Energy, exergonic reactions, and endergonic reactions

Energy is the ability to
	1.	lift objects
	2.	cause a chemical reaction
	3.	destroy or create an object
	4.	cause some sort of change

Chemical energy is energy which
	1.	powers electrical appliances
	2.	is stored in bonds between atoms
	3.	can be used directly to lift heavy objects
	4.	cells rarely make use of

Which of the following most accurately describes a property of energy?
	1.	it rarely changes from one form to another
	2.	it easily changes from one form to another
	3.	it cannot change from one form to another
	4.	there is only one form of energy

Endergonic reactions always result in the
	1.	absorption of energy
	2.	release of energy
	3.	digestion of a food particle
	4.	destruction of poisons

Although most exergonic reactions occur spontaneously, some require an input of energy called the
	1.	input energy
	2.	initial energy
	3.	activation energy
	4.	commencing energy

The energy required to start an exergonic or endergonic reaction is usually
	1.	larger in an exergonic reaction
	2.	larger in an endergonic reaction
	3.	about the same in either type of the reaction
	4.	neither type of reaction requires energy to start
