Answer:
Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate
Explanation:
Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.
The fundamental unit of the organism, the cell contains various organelles with specialized functions and roles. The plasma or cell membrane separates the cell structure.
<h3>What is plasma or cell membrane?</h3>
Cell or the plasma membrane is the cell structure that is seen in the cells that separate the outer cell surroundings from the inner environment of the cell.
They allow the semipermeable passage and transportation of the substances in and out of the cell and are made up of lipid bilayer. It protects the cell from the invasion of bacteria and other microbes.
Therefore, option A. plasma or cell membrane separates the inner and the outer environment of the cell.

Answer:
They take glucose and break the glucose into ATP molecules and proton energy, essential for cellular respiration to continue.
