841116069active siteThe part of an enzyme molecule where a substrate molecule attaches (by means of weak chemical bonds); typically, a pocket or groove on the enzyme's surface.0
841116070active transportThe movement of a substance across a biological membrane against its concentration gradient, aided by specific transport proteins and requiring input of energy (often as ATP).1
841116071adenosine triphosphate (ATP)Main energy source for cells.2
841116073aquaporinA transport protein in the plasma membrane of some plant or animal cells that facilitates the diffusion of water across the membrane (osmosis).3
841116074cellular respirationThe aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, and oxidative phosphorylation (the electron transport chain and chemiosmosis).4
841116076chemical energyEnergy available in molecules for release in a chemical reaction; a form of potential energy.5
841116077coenzymeAn organic molecule serving as a cofactor. Most vitamins function as coenzymes in important metabolic reactions.6
841116079cofactorA nonprotein molecule or ion that is required for the proper functioning of an enzyme. See also coenzyme.7
841116080competitive inhibitorA substance that reduces the activity of an enzyme by binding to the enzyme's active site in place of the substrate. A competitive inhibitor's structure mimics that of the enzyme's substrate.8
841116081concentration gradientAn increase or decrease in the density of a chemical substance in an area. Cells often maintain concentration gradients of ions across their membranes. When a gradient exists, substances tend to move from where they are more concentrated to where they are less concentrated.9
841116083diffusionThe spontaneous tendency of a substance to move down its concentration gradient from where it is more concentrated to where it is less concentrated.10
841116084endergonic reactionAn energy-requiring chemical reaction, which yields products with more potential energy than the reactants. The amount of energy stored in the products equals the difference between the potential energy in the reactants and that in the products.11
841116085endocytosisCellular uptake of molecules or particles via formation of new vesicles from the plasma membrane.12
841116087energyThe capacity to perform work, or to rearrange matter.13
841116088energy couplingIn cellular metabolism, the use of energy released from an exergonic reaction to drive an endergonic reaction.14
841116090entropyA measure of disorder. One form of disorder is heat, which is random molecular motion.15
841116092enzymeA protein (or RNA molecule) that serves as a biological catalyst, changing the rate of a chemical reaction without itself being changed into a different molecule in the process.16
841116094exergonic reactionAn energy-releasing chemical reaction in which the reactants contain more potential energy than the products. The reaction releases an amount of energy equal to the difference in potential energy between the reactants and the products.17
841116096exocytosisThe movement of materials out of the cytoplasm of a cell by the fusion of vesicles with the plasma membrane.18
841116098facilitated diffusionThe passage of a substance through a specific transport protein across a biological membrane down its concentration gradient.19
841116099feedback inhibitionA method of metabolic control in which a product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.20
841116101first law of thermodynamicsThe principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed.21
841116102fluid mosaicA description of membrane structure, depicting a cellular membrane as a mosaic of diverse protein molecules embedded in a fluid bilayer made of phospholipid molecules.22
841116104heatThermal energy; the amount of energy associated with the movement of the atoms and molecules in a body of matter. Heat is energy in its most random form.23
841116106hypertonic solutionReferring to a solution that, when surrounding a cell, will cause the cell to lose water.24
841116107hypotonic solutionReferring to a solution that, when surrounding a cell, will cause the cell to take up water.25
841116109induced fitThe change in shape of the active site of an enzyme, induced by entry of the substrate so that it binds more snugly to the substrate.26
841116110isotonic solutionA solution having the same solute concentration as another solution, thus having no effect on passage of water in or out of the cell.27
841116111kinetic energyThe energy of motion; the energy of a mass of matter that is moving. Moving matter does work by imparting motion to other matter.28
841116112metabolismThe totality of an organism's chemical reactions.29
841116113noncompetitive inhibitorA substance that impedes the activity of an enzyme without entering an active site. By binding elsewhere on the enzyme, a noncompetitive inhibitor changes the shape of the enzyme so that the active site no longer functions.30
841116115osmoregulationMethod by which organisms regulate solute concentrations and balance the gain and loss of water.31
841116116osmosisThe diffusion of water across a selectively permeable membrane.32
841116117passive transportThe diffusion of a substance across a biological membrane, without any input of energy.33
841116118phagocytosisCellular "eating"; a type of endocytosis whereby a cell engulfs macromolecules, other cells, or particles into its cytoplasm.34
841116120phosphorylationThe transfer of a phosphate group, usually from ATP, to a molecule. Nearly all cellular work depends on ATP energizing other molecules by phosphorylation.35
841116122pinocytosisCellular "drinking"; a type of endocytosis in which the cell takes fluid and dissolved solutes into small membranous vesicles.36
841116123potential energyThe energy that matter possesses because of its location or arrangement. Water behind a dam and chemical bonds possess potential energy.37
841116124receptor-mediated endocytosisThe movement of specific molecules into a cell by the inward budding of membranous vesicles. The vesicles contain proteins with receptor sites specific to the molecules being taken in.38
841116126second law of thermodynamicsThe principle whereby every energy conversion reduces the order of the universe, increasing its entropy. Ordered forms of energy are at least partly converted to heat.39
841116128selective permeabilityA property of biological membranes that allows some substances to cross more easily than others and blocks the passage of other substances altogether.40
841116129substrate(1) A specific substance (reactant) on which an enzyme acts. Each enzyme recognizes only the specific substrate or substrates of the reaction it catalyzes. (2) A surface in or on which an organism lives.41
841116130thermodynamicsThe study of energy transformation that occurs in a collection of matter. See first law of thermodynamics; second law of thermodynamics.42
841116132tonicityThe ability of a solution surrounding a cell to cause that cell to gain or lose water.43
