- Types of Enzyme Inhibition - BYJUS
A chemical binds to a location other than the active site in non-competitive inhibition (an allosteric site) When the inhibitor binds to the allosteric site, the enzyme’s active site undergoes a structural shift The active site and substrate no longer share affinity as a result of this alteration, preventing the substrate from binding
- If an enzyme solution is saturated with substrate, then the most . . .
Q Assertion :Competitive inhibitors compete with the natural substrate for their attachment on the active sites of enzymes Reason: In competitive inhibition, inhibitor binds to allosteric site of the enzyme Q The way enzyme helps a substrate to be attacked by reagent effectively is :
- Definition of Feedback Inhibition - BYJUS
Process of Feedback Inhibition Feedback inhibition is usually performed by an “allosteric site” on an enzyme, which alters the shape of enzyme and, as a result, the behaviour of the active site The end product binding to the allosteric site delays or prevents the enzyme’s activity, resulting in slight or no further end product being produced The enzyme will encounter rarer particles of
- In feedback inhibition mechanism to control the rate of a metabolic . . .
The correct option is option (C): Explanation of the correct option: Feedback inhibition is a type of allosteric regulation In feedback inhibition, the enzymes regulate the reaction and the end product act as the inhibitor of this enzyme Excess end product of the reaction enters and binds to the allosteric site of the initiator enzyme
- Assertion: Allosteric enzymes show feedback inhibition.
Q Explain the rote of allosteric site in enzyme inhibition? Q Assertion :Competitive inhibitors compete with the natural substrate for their attachment on the active sites of enzymes Reason: In competitive inhibition, inhibitor binds to allosteric site of the enzyme
- Why does the inhibitor compete with the substrate in enzymes?
The geometry of the active site is altered by the binding of the inhibitor at the allosteric site, rendering the substrate unable to recognize it As a result, it competes with the natural substrate for attachment to enzyme active sites during competitive inhibition and does not bind to allosteric sites

The enzyme phosphofructokinase-1 (PFK-1) catalyses the transference of a phosphoryl group from ATP to fructose-6-phosphate (F6P), resulting in ADP and fructose-1,6-bisphosphate (FBP) One of the most significant enzymes that regulates glycolysis is phosphofructokinase-1 (PFK-1) It is a four subunit allosteric enzyme regulated by several activators and inhibitors Fructose 6-phosphate and ATP
- Which of the following statements is not true about enzyme inhibitors?
(a) Inhibit the catalytic activity of the enzyme (b) Prevent the binding of substrate (c) Generally a strong covalent bond is formed between an inhibitor and an enzyme (d) Inhibitors can be competitive or non-competitive Solution Answer: (c) Inhibitors are chemical substances which tend to reduce the activity of a particular enzyme
