Saponification Select one: a. is a hydrolysis reaction. b. results in the production of triglycerides. c. is used to store energy for later use. d. is a reaction found in plant metabolism.

The correct option is A ( is a hydrolysis reaction).

Explanation:

Saponification is the alkaline hydrolysis ( using sodium hydroxide or potassium hydroxide) of fats and oil. It is commonly used for making of soaps which are used for washing and cleaning.

The process is a hydrolysis reaction because there is splitting of ester linkage bonds of triglycerides and addition of hydroxyl group from a hydroxide. This process leads to the production of alkaline salts of long chain fatty acids(soaps). This can be summarised below

Triglycerides (fats&oil) + base( NaOH)

> Soap + Alcohol

Tissue damage activates nociceptors or pain receptors in the skin. A signal is sent to the peripheral nerve to the spinal cord where neurotransmitters or chemical messengers are released. It activates other nerves to pass signal to the brain. The signals are relayed to the somatosensory cortex for sensation, frontal cortex for thinking and limbic system for emotional response.
