Answer;

A. A-delta fibers

A-delta fibers transmit pain that is sharp, nonchronic, and well localized.

Explanation;

-The information about touch and pain is transmitted to the spinal cord and brain by primary afferent axons - these are the nerve fibers connected to the different types of receptors in the skin, muscle and internal organs.

-The different nerve fiber groups are; A-alpha, A-beta, A-delta and C-nerve fibers.A-alpha, A-beta and A-delta nerve fibers are insulated with myelin. C-nerve fibers are unmyelinated.

-A-delta nerve fibers carry information related to pain and temperature. A-delta nerve fibers can conduct action potentials as fast as a sprinter in the Olympics.

How do ETS reactions produce ATP?
Norma-Jean [14]

ATP synthesization -  Simple and complex lipids or carbohydrates are used to produce ATP through redox reactions. After the hydrolysis of complex carbohydrates, glucose and fructose are formed and the triglycerides are metabolized to form glycerol and fatty acids. ATP is then synthesized by oxidative phosphorylation and photophosphorylation during the energy production with in the living organisms. ATP production usually takes place in the mitochondria of the cell.  The important pathways by which ATP is generated are glycolysis, the citric acid cycle (or the Kreb’s cycle), and the electron transport chain (or the oxidative phosphorylation pathway).  In these three cycles of  cellular respiration  adenosine diphosphate (ADP) is converted  to ATP and energy is released  from molecules.
