Acetyl CoA is common to respiration mediated breakdown of fats, carbohydrates and proteins. Fats are broken down to fatty acid and glycerol and again fatty acid degraded to acetyl Co - A . Protein first degraded by proteases to indiviual amino acids which deaminated to pyruric acid and further decarboxylised to acetyl Co- A

Answer:
The metabolite that is common to the respiration-mediated breakdown of fats, carbohydrates, and proteins is Acetyl CoA.
Explanation:
The process of respiration involves the breakdown of complex molecules such as fats, carbohydrates, and proteins to produce energy in the form of ATP. These molecules are broken down into smaller units that can enter the respiratory pathway and be oxidized to release energy.
1. Fats:
Fats are broken down into glycerol and fatty acids through a process called lipolysis. The fatty acids are further broken down in a process known as beta-oxidation to produce Acetyl CoA. Acetyl CoA then enters the citric acid cycle (also known as the Krebs cycle) to generate ATP.
2. Carbohydrates:
Carbohydrates are broken down into glucose through processes such as glycolysis and glycogenolysis. Glucose is then converted to pyruvic acid through glycolysis. Pyruvic acid is further converted to Acetyl CoA through a process called pyruvate decarboxylation. Acetyl CoA then enters the citric acid cycle to produce ATP.
3. Proteins:
Proteins are broken down into amino acids through a process called proteolysis. The amino acids are then converted to various intermediates of the citric acid cycle. Some of these intermediates can be converted to Acetyl CoA and enter the citric acid cycle to generate ATP.
Conclusion:
In summary, Acetyl CoA is the common metabolite in the respiration-mediated breakdown of fats, carbohydrates, and proteins. It serves as a key molecule that enters the citric acid cycle to produce ATP, the energy currency of the cell.

Acetyl Co-A is common to respiration mediated breakdown of fats, carbohydrates and proteins. Glucose and fructose are phosphorylated to give rise to glucose-6-phosphate by the activity of the enzyme hexokinase.
Glucose-6-phosphate then converts into fructose 6 phosphate and further to fructose 1-6-bisphosphate. Pyruvic acid is the end product of glycolysis.
