What are three important organelle in cells?

Three important organelles in the cell are nucleus, mitochondria and rough endoplasmic reticulum.

Explanation:

Cellular organelles are structures that are mainly found in all eukaryotic cells and are linked to the fulfilment of their main functions.  In a cell all organelles are important and each one of them fulfills a specific function. Three of the main organelles of the cell are :

Cell nucleus: structure that is located in the center of the intracellular space and contains all the genetic information, in the form of DNA. Mitochondria: responsible for hosting all metabolic processes that lead to energy production, such as oxidative phosphorylation. Rough endoplasmic reticulum: it is associated to another important organelle, the ribosome, being in charge of the synthesis, transport and secretion of proteins.

Prokaryotic cells, whose structure is simpler, lack nuclei and most organelles.

Fats are digested through conversion into free fatty acids, which are stored in a form known as triglycerides in the adipose tissue. ... In the mitochondria, the fatty acids are oxidized in the process that creates adenosine triphosphate (ATP), the energy-producing fuel.
