Cards

Term
cellular respiration
Definition
a complex process in which cells make adenosine triphosphate (ATP) by breaking down organic compounds such as glucose
Term
pyruvic acid
Definition
three carbon compound that organic compounds such as glucose are converted into during glycolysis
Term
NADH
Definition
a high energy electron carrier molecule
Term
anaerobic
Definition
 a term to describe processes like glycolysis that do not require oxygen
Term
aerobic respiration
Definition
a process of breaking down pyruvic acid in the presence of oxygen using NADH to make ATP
Term
Glycolysis
Definition
an anaerobic process that breaks down glucose into pyruvic acid making ATP
Term
NAD+
Definition
this is a low energy molecule that accepts electrons to become NADH
Term
fermentation
Definition
process by which pyruvic acid is broken down in the abscence of oxygen (anaerobic conditions)
Term
lactic acid fermentation
Definition
pathway in which NAD+ is regenerated and lactic acid is given as a by product
Term
alcoholic fermentation
Definition
this is a pathway in which NAD+ is regenerated and ethyl alcohol is given off as a by product
Term
kilocalories
Definition
a unit of measure when dealing with energy, is equal to 1,000 calories
Term
mitochondrial matrix
Definition
the space in between the folds of the inner membrane of the mitochondria
Term
Acetyl CoA
Definition
the molecule that pyruvic acid is converted into before entering the Krebs Cycle
Term
Krebs Cycle
Definition
a biochemical pathway that breaks down acetyl CoA, producing CO2, hydrogen atoms, and ATP
Term
oxaloacetic acid
Definition
a four carbon compound that acetyl CoA combines with to start the Krebs Cycle
Term
citric acid
Definition
the six carbon compound formed when acetyl CoA combines with oxaloacetic acid during the Krebs Cycle
Term
FAD
Definition
this is a molecule similar to NAD+ that accepts electrons
