1. A sensory receptor absorbs energy from some stimulus. The next step is (a) release of neurotransmitter (b) transmission of an action potential (c) energy transduction (d) transmission of a receptor potential (e) sensory adaptation

Introduction: Sensory receptors are found at the end of neurons. They are also specialized receptors that are in contact with neurons.
Answer to Problem 1TYU
Correct answer: After a sensory receptor absorbs energy from a stimulus, it is followed by energy transduction. Hence, the correct answer is option (c).
Explanation of Solution
Reason for the correct answer:
An external or internal stimulus induces the sensory receptors. In the process of stimulus reception, the receptors often absorb energy from the source of the stimulus. The type of energy absorbed varies and sensory receptors are highly sensitive to it. Once the energy is received, it is transduced as electrical signals to trigger action potential in the neurons for synaptic transmission.
Option (c) is given as “energy transduction”.
Energy transduction is the next step when a sensory receptor absorbs energy from a stimulus. Hence, the correct answer is option (c).
Reasons for incorrect answers:
Option (a) is given as, “release of neurotransmitter”.
Release of neurotransmitter occurs only after the energy that has been transduced induces an action potential in the neurons. Hence, option (a) is incorrect.
Option (b) is given as, “transmission of an action potential”.
Transmission of action potential occurs only after energy is transduced post absorption from the stimulus. Hence, option (b) is incorrect.
Option (d) is given as, “transmission of a receptor potential”.
Receptor potential has no role here. Hence, option (d) is incorrect.
Option (e) is given as, “sensory adaptation”.
Sensory adaptation is the final step, it does not occur after the sensory receptor absorbs stimulus. Hence, option (e) is incorrect.
Hence, the options (a), (b), (d), and (e) are incorrect.
Energy transduction is the next step when a sensory receptor absorbs energy from a stimulus.
