Question 5

Read the following scenario to answer the following question(s) .
Cellular respiration converts the energy of fuel molecules to a form of energy that a cell can use to perform work. In an average day, most adult humans need to consume about 2,000 Calories to maintain their health. However, the exact amount of dietary Calories a person needs depends upon many factors, including the person's age, physical activity, size, and health. Foods that we consume vary greatly in their nutritional content and quality. A large hard-boiled egg, for example, has about 75 dietary Calories and contains about 70% of our recommended daily intake of cholesterol.
-Molecules that come from the food we eat provide energy for the amazing work that goes on inside of our cells.This energy,stored inside of our food,is a form of ______.

Accepted Answer

A)   potential energy called chemical energy
B)   potential energy called entropy
C)   kinetic energy called heat
D)   electrical energy called heat
