When the body does not have enough glucose, fat cannot be completely burned for energy. What happens to fat oxidation without adequate glucose?
A) Fat oxidation goes to completion because it draws on the body's store of glucagon.
B) Fat oxidation stops prematurely, and fat is excreted in the body's waste.
C) Fat oxidation goes to completion because it forces the body into ketosis.
D) Fat oxidation stops prematurely at the intermediate step of ketone formation.

Feedback:
Fat normally supplies about half of the body's energy requirement. Yet glucose fragments are needed to efficiently and completely burn fat for energy. Without adequate glucose, fat oxidation prematurely stops at the intermediate step of ketone body formation. Fat oxidation does not go into completion without adequate glucose. Fat oxidation does not draw on the glucagon stores of the body. Fat oxidation does not stop prematurely and fat is excreted in the body's waste.
