Answer. The activity of enzymes is affected by the concentration of salt in their environments. Salts lower the freezing point of water, which in turn affects enzyme activity. In cold environments, this decrease in enzyme activity leads to an increase in the rate of chemical reactions. circle k burlington

"WebEnzyme activity is influenced by many different things including: substrates, products, presence of cofactors, and inhibitors. The effect of inhibitors is measured as a percentage called percent inhibition. During this experiment we observed the change in enzyme concentration, the change in substrate concentration " - How does concentration alter enzyme activity

How does concentration alter enzyme activity

WebThe enzyme does not lower the activation energy, what it does is provide an alternate route that is at a lower energy level, thus more molecules are able to react. Now those at a higher energy can still react via the route without the enzyme, but can also go the route of lower energy through use of the enzyme. WebApr 24, 2024 · A pH environment has a significant effect on an enzymes.
