Which of the following is a characteristic of neurons?
A
They are capable of generating and transmitting electrical impulses.
B
They undergo frequent cell division in adult mammals.
C
They store large amounts of glycogen for energy.
D
They primarily function in producing antibodies.
Verified step by step guidance1
Step 1: Begin by identifying the primary function of neurons. Neurons are specialized cells in the nervous system responsible for communication. Their main role is to generate and transmit electrical impulses, which allow for rapid signaling across the body.
Step 2: Evaluate the statement about frequent cell division. Neurons in adult mammals typically do not undergo frequent cell division. Most neurons are post-mitotic, meaning they do not divide after differentiation.
Step 3: Consider the statement about glycogen storage. Neurons do not store large amounts of glycogen for energy. Instead, they rely on a constant supply of glucose from the bloodstream for their energy needs.
Step 4: Analyze the statement about antibody production. Neurons do not produce antibodies. Antibodies are produced by specialized immune cells called B lymphocytes, not neurons.
Step 5: Conclude that the correct characteristic of neurons is their ability to generate and transmit electrical impulses, as this is their defining feature in the nervous system.
