Answer: The myelinated nerve fibres are enveloped with Schwann cells, it form a myelin sheath around the axon.
Unmyelinated nerve fibres is enveloped by a Schwann cell that doesn't form a myelin sheath around the axon, and found in autonomous and the somatic neural systems. Sympathetic Nervous system is part of Autonomous Nervous system.
Explanation:
I'm Smart
Energy is released from ATP by the breaking of the phosphate bond. A<span>denosine triphosphate, or ATP, consists of a sugar called ribose, the molecule adenine and three phosphate groups. During the hydrolysis of ATP, the last phosphate group is transferred to another molecule, thus breaking the phosphate bond. This reaction causes energy to be released to power other activities within the cell.</span>
photosynthesis: needs light to happen
Cellular respiration: waste products are carbon dioxide and water.
