Convert the energy of glucose into the usable energy of ATP.
A
Nucleus
B
Cell Membrane
C
Cytoplasm
D
Mitochondria
E
Vacuole
Explanation: 

Detailed explanation-1: -The process can be summarized as: glucose + oxygen → carbon dioxide + water. During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule.

Detailed explanation-2: -Glucose is converted into ATP by cellular respiration. One molecule of glucose produces 38 ATP molecules by aerobic respiration in the cytoplasm and mitochondria. The steps involved in cellular respiration are glycolysis, Krebs cycle, and oxidative phosphorylation.

Detailed explanation-3: -While we know that plants make their own glucose through the process of photosynthesis, plants still need mitochondria to convert glucose into usable energy.

Detailed explanation-4: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-5: -When glucose is converted to pyruvate by glycolysis, only a very small fraction of the total free energy potentially available from the glucose is released. In mitochondria, the metabolism of sugars is completed: the pyruvate is imported into the mitochondrion and oxidized by O2 to CO2 and H2O.
