Ketosis Develops in Response To

Question

Ketosis develops in response to
A) glycolysis.
B) hyperglycemia.
C) activation of the urea cycle.
D) rapid and incomplete catabolism of fatty acids.

Accepted Answer

Ketosis develops in response to the rapid and incomplete catabolism of fatty acids, leading to high levels of ketone bodies in the blood. This occurs when carbohydrates are not available or cannot be used as an energy source, such as during periods of low carbohydrate intake, fasting, or in people with uncontrolled diabetes. Glycolysis (A) is a metabolic pathway that breaks down glucose to produce energy, and is not directly related to ketosis. Hyperglycemia (B) is high blood sugar levels, often seen in diabetes, which can lead to complications but does not cause ketosis. The urea cycle (C) is a series of biochemical reactions in the liver that converts ammonia to urea for excretion, and is not related to ketosis.
