What is the chemical formula for glucose, a simple sugar that serves as a primary energy source for living cells?

Explanation

Glucose, a simple sugar that serves as a primary and readily usable source of energy for the cells of most living organisms, has the chemical formula C6H12O6, indicating it contains six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. It is produced by plants during photosynthesis and is also the main sugar circulating in the bloodstream of animals, where it’s used directly for energy or converted into storage forms for later use. Blood glucose levels are closely regulated by the body, largely through the hormone insulin, to help maintain a relatively stable internal energy supply.
