Final answer:
The metabolic center of a neuron, also known as the soma, contains the nucleus and mitochondria. The axon transmits the electrical signal to the target cell.
Step-by-step explanation:
The metabolic center of a neuron, also known as the soma, is responsible for various functions including the synthesis of proteins and energy production. The soma contains the nucleus, which houses the genetic material of the neuron, and mitochondria that generate energy. While the dendrites receive signals from other neurons, it is the axon that carries the electrical signal, known as the action potential, to the target cell.
