WHAT FUNTION OF THE MITOCHOMDRIA IS TO 1) PRODUCE PROTEINS WHICH ARE THE BUILDING BLOCKS OF THE CELL.
2)COLLECT ENERGY FROM THE SUNLIGHT TO PRODUCE FOOD FROM THE CELL.
3)PROVIDES MOST OF THE CELL'S ENERGY.
4)REGALUATE WHICH SUBSTANCE CAN ENTER OR EXIT THE CELL.

3) Provides most of the cells energy

Explanation:

The main functions of the mitochondria is to provide energy to most of the cells. Known as the (Powerhouses of The Cell), mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes. Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell. Mitochondria are also involved in other tasks, such as signaling between cells and cell death, otherwise known as apoptosis
