Question

atp allosterically inhibits enzymes in atp - producing pathways. the result of this is called ____________. competitive inhibition feedback inhibition cooperativity positive feedback denaturing i dont know yet

Explanation:

• Competitive inhibition: Occurs when a molecule competes with the substrate for the active site of an enzyme. This is not the case here as ATP is acting at an allosteric site (not the active site).
• Feedback inhibition: In a metabolic pathway, when the end - product (in this case, ATP) allosterically inhibits an enzyme (usually an early - acting enzyme) in the pathway that produces it. This is exactly what is described in the question.
• Cooperativity: Refers to a phenomenon where the binding of a substrate to one subunit of a multi - subunit enzyme affects the binding of substrates to other subunits. It is not related to end - product inhibition.
• Positive feedback: In positive feedback, the end - product enhances the pathway. But here, ATP is inhibiting the pathway, so it is not positive feedback.
• Denaturing: Denaturing is the process of an enzyme (or protein) losing its native structure (usually due to factors like heat, pH changes). This is not relevant to the described regulatory mechanism.

Answer:

feedback inhibition
