Hint: When someone has vomiting and loose motions, the amount of water, salt and sugar in his body is decreased. So, the solution of sugar and salt is given to the person concerned to replenish the loss in his body.

Complete Answer:
- Yeah, I've heard the word glucose and I've seen it printed on the glucose powder packets.
I've seen it in a number of TV and newspaper ads, etc.
- Glucose is mainly produced by plants and most algae during photosynthesis from water and carbon dioxide, using sunlight energy, where it is used to create cellulose in cell walls, the most abundant carbohydrate.Glucose for metabolism is processed as a polymer, primarily in plants as starch and amylopectin, and in animals as glycogen.
- Glucose circulates as blood sugar in the blood of animals. The naturally occurring form of glucose is d-glucose, while l-glucose is produced synthetically in relatively small amounts and is of lesser importance.
- Glucose is naturally occurring and is present in its free state in fruits and other parts of plants. In animals, glucose is released from glycogen breakdown by a mechanism known as glycogenolysis.
- Glucose, as an intravenous sugar solution, is the safest and most effective drug needed in the healthcare system on the World Health Organization's List of Essential Medicines.

Note: Glucose was first extracted from raisins by the German chemist Andreas Marggraf in 1747. Glucose was found in grapes by Johann Tobias Lowitz in 1792 and was recognised as distinct from cane sugar ( sucrose). Since glucose is a basic requirement of many species, a correct understanding of its chemical composition and structure has greatly contributed to the general advancement of organic chemistry.
