Glucose gives us energy rapidly because our body easily and quickly digests and assimilates it.Glucose is obtained by the body through eating carbohydrates. In each gram of carbohydrates we consume, there are 4 calories worth of energy. Once ingested into the body, special enzymes in the digestive system break down the carbohydrates we have eaten into simple sugars called glucose.
