Energy Transformations

Part A

Which of these is exhibiting kinetic energy?

	an archer with a flexed bow
	a space station orbiting Earth
	a rock on a mountain ledge
	a person sitting on a couch while watching TV
	the high-energy phosphate bonds of a molecule of ATP

Correct

Kinetic energy is energy of motion.

Part B

"Conservation of energy" refers to the fact that _____.

	if you conserve energy you will not be as tired
	the entropy of the universe is always increasing
	energy cannot be created or destroyed but can be converted from one form to another
	the net amount of disorder is always increasing
	no chemical reaction is 100 percent efficient

Correct

This is what is meant by conservation of energy.

Part C

Chemical energy is a form of _____ energy.

	entropic
	motion
	heat
	potential
	kinetic

Correct

Chemical energy is a form of stored energy.

Part D

In your body, what process converts the chemical energy found in glucose into the chemical energy found in ATP?

	anabolism
	redox
	cellular respiration
	digestion
	potentiation

Correct

This is the name given to the process by which the body converts food energy to energy stored in ATP.

Part E

Which of these are by-products of cellular respiration?

	ATP, carbon dioxide, and water
	glucose, carbon dioxide, and water
	carbon dioxide and water
	heat, carbon dioxide, and water
	ATP and carbon dioxide

Correct

These are the by-products of cellular respiration.
