What is the difference between the dorsal and ventral roots of the spinal nerves?

Explanation:

The group of nerve fibers from the dorsal and ventral root of spinal cord forms spinal nerve. The sensory neurons enters the grey matter of the spinal cord via dorsal root. The motor neurons moves out of the grey matter of the spinal cord via ventral root. The dorsal root originates directly from the spinal cord and moves towards dorsal root ganglion.

The ventral root consist of efferent fibers that carry information to maintain glandular and motor functions. The ventral horns of spinal cord consist of cell bodies of neurons involved in transfer of signal.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
