Water: high permeability through lipid bilayers 3. ATP-dependent proton pump: mechanism by which the stomach maintains its pH of 1-2 4. Acetyl CoA: converted from pyruvate in the presence of oxygen 5. R2C2: inactive form of PKA 6. Acetylsalicylic acid (aspirin): substance that inhibits prostaglandin H2 synthase-1 by blocking the channel through which the substrate, arachidonate, travels 7. Lectins: proteins that bind to specific carbohydrate structures 8. Spingosine: complex amino alcohol backbone for membrane lipids 9. Phospholipid: lipid with two acyl chains, a glycerol backbone, and a polar head group 10.Zymogen activation: mechanism of permanently activating a protease by covalent modification 11.Lipid raft: complex between cholesterol and membrane phospholipids 12.Biotin: essential nutrient that is required for the carboxylation of pyruvate in humans 13.Closed biomolecular sheets: formed spontaneously by lipid bilayers 14.Amphibolic: pathways that can be anabolic or catabolic depending on the energy conditions of the cell 15.Phosphoenolpyruvate carboxykinase: reaction that uses GTP and not ATP as its high-phosphoryl-transfer potential donor 16.Lateral diffusion: process by which lipids and proteins move in the membrane layer 17.Coenzyme A: activated carrier of acyl groups 18.Niacin: NADH (electron carrier) is derived from this vitamin 19.Mitochondria: location in cell for the citric acid cycle 20.UDP-glucose: intermediate necessary for the conversion of galactose to glucose 21.cAMP: molecule that functions as a secondary messenger 22.Glycogen: storage form of glucose of animals 23.Glucose: principle carbohydrate in living systems 24.Asparagine: residue attached to the carbohydrate portion of N-linked glycoproteins 25.Amylopectin: branched polymer of glucose 26.Triacylglycerol: Storage form of fatty acids 27.Vitamins: small organic molecules, required in the diet of higher organisms, components of coenzymes 28.Enantiomers: stereoisomers that are mirror images of each other 29.Digestion: first stage in the oxidation of foods 30.Liver: major tissue in which gluconeogenesis takes place 31.Protein Kinase C (PKC): enzyme that becomes active when bound to Ca2+ and diacylglycerol 32.ATP: “chemical currency” of metabolism 33.Pyruvate: product of aerobic glycolysis 34.Phosphorylation: type of enzyme regulation process that inhibits the PDH complex 35.Pyruvate dehydrogenase: large, multi-subunit enzyme complex that links glycolysis and the citric acid cycle under aerobic conditions 36.Phototrophs: organisms that use energy from sunlight and convert it to chemical energy 37.Galactokinase: enzyme responsible for converting galactose to be used in the glycolytic pathway 38.Oxaloacetate: intermediate that is decarboxylated and phosphorylated to produce phosphoenolpyruvate 39.Gluconeogenesis: process by which noncarbohydrate precursor molecules are converted into glucose 40.Amphipathic: Molecules that have both hydrophilic and hydrophobic moieties 41.Carbohydrates: found in the gut, first digested by α amylase 42.Pepsin: protease released by the stomach for the digestion of protein 43.Small G Proteins: family of proteins, includes Ras 44.Obligate anaerobles: organism that cannot survive in the presence of oxygen 45.Protein Kinase A (PKA): enzyme that becomes active when bound to cAMP au.
