|
pH affects the enzymes shape by?
|
|
Changing the charges on the R groups, preventing bonds from forming in the same places
|
|
|
Breaking bonds within the protein structure, changing its shape
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Explanation. At very acidic and alkaline pH values the shape of the enzyme is altered so that it is no longer complementary to its specific substrate. This effect can be permanent and irreversible and is called denaturation.
Detailed explanation-2: -The change of pH will lead to the ionization of amino acids atoms and molecules, change the shape and structure of proteins, thus damaging the function of proteins. Enzymes are also proteins, which are also affected by changes in pH.
