Potential energy includes: Positional, Gravitational, and Chemical.
True
Kinetic energy includes: Light, Electrical, and Thermal.
True
The ______ Law of Thermodynamics states that energy cannot be created or destroyed.
First
The ______ Law of Thermodynamics states that disorders will increase over time in a closed system.
Second
_______ convert inorganic molecules into energy-rich organic molecules.
Producers
______ organisms that obtain energy solely by breaking down organic molecules into inorganic molecules.
Consumers
Both consumers and producers essentially use cellular respiration.
True
_________ is the sum of energy use in all the chemical reaction in a organism.
Metabolism
Anabolic metabolism build molecules, taking energy invested to create polymers.
True
Catabolic metabolism break down molecules, releasing energy to disassemble polymers into monomers.
True
_______ chemical products have more energy than the reactants.
Endothermic
________ chemical products have less energy than the reactants.
Exothermic
Anabolic reactions tend to be endothermic.
True
Catabolic reactions tend to be exothermic.
True
Enzymes are not specific
False
Enzymes are unaltered in a reaction, reactions induce fit, which changes the shape of the enzyme and facilitate the reaction
True
Enzymes do not add energy to a reaction.
True
