Enzyme Biochemistry Quiz

Enzyme Kinetics = Study of the rates at which enzymes catalyze chemical reactions Enzyme Mechanism = Investigation of the specific steps involved in enzyme-catalyzed reactions Regulation of Enzyme activity = Control of enzyme function to maintain homeostasis in the body Biological catalysis = The process of accelerating chemical reactions within living organisms

Late 1700s studies on digestion of meat = First recognition and description of biological catalysis 1800s examinations of starch to sugar conversion = Early investigations into biological catalysis using plant extracts 1850s discovery of fermentation by yeast = Louis Pasteur's conclusion about the role of 'ferments' in sugar fermentation 1897 discovery of yeast extracts fermentation = Eduard Buchner's proof that fermentation is promoted by molecules outside of cells

Enzyme Alteration of Reaction Rate = Enzymes catalyze reactions without being consumed in the process Enzyme Composition = Most enzymes are protein in nature with large molecular weight Enzyme Mediation of Body Reactions = Virtually all reactions in the body are mediated by enzymes Enzyme Exceptions = Some enzymes are RNA-based, known as ribozymes

<p>Enzyme Definition = Protein catalysts that alter the rate of reactions without being changed in the overall process Ribozymes = RNA-based enzymes that are exceptions to the protein nature of most enzymes Enzyme Function = Directing all metabolic events in the body Enzyme Weight = Most enzymes are protein in nature and have a large molecular weight</p> Signup and view all the answers
