Question

Which of the following are NOT functions of a triglyceride?

a) to regulate body chemistry by speeding up chemical reactions
b) to provide long term energy
c) to provide insulation
d) to provide the body with a quick energy source
e) to store energy in the body

Answer 1

Triglycerides do not function to speed up chemical reactions; that's a role of enzymes. Their functions include long-term energy storage, insulation, and energy provision for prolonged activities.

Step-by-step explanation:

Among the listed potential functions of a triglyceride, the one that is NOT a function of triglycerides is 'to regulate body chemistry by speeding up chemical reactions.' This is more characteristic of enzymes rather than triglycerides.

Triglycerides serve mainly as a form of long-term energy storage in animals, including humans, and are particularly important when the body is at rest or engaged in slow, prolonged physical activity.

They are also critical for insulation, protecting body's bones and internal organs, and storing energy in the body. The breakdown of triglycerides involves converting them into acetyl CoA, which then enters the citric acid cycle for energy production.
