What is the most important monosaccharide? __ (made during photosynthesis)

Answer explanation

The most important monosaccharide is glucose, which is made during photosynthesis. Glucose is the primary source of energy for all living organisms and is essential for cellular respiration. It is also the building block for many other carbohydrates, such as sucrose, maltose, and cellulose. Glucose is also used in the synthesis of proteins, lipids, and nucleic acids.
