Cards

Term
cellular respiration
Definition
how cells make ATP
Term
pyruvic acid
Definition
3-carbon compounds produced by glycolysis and needed for posterior steps
Term
NADH
Definition
reduced form of NAD+, electron-carrying molecule in cellular respiration
Term
anaerobic respiration
Definition
process doesn't need O
Term
aerobic respiration
Definition
pyruvic acid is broken down and NADH used to make lots of ATP (needs O)
Term
glycolysis
Definition
anaerobic breakdown of glucose to pyruvic acid, makes little ATP
Term
NAD+ (nicotinamide adenine denucleotide)
Definition
organic molecules carry electrons by being oxidized to NAD+ and reduced to NADH
Term
fermentation
Definition
anaerobic breakdown of carbs by enzymes, bacteria, yeast, or molds
Term
lactic acid fermentation
Definition
chemical breakdown of carbs that make up lactic acid
Term
alcoholic fermentation
Definition
anaerobic process of yeast and microorganisms breakdown sugars to CO2 and ethanol
Term
kilocalorie
Definition
1000 calories
Term
mitochondrial matrix
Definition
fluid in inner membrane of mitochondria
Term
acetyl-CoA (acetyl coenzyme A)
Definition
compound make by cells and helps in metabolism
Term
Krebs cycle
Definition
biochemical reactions that change pyruvic acid into CO2 and H2O in many organisms that releases, popular form of oxidation
Term
oxaloacetic acid
Definition
4-carbon compound of Krebs cycle that combines with acetyl-CoA to form citric acid
Term
citric acid
Definition
6-carbon compound made in Krebs cycle
Term
FAD (flavin adenine denucleotide)
Definition
compound acts as a hydrogen acceptor in dehydrogenation reactions
