Two athlets Anju and Bina wanted to feel more energetic just before a 10m race. Anju drank some gluose and Bina ate a sandwich. Of the two, who would have actually felt more energetic?
Anju will feel more energetic as glucose is the simplest form of sugar and gets readily absorbed in blood and provides energy. On the other hand sandwich contains complex carbohydrates proteins etc which will take time to digest and provide energy.
