Ph Enzyme Change Active Site Substrate Affect Activity

Altering pH levels affects enzyme activity by changing the charges on amino acids within the active site and disrupting bonds, which can change the active site's shape and inhibit substrate binding.

Changes in pH alter the charges on amino acids in the enzyme's active site and can disrupt hydrogen and ionic bonds, changing the active site's shape and preventing substrate binding.

Front How does pH affect enzyme activity?
Back A change in pH alters the charges on the amino acids that make up the active site of the enzyme. therefore the substrate can no longer become attached to the active site and so the enzyme substrate complex cannot be formed.

the change in pH alter the hydrogen and ionic bonds in the enzymes structure.
