WebThe enzyme activities of each fraction were dependent on the presence of DTT. The optimum pH and the molecular weight of the enzyme in enzyme activity of ferulic acid … WebSep 19, 2024 · This is because most allosteric enzymes contain multiple sub-units which can affect each other when the substrate binds to the enzyme. Inhibition can affect either K 0.5, which is the substrate concentration for half-saturation, Vmax or both. This results in a shift of the curve to the right, and in the case of reducing Vmax, shifts the curve down.

WebHydrogen peroxide is toxic and must be converted to water and oxygen by the enzyme catalase. (5.5.1) 2 H 2 O → c a t a l a s e 2 H 2 O + O 2. Hydrogen peroxide is also commonly used as a household disinfectant. It bubbles when it is applied to cuts and scrapes because catalase is present in the fluids of the broken cells. WebDec 31, 2024 · Each enzyme has its own unique 3-D shape, which allows it to bind to substrates, the molecules required as inputs for a reaction. Enzymes have a structure …
