WebThe enzyme-substrate complex can also lower activation energy by bending substrate molecules in a way that facilitates bond-breaking, helping to reach the transition state. Finally, some enzymes lower activation energies by taking part in the chemical reaction themselves. That is, active site residues may form temporary covalent bonds with ... WebNov 7, 1986 · These effects will be superimposed upon a progressive loss of catalytic activity if the enzyme is unstable, either spontaneously or as a result of an added reagent. … WebThe effect of enzymes is strongly dependent on the pH value (see p.30). When the activity is plotted against pH, a bell-shaped curve is usually obtained (1). With animal enzymes, the pH optimum—i.e., the pH value at which enzyme activity is at its maximum—is often close to the pH value of the cells (i.e., pH 7). [Pg.94] girl \u0026 the goat chicago menu
