What supplies the energy for most cellular functions?

The correct option would be Adenosine triphosphate or ATP.

Explanation:

ATP is adenosine triphosphate. The ATP for the cell is made within the mitochondria. Mitochondria is the energy factory or power plant of the cell. In the mitochondria, the process of cellular respiration produces energy.

The chloroplast use light energy to convert it in chemical energy and the mitochondria release this chemical energy by the process of cellular respiration.

ATP provides energy for most of the cellular reaction or functions.

Thus, the correct answer is the ATP or adenosine triphosphate.

doctors i believe if i'm wrong sorry

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.
