Which of the following forms of energy is not correctly matched?

• A. Kinetic energy fat molecules
• B. Kinetic energy: movement of muscles
• C. Chemical energy: glucose
• D. Potential energy ATP

Answer 1

The correct option is A Kinetic energy fat molecules

Fats typically provide more than half of the body's energy needs. Fat from food is broken down into fatty acids, which can travel in the blood and be captured by hungry cells. Fatty acids that aren't needed right away are packaged in bundles called triglycerides and stored in fat cells, which have unlimited capacity. Fat is the body's most concentrated source of energy, providing more than twice as much potential energy as carbohydrate or protein (9 calories per gram versus 4 calories each per gram).

Kinetic energy comes into play when there is motion (for e.g. muscles) while fats are rather part of energy requirement during the static state of the body. Hence, fat molecules rather provide potential energy.

So, the correct option is 'Kinetic energy fat molecules'.
