Question

Ketoacidosis is

• A. a result of breakdown of fat.
• B. accumulation of uric acid in the blood.
• C. utilization of carbohydrates to provide energy.
• D. Sufficient amount of insulin released into the blood.

Hint:

A classic symptom of diabetic ketoacidosis is fruity-smelling breath. This is caused by the body releasing acetone (a volatile ketone body) through the lungs as it tries to clear the excess acid.

Answer 1

The Correct Option is A

Step 1: Understanding Cellular Energy Pathways:
The body's cells rely on glucose as their primary source of energy, requiring insulin to absorb glucose from the bloodstream.

Step 2: The Mechanism of Ketoacidosis:
When there is a severe lack of insulin (as in untreated Type I diabetes) or during prolonged starvation:

• Cells cannot absorb glucose from the blood, leaving them starved of energy.
• To survive, the body begins breaking down stored fats rapidly for energy.
• This rapid fat metabolism produces acidic byproducts called ketone bodies (such as acetoacetate and beta-hydroxybutyrate) in the liver.
• When ketones build up faster than the body can use or excrete them, they accumulate in the bloodstream, lowering blood pH and leading to a life-threatening medical emergency known as ketoacidosis (or Diabetic Ketoacidosis - DKA).

Step 3: Evaluating the Options:

• Option A: Correctly identifies ketoacidosis as the result of rapid fat breakdown.
• Option B: Uric acid accumulation causes Gout, not ketoacidosis.
• Option C: Utilizing carbohydrates cleanly produces carbon dioxide and water, and does not produce ketones.
• Option D: Adequate insulin levels prevent the rapid breakdown of fat, stopping ketone production.

Therefore, option (A) is the correct answer.
