What would happen to enzymes if blood pH moved too far away from its optimal levels?
A
Enzymes would remain unaffected and continue to function normally.

D
Enzymes would change their substrate specificity.
Verified step by step guidance1
Understand that enzymes are proteins that catalyze biochemical reactions and are sensitive to changes in their environment, including pH levels.
Recognize that each enzyme has an optimal pH range where it functions most efficiently. For human blood, the optimal pH is around 7.4.
Learn that if the pH deviates significantly from the optimal range, the enzyme's structure can be altered. This process is known as denaturation.
Denaturation involves the unfolding of the enzyme's three-dimensional structure, which is crucial for its ability to bind to substrates and catalyze reactions.
Realize that once denatured, enzymes lose their functionality and cannot perform their catalytic role effectively, impacting metabolic processes.
