Enymes can change shape when it denatures. An enzyme can denature if it's not at the pH or temperature that it's used to. A denatured enzyme can no longer function (an enzyme's funcion: to speed...
It is affected by those things. Precisely how ... well, if you knew the answer to that, you'd probably know how to solve the protein folding problem, and there would be big money and fame in that. In...
Enzymes are more active at a specific temperature. At higher temperatures they get denatured, so their structure breaks down. Same effect as pH. At lower temperatures they become inactive, in this...
In organic chemistry, chemicals have to have the right shapes so that they will fit together, in order to react in the way that is needed for whatever biological process which that chemical...
