Though there are exceptions such as Pepsin which works best at acidic p H 2.

The temperature also effects the enzyme activity- most enzymes are mesophiles which have optimum temperatures of 20-40*C.

The slope in the initial rate period is the initial rate of reaction v. Licensed under Copyrighted, but free for any purpose" data-lightbox="media-gallery-1567854912"From my studies I learn that there are factors which affect enzymes- these include p H, temperature, substrate concentration and enzyme concentration.

Most enzymes work best at a neutral p H of 7 or a slightly alkali p H of around 8-9.
