A boulder at the top of a hill contains ________ energy.

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changing ________.

How are membrane transport proteins like enzymes?

Scenario 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. -The amount of dietary Calories in one hard-boiled egg could raise the temperature of ________.

Ten kilocalories are equivalent to ________ calories.

How does the figure below represent the relationship between energy and ATP?
