WebThe Vmax equals the product of the concentration of active enzyme sites times the turnover rate, kcat. This is the number of substrate molecules each enzyme site can convert to product per unit time. If you know the concentration of enzyme, you can fit the curve to determine kcat and Km. The curve will be identical to the Michaelis-Menten fit. WebLab # 11: Enzyme Activity I. Abstract Enzymes are multi-structured proteins that behave and function as biological catalysts.

WebTo catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. WebName: Bio 100 - Lab 4 a) Predict and draw on the graph below what the % enzyme activity curve would look like for a homeothermic and a poikilothermic animal if their body temperature were to change. Be sure to label each curve as homeothermic or … WebEnzymes are catalysts that reduce the needed activation energy so these reactions proceed at rates that are useful to the cell. The study of enzyme kinetics can help us understand the function and regulation of enzymes. Enzyme progress curves.
