Answer 1

The answer is C) mitochondria; oxygen

Adenosine triphosphate (ATP) is the main molecule for storing and transferring energy in cells. It is also called the energy currency of the cell.  ATP molecule composed of three phosphate groups. These phosphate groups are linked to one another by two high-energy phosphoanhydride bonds. ATP is produced in the mitochondria of all the living cell in the process of cellular respiration. During cellular sugar is oxidized in presence of oxygen to produce ATP.  

Answer 2

C) mitochondria; oxygen
