Cards

Term
Cold Light
Definition
Light emmitting little or no heat.
Term
Energy
Definition
The ability to do work
Term
Kinetic Energy
Definition
Energy processed by a moving body
Term
Potential Energy
Definition
Energy stored in a body due to a body's position within an attractive or replusive force feild
Term
Entropy
Definition
The measure of the randomness or the disorder in a collection of bodies
Term
First Law of Thermodinamics
Definition
The total amount of energy in the universe is constant-no such thing as a free lunch
Term
Second Law of Themodinamics
Definition
The entropy of the universe increases with an change that occurs
Term
Metabolism
Definition
The sum total of all anabolic and catabolicprocesses in acell or organism-frequently energy is not readily available in a usuable form- usually energy must be converted to be useful
Term
Bond Energy
Definition
A measure of the stability of a chemical bond and represents the minimum enery required to break one mole of bonds between 2 particular atoms
Term
Exothermic(Exogonic) Reaction
Definition
Where the potential energy of the products is less than that of the reactants-there is a net release of energy
Term
Endothermic(Endogonic) Reaction
Definition
Where the potential energy of the products is greater than that of the reactants-there is a net absorbtion of energy
Term
Gibbs Free Energy
Definition
Energy available to do useful work
Term
What does THERMODINAMICS refer to?
Definition
The study of energy and energy transformations.
Term

How do organisms make ATP?

Definition

ATP is a byproduct of burning fuel used to drive the phosphates.

Term
What is CRISTAE and what is their function?
Definition
They are the inner folded membrane of mitochondria, and they increase surface area.
Term
What are two strategies different organisms use to obtain energy?
Definition
Photosynthesis and Cellular Resperation.
Term
What occurs during the process of Cellular Resperation?
Definition
Enzymes break bond in glucose, releasing the energy that is tored, which is then captured by ATP.
Term
Primary differences between photosynthesis and cellular resperation?
Definition
Cellular resperation is exothermiv-it releases energy, and photosynthesis is endothermic-it absorbs energy.
Term
How many kj/mol does glucose contain?
Definition
160
Term
Phosphorylation
Definition
The adition of an inorganic pgosphate to a molecule,
Term
[image]
Definition
Potential Energy Diagram
Term
Oxidizing Agent
Definition

 

A substance that tends to bring about oxidation by being reduced and gaining electrons.
Term
Reducing Agent
Definition
A substance that tends to bring about reduction by being oxidized and losing electrons.
Term
Oxidation
Definition
The combination of oxygen with a substance forming an oxide.
Term
Work
Definition
When a force moves a body through a distance.
Term
Reduction
Definition
Any process in whitch electrons are added to a atom or ion.
Term
Redox Reaction
Definition
chemical reaction involving both reduction and oxidation, which results in changes in oxidation numbersof atoms included in the reaction
Term
Anabolic Reaction
Definition
Build new molecules-require energy.
Term
Catbolic Reaction
Definition
Breakdown molecules-breakdown releses the energy used to fuel anabolic reactions.
