|
Anabolism
|
reactions in which small molecules are put together to build larger ones. Anabolic reactions require energy.
|
|
|
Catabolism
|
reactions in which large molecules are broken down to smaller ones. Catabolic reactions usually release energy.
|
|
|
Electron Transport/Oxidative Phosphorylation
|
energy is released at each stage of electron carriers (net ATP through glycolysis, Krebs, electron transport = 36-38 per 1 molecule glucose); main end-products are carbon dioxide and water.
|
|
|
Fatty Acid Oxidation
|
the metabolic breakdown of fatty acids to acetyl CoA.
|
|
|
Gluconeogenesis
|
the making of glucose from a noncarbohydrate source.
|
|
|
Glycogenolysis
|
breakdown of glycogen into glucose; requires glucose-6-phosphate for conversion.
|
|
|
Glycolysis
|
the metabolic breakdown of glucose to pyruvate. Glycolysis does not require oxygen.
|
|
|
Krebs Cycle
|
aka: oxidative decarboxylation, TCA cycle, citric acid cycle) – occurs in mitochondria of cells, carbon dioxide and hydrogen are given off;
|
|
|
Metabolism
|
sum/total of all chemical reactions taking place in cells
|
|
|
Urea Cycle
|
urea synthesized via deamination of amino acids; amino acids stripped of nitrogen (amino group) enter Krebs cycle.
