enzyme CORRECT ANSWER A biomolecule, either protein or RNA, that catalyzes a specific chemical reaction. It does not affect the equilibrium of the catalyzed reaction; it enhances the rate of the reaction by providing a reaction path with a lower activation energy. cofactor CORRECT ANSWER An inorganic ion or a coenzyme required for enzyme activity. coenzyme CORRECT ANSWER An organic cofactor required for the action of certain enzymes; often has a vitamin component. prosthetic group CORRE...

Micelles CORRECT ANSWER Spherical structures that contain anywhere from a few dozen to a few thousand amphipathic molecules. The non polar portions in the interior and the polar portions at the exterior surface, exposed to water Fluid Mosaic Model CORRECT ANSWER The concept that cell membranes are lipid bilayer structures that contain an assortment of polar lipids and proteins in a dynamic fluid arrangement Bilayer CORRECT ANSWER A second type of lipid aggregate in water, in which 2 lipid ...

Which of the following are characteristics of living systems? A. High degree of complexity and organization B. Extraction, transformation, and systematic use of energy to create and maintain structures and to do work C. Interactions of individual components are dynamic and coordinated D. A capacity for fairly precise self-replication while allowing enough change for evolution E. All of the above CORRECT ANSWER E. All of the above Which of the following structures are components of al...

amino acids CORRECT ANSWER α-Amino-substituted carboxylic acids, the building blocks of proteins. residue CORRECT ANSWER A single unit in a polymer; for example, an amino acid in a polypeptide chain. The term reflects the fact that sugars, nucleotides, and amino acids lose a few atoms (generally the elements of water) when incorporated in their respective polymers. R group CORRECT ANSWER (1) Formally, an abbreviation denoting any alkyl group. (2) Occasionally, used in a more general sense...
