Biology: Concepts and Connections, 5e (Campbell) Chapter 5: The Working Cell 1) Many of the enzymes that control a firefly's ability to produce light energy from chemical energy are located A) in membranes. B) in the nucleus. C) within chloroplasts. D) outside of cells. E) within mitochondria. Answer: A Topic: Introduction Skill: Factual Recall 2) Kinetic energy differs from chemical energy in that A) kinetic energy is stored energy that has the potential to do work, and chemical energy is the energy of movement. B) kinetic energy depends on the movement of atoms, whereas chemical energy depends on the movement of molecules. C) kinetic energy can be converted into various forms of energy, whereas chemical energy can only be converted into heat. D) kinetic energy is the energy of a moving object, whereas chemical energy is the potential energy of molecules. E) chemical energy is a particular form of kinetic energy.
