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

not only is it colder, it also becomes darker, less salty, and more dense.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
