When Elisa has lower numbers of glucose molecules getting to her cells due to her diabetes, it causes her to feel tired because glucose is an important source of energy for the cells in our body.
1. Glucose is a type of sugar that serves as the primary fuel for cellular respiration, which is the process by which cells convert glucose and oxygen into energy.
2. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP (adenosine triphosphate), which is the molecule that provides energy for various cellular activities.
3. However, when Elisa's glucose levels are low, her cells receive less glucose to undergo cellular respiration. As a result, there is a decrease in ATP production, leading to a shortage of energy for her cells.
4. This lack of energy affects various bodily functions, including muscle movement, brain activity, and overall metabolism. Consequently, Elisa feels tired and may experience fatigue.
In summary, the reduced supply of glucose to Elisa's cells due to her diabetes impairs cellular respiration, resulting in a decreased production of ATP and a subsequent lack of energy. This, in turn, causes her to feel tired.
