metabolism

Metabolism is the set of chemical reactions that happen in living organisms to maintain life. TERM 2

anabolism

DEFINITION 2 is the set of metabolic pathways that construct molecules from smaller units. TERM 3

catabolism

DEFINITION 3 is the set of pathways that break down molecules into smaller units and release energy. TERM 4

Aerobic respiration

DEFINITION 4 series of enzymatically catalyzed steps, similar to combustion, oxidative rxns to harvest energy TERM 5

glycolysis

DEFINITION 5 is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO + H+.

lactic acid pathway

when oxygen is not available NADH oxidized pyruvic acid accepts H+ yeilding lactic acid an anaerobic pathway TERM 7

glycogenesis

DEFINITION 7 Glycogenesis is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage. TERM 8

glycogenolysis

DEFINITION 8 Glycogenolysis (also known as "Glycogenlysis") is the conversion of glycogen polymers to glucose monomers. TERM 9

cori cycle

DEFINITION 9 The Cori cycle, named after its discoverers, Carl Cori and Gerty Cori, refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is converted back to lactate. TERM 10

krebs cycle

DEFINITION 10 The citric acid cycle - also known as the tricarboxylic acid cycle (TCA cycle), the Krebs cycle is a series of enzyme- catalysed chemical reactions, which is of central importance in all living cells that use oxygen as part of cellular respiration.

oxidative phosphorylation

production of ATP through coupling of electron transport system by phosphorylation of ADP TERM 12

chemiosmotic theory

DEFINITION 12 Chemiosmosis is the movement of ions across a selectively- permeable membrane, down their electrochemical gradient. TERM 13

lipogenesis

DEFINITION 13 Lipogenesis is the process by which acetyl-CoA is converted to fats. TERM 14

lipolysis

DEFINITION 14 lipase breaks down fat into FFAs(most significant energy carriers) and glycerol (diffuse out of cell to liver to make glucose) TERM 15

brown adipose tissue

DEFINITION 15 has ability to generate heat, richly vascularized and innervated

amino acid metabolism

Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids, and the breakdown of proteins (and other large molecules, too) by catabolism. TERM 17

oxidative deamination

DEFINITION 17 Oxidative deamination is a form of deamination that generates oxoacids in the liver.
