Match the term or concept with the best definition or description available A. Scaffold protein A protein that serves both to link together a set of interacting proteins and to position them at a specific location in a cell . Coenzyme Kinase Allosteric protein Feedback inhibition Active site Type of metabolic regulation in which the activity of an enzyme acting near the beginning of a reaction pathway is D inhibited by a product of the pathway Region of an enzyme surface to which a substrate molecule binds in order to undergo a catalyzed reaction A protein (mostly) catalyst that speeds up a reaction, oftenEzyme by a factor of a million or more, without itself bein changed or consumed in the reaction Transition state YEnzyme that transfers the terminal phosphate group of ATP to a specific amino acid in a target protein YRate-limiting structure that forms transiently in the course of a chemical reaction and has the highest free energy of any reaction intermediate Protein that changes its conformation (and often its activity) when it binds a regulatory molecule or when it is covalently modified Small molecule that is tightly associated with a protein catalyst, frequently positioned at the active site where it directly participates in the chemical reactionExplanation / Answer
A protein that serves both to link together a set of interacting proteins and to position them at a specific location in a cell: A. Scaffold protein
Type of metabolic regulation in which the acitvity of an enzyme acting near the beginning of a reaction pathway is inhibited by a product of the pathway: E. Feedback inhibition
Region of an enzyme surface to which a substrate molecule binds in order to undergo a catalyzed reaction: F. Active site
A protein (mostly) catalyst that speeds up a reaction, often by a factor of a million or more, without itself being changed or consumed in the reaction: G. Enzyme
Enzyme the transfers the terminal phosphate group of ATP to a specific amino acid in a target protein: C. Kinase
Rate limiting strcuture that forms transiently in the course of a chemical reaction and has the highest free energy of any reaction intermediate: H. Transition state
Protein that changes it's conformation when it binds a regulatory molecule or when it is covalently modified: D. Allosteric protein
Small molecule that is tightly associated with a protein catalyst, frequent associated at the active site where it directly participates in the chemical reaction: B. Coenzyme
