Term
Kilocalories
Definition
The quantity of heat required to raise the temperature of 1 kilogram of water by 1 degrees Celsius.
Term
Redox Reaction
Definition
The movement of electrons from one molecule to another is an oxidation-reduction reaction.
Term
Oxidation
Definition
In a redox reaction, the loss of electrons from one substance.
Term
Reduction
Definition
The addition of electrons to another substance.
Term
Dehydrogenase
Definition
A key player in the process of oxidizing glucose.
Term
NAD+
Definition
Another key player in the process of oxidizing glucose, a coenzyme. 
Term
Electron transport Chain
Definition
Electron carrier molecules are uilt into the inner membrane of a motochondrian. 
Term
Glycolysis
Definition
Occurs in the cytoplasmic fluid of the cekk, that is, outside the organelles. First part of Cellular Respiration. 
Term
Citric Acid Cycle
Definition
The second stage of Cellular Respration. Completes breakdown of glucose be decomposing a derivative of pryvate to carbon dioxide. 
Term
Oxidative Phosphorylation
Definition
The thrid and final step of Cellular Respiration. involves the electron transport chaing and a process known as chemoismosis. (ATP). [image]
Term
Chemiosmosis
Definition
The potential energy of this concentration gradient is used to make ATP.
Term
ATP synthases
Definition
Protein complexes built into the inner membrane that synthesize ATP.
Term
Substrate-level phosphorylation
Definition
an enzyme transfers a phosphate group from a substrate molecule directly to ADP, forming ATP.
Term
Intermediates
Definition
The compounds that form btween te initial reactant, glucose, and the final product, pyruvate, are known as intermediates. 
Term
Acetyl CoA
Definition
Is a high-energy fuel molecule  for the citric acid cycle.
Term
Lactic Acid Fermentation
Definition
This oxidizes NADH to NAD+ and produces lactate.
Term
Alcohol Fermentation
Definition
This oxidizes NADH to NAD+ and produces ethanol and CO2.
Term
Obligate anaerobes
Definition
Prokaryotes that live in stagnant ponds and deep in soil. require anaerobic conditions and are poisoned by oxygen. 
Term
Facultative Anaerobe
Definition
Can make ATP either by fermentationor by oxidative phosphorylation, depending on whether O2 is available.
