catabolic reactions. The acetyl CoA produced from the oxidation of carbohydrates, fats and proteins enter the cycle and produces energy in the from of ATP by substrate-level phosphorylation. During the TCA cycle, reducing equivalents are also produced that are used to harvest energy during the electron transport chain. 

Compounds that have non-superimposable mirror images are referred to as chiral compounds. Those compounds that have superimposable mirror images are referred to as non-chiral or achiral.
