Metabolic Processes Flashcards
ATP
Adenosine Triphosphate
Primary energy carrier in cells
ADP
Adenine Diohosphate
Molecule that ATP becomes after losing a phosphate group
Phosphorylation
Process of adding a phosphate group to a molecule i.e. ADP to form ATP
Exergonic Reaction
Reaction that releases enery
Exergonic Reaction
Reaction that releases energy
Endergonic Reaction
Reaction that absorbs energy
Metabolism
Sum of all chemical reactions in an organism
Anabolism
Building of complex molecules from simpler ones, requiring energy
Catabolism
Breakdown of complex molecules into simpler ones, releasing energy
Cellular Respiration
Process by which cells break down glucose to produce ATP
Glycolysis
First step un cellular respiration, occurring in the cytoplasm, where glucose is split into 2 pyruvate molecules
Pyruvate Oxidation
Conversion of pyruvate into Acetyl-CoA before entering the Krebs cycle
Krebs Cycle (Citric Acid Cycle)
Series of chemical reactions in mitochondria that generate ATP and electron carriers
Electron Transport Chain
Chain of proteins in inner mitochondrial membrane that uses electrons to generate ATP
Oxidative Phosphorylation
Process of ATP production using ETC and ATP synthase
ATP Synthase
Enzyme that synthesizes ATP using a proton gradient
NAD+
Nicotinamide Adenine Dinucleotide
Electron carrier that becomes NADH when reduced
FAD
Flavin Adenine Dinucleotide
Electron carrier that becomes FADH2 when reduced
Chemiosmosis
Movement of hydrogen ions across membrane to drive ATP production
Anaerobic Respiration
Type of respiration that doesn’t require oxygen
Lactic Acid Fermentation
Process where pyruvate is converted into lactic acid in muscle cells
Alcoholic Fermentation
Process where pyruvate is converted into ethanol & carbon dioxide in yeast
Enzyme
Protein that speeds up chemical reactions in cells
Substrate
Reactant that an enzyme acts upon
