The essay on responses of enzyme activity from ph and concentration other 3 test tubes discussion the data from exercise a provided evidence to support the hypothesis that ph affects enzyme activity.

The rate of this reaction is affected by inhibitory compounds, enzyme and substrate concentration, ph and temperature being that the subject reaction takes place in humans (as well as other living things), it is hypothesized that the reaction contained therein, take place at or near optimal conditions. During the enzyme reaction product accumulates in amounts exceeding by far the intrinsic enzyme concentration however, the conclusion from the product formed back to the amount of enzyme in the sample comprises various difficulties and pitfalls enzymes differ in their ph optima and not every enzyme has its ph optimum activity just at the. Often enzymes operate at a maximum activity when the ph is close to the pk a of the enzyme's active site inhibition : inhibitors can decrease reaction rates via binding to the enzyme in the active site, or binding to a region of the enzyme that inactivates the substrate binding site. For example, if we take an enzyme with an optimal ph (ph opt) of 70 and place it in an environment at ph 60 or 80, the charge properties of the enzyme and the substrate may be suboptimal, such that binding and hence the reaction rate are lowered if we then readjust the ph to 70, the optimal charge properties and hence the maximal activity.

The effect of ph and enzyme concentration on enzyme activity abstract enzymes help many chemical reactions to occur in living organisms enzymes are very specific molecules, each enzyme has a certain type of active site necessary for the reaction to happen.
