Correct Answers
Metabolism - ANSWERSHow fast a person burns food
A body needs __________ to maintain heartbeat, temperature, breathing, brain activity,
and other basic life requirements. - ANSWERSenergy
The ability to do work; move matter: - ANSWERSEnergy
The total amount of energy in any object is the sum of energy's two forms: -
ANSWERSpotential and kinetic
Stored energy to do work: - ANSWERSPotential energy
Energy being used to do work; any moving object possesses this form of energy: -
ANSWERSKinetic energy
Study of energy transformation: - ANSWERSThermodynamics
1st Law: Energy Conservation: - ANSWERSEnergy cannot be created or destroyed,
although energy can be converted to other forms
Most important energy transformations: - ANSWERSCellular Respiration &
Photosynthesis
Plants and some microorganisms use carbon dioxide, water and the kinetic energy in
sunlight to produce sugars that are assembled into glucose and other carbohydrates: -
ANSWERSPhotosynthesis
Energy-rich glucose molecules change back to carbon dioxide and water, liberating the
energy necessary to power life: - ANSWERSCellular Respiration
2nd Law: - ANSWERSAll energy transformations are inefficient because every reaction
loses some energy to the surroundings as heat.
