Enzymes are highly specific proteins that function best at certain pHs. A change in pH would affect its structure; too high or too low would cause denaturation. When this happens, the enzyme won’t have the correct structure to function as a catalyst. Therefore, reaction rate will slow.
Hope this helps!!
Gluconeogenesis is a
metabolic pathway that results in the generation of glucose from non-carbohydrate
molecules, from breakdown of amino acids or fatty acids and from other steps in
metabolism that include pyruvate and lactate. This pathway is one of several
main mechanisms used by humans and many other animals to maintain blood glucose levels<span>, avoiding low
levels of blood glucose.</span>
The answer is Interspecific competition.
