Cellular Respiration

Q. In digestion, we learnt that the glucose is absorbed by villi and transported to all the cells in the body. Given that glucose is a six carbon compound, it is broken down to______, a three carbon compound in every cell to release energy. This energy is utilized by the cells for bodily functions.
