The compound that is reactant of both cellular respiration and dehydration synthesis is Glucose.
Glucose is a type of carbohydrate used as a source of energy by living beings, being one of the main nutrients of the cell. This monosaccharide also participates in the formation of complex carbohydrates, such as starch.
Glucose is obtained through food, and its amount in blood (glycemia) is regulated by the action of two hormones that act in the opposite way: insulin and glucagon. Both high and low levels of glucose can be harmful to the body.
