YOUR ANSWER SHOULD BE SOMETHING LIKE THIS (perhaps a bit less detailed): Acetyl-CoA that is produced in excess of the amount that can be metabolized in the citric acid cycle results in a high concentration of acetyl-CoA. When this occurs, acetyl-CoA reacts with other acetyl-CoA to produce the three compounds that are referred to as ketone bodies. This process is referred to as ketogenesis. Ketone bodies are produced as shown in the reactions below. When individuals diet, they begin to metabolize the triglycerides that are stored in fat cells. This leads to ketogenesis.

YOUR ANSWER SHOULD BE SOMETHING LIKE THIS (perhaps a bit less detailed):
Acetyl-CoA that is produced in excess of the amount that can be metabolized in the citric acid cycle results in a high
concentration of acetyl-CoA. When this occurs, acetyl-CoA reacts with other acetyl-CoA to produce the three
compounds that are referred to as ketone bodies. This process is referred to as ketogenesis. Ketone bodies are produced
as shown in the reactions below. When individuals diet, they begin to metabolize the triglycerides that are stored in fat
cells. This leads to ketogenesis.

In cases of starvation, poorly treated diabetes, and conditions
related to alcoholic binge drinking, the cells cannot get glucose
and extremely high rates of fatty acid catabolism results in
dangerous, and even fatal levels of ketone bodies. ß-
hydroxybutyric acid and acetoacetic acid (the acid forms of ß-
hydroxybutyrate and acetoacetate, respectively) have significant
acid strength. Their production results in a higher concentration
of H3O+, which can overcome the blood's buffering capacity.
When this occurs, the blood becomes acidic. When blood pH is
less than the normal range (7.35-7.45), the condition is called
acidosis. When acidosis is caused by excess ketone bodies, the
condition is called ketoacidosis.
