Final answer:
Mitochondria are the organelles responsible for providing Jack with the energy needed to run around after eating candy bars through the production of ATP, the cells main energy-carrying molecule.
Step-by-step explanation:
The organelle most directly responsible for giving Jack the burst of energy after eating candy bars would be the mitochondria. Mitochondria are known as the "powerhouses" or "energy factories" of the cell, as they produce adenosine triphosphate (ATP), which is the main energy-carrying molecule used by cells for various functions including movement. The mitochondria generate ATP through a process called cellular respiration, where glucose from food is broken down using oxygen and in the process, carbon dioxide is produced as a waste product.
Jasmin's symptoms like extreme fatigue and muscle pain were due to mitochondrial problems, highlighting the critical role mitochondria play in energy production and overall cellular function. Eukaryotic cells like those of humans contain mitochondria, which are essential for supporting the energy requirements of active cells, such as muscle cells that contain thousands of mitochondria to meet their high energy demand.
