Which pathway type is responsible for regulating the activity rather than the synthesis of enzymes?
Understand the Problem
The question is asking to identify the type of pathway that regulates the activity of enzymes as opposed to their synthesis. It provides four options to choose from.
Answer
Allosteric regulation.
The pathway type responsible for regulating the activity of enzymes rather than their synthesis is allosteric regulation.
Answer for screen readers
The pathway type responsible for regulating the activity of enzymes rather than their synthesis is allosteric regulation.
More Information
Allosteric regulation involves the binding of regulator molecules to an enzyme at sites other than the active site, causing conformational changes that alter enzyme activity. This mechanism is often used in feedback inhibition, where the end product of a metabolic pathway inhibits an upstream process.
Tips
One common mistake is confusing enzyme regulation with enzyme synthesis. It's important to note that allosteric regulation modifies enzyme activity rather than increasing or decreasing the quantity of the enzyme itself.
