Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Uses energy from sugar to make energy for the cell
A
Chloroplast
B
Mitochondria
C
Nucleus
D
Cell Membrane
Explanation: 

Detailed explanation-1: -Mitochondria play host to one of the most important processes in your body, called cellular respiration. Taking in glucose and oxygen, mitochondria produce energy, which they capture and package as energy-rich molecules of ATP.

Detailed explanation-2: -In the mitochondria, the metabolism of sugars is completed, and the energy released is harnessed so efficiently that about 30 molecules of ATP are produced for each molecule of glucose oxidized. By contrast, only 2 molecules of ATP are produced per glucose molecule by glycolysis alone.

Detailed explanation-3: -Mitochondria break down sugar molecules and produce energy in the form of molecules of adenosine triphosphate (ATP). Mitochondria also help to maintain calcium concentrations, form blood components and hormones, and are involved in activating cell death pathways.

Detailed explanation-4: -Glucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. This releases energy (ATP) for the cell.

Detailed explanation-5: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).
