Answer: True
Explanation:
Integrated pest management requires an expert knowledge of the pests, training and time. Some farmers may not have the resources to devote to this approach and may rely instead on the conventional spraying.
The integrated pest management is a great way which can be used to reduce the cost of the pesticides for a longer term and it also reduces the cost which will be required in future generations for pesticides.
It does not works every time as people do have that much patience and they switch to conventional spraying of pesticides on the crops.
Answer:
Substance A functions as an Allosteric inhibitor.
Explanation:
Allosteric inhibitor is a specific type of inhibitor that binds to the target enzyme at a specific site that is remote from the active site thus modulating or inhibiting the activity of that enzyme.
Allosteric interraction is of 2 types
1 Homotropic Interraction when substrate itself is a modulator,then the Interration that occurs between enzymes and target enzyme is known as Homotropic Interraction.
2 Hetarotropic Interraction During Hetarotropic interraction inhibitor bind to the specific site of the target enzyme that is different from the active site thereby inhibiting the activity of the target enzyme.
Here the product A binds to the enzyme that converts X to Y and decreasing the activity of that enzyme .This inhibition is a perfect example of Hetarotropic Allosteric Interraction
