BIO 1001 EXAM 3 QUESTIONS AND 100%
VERIFIED CORRECT ANSWERS!!
Energy that is contained in molecules and released by chemical reactions
Chemical reactions
Stored energy; (i.e. chemical energy in bonds, electrical charge in a battery, rock at top of
hill)
Potential energy
The energy of movement; (i.e. light, heat, electricity, and the movement of
objects)
Kinetic energy
What is the first law of thermodynamics?
Energy can't be created or destroyed, but can change form
The Law of Conservation of Energy (first law of thermodynamics) states that total amount
of energy within a ____________ system remains constant unless energy is added or
removed.
closed
What is the second law of thermodynamics?
The amount of useful energy decreases when energy is converted from one form to another.
A measure of disorder
, Entropy
The burning of glucose is an example of what kind of reaction?
Exergonic
This type of reaction releases energy
Exergonic
This type of reaction requires a net input of energy
Endergonic
All chemical reactions require _____________ __________ to get started.
Activation energy
In an exergonic reaction, the negatively charged electron shells of atoms repel one another
and __________ bond formation.
inhibit
Molecules need to be _________ ______ to overcome electronic repulsion and react.
moving fast
