Cards

Term
Cellular Respiration
Definition
complex process in which cells make ATP by breaking down organic molecules
Term
Pyruvic Acid
Definition
three-carbon compound that is produced during glycolysis and needed for both aerobic and anaerobic pathways of cellular respiration that follows glycolysis
Term
NADH
Definition
reduced form of NAD+; and electron-carrying molecule that functions in cellular respiration
Term
Anaerobic
Definition
describes a process that does not require oxygen
Term
Aerobic Respiration
Definition
the process in which pyruvic acid is broken down and NADH is used to make a large amount of ATP; the part of respiration that is carried out by oxygen
Term
Glycolysis
Definition
the anaerobic breakdown of glucose to pyruvic acid, which makes a small amount of energy in the form of ATP
Term
NAD+
Definition
an organic molecule that serves as an electron carrier by being oxidized to NAD+ & reduced to NADH
Term
Fermentation
Definition
the breakdown of carbohydrates by enzymes, bacteria, yeast, or mold in the absence of oxygen
Term

 

Lactic Acid Fermentation

 

Definition

the chemical breakdown of carbohydrates that produces lactic acid as the main end product

Term

 

Alcohol Fermentation

 

Definition

the anaerobic process by which yeasts and other microorganisms break down sugars to form carbon dioxide and ethanol

Term
Kilocalorie
Definition
unit of energy equal to 1,000 calories
Term
Mitochondrial Matrix
Definition
the fluid that is inside the inner membrane of a mitochondrion
Term
Acetyl-CoA
Definition
acetyl coenzyme A, a compound that is synthesized by cells and that pays a major role in metabolism
Term
Krebs Cycle
Definition
a series of biochemical reactions that convert pyruvic acid into carbon dioxide and water; major pathway in animal, bacterial, and plant cells, and it releases energy
Term
Oxaloacetic Acid
Definition
chemical reaction in which a reactant loses one or more electrons such that the reactant becomes more positive in charge
Term
Citric Acid
Definition
six-carbon compound formed in the Krebs cycle
Term
FAD
Definition
flavin adenine dinucleotide, a compound that acts as a hydrogen acceptor in dehydration reactions
