Answer 2

Ester of fatty acids or compounds are called fats they are needed in the body for energy and work. Fats are essential for controlling blood pressure and cholesterol, absorbing nutrients and cell growth.

The two systems that are involved in fat synthesis are:

Option A. Digestive and circulatory

The systems can be explained as:

• The digestive system is the main system that is required for breaking food molecules and the fat consumed through food are also processed in the digestive tracts.

• The digested fats are transported in body organs through the circulatory system with the help of blood.

• The precursor of fatty acid synthesis NADPH and NADH needs H⁺ ions that are regulated by the circulatory system.

Thus, the digestive and circulatory systems are required in fat metabolism.
