Glucose
One typology of sugar that it provides energy to plants and to animals. Glucose is a simple carbohydrate, or sugar. It is one of the four kinds of sugars. It is important because cells in an organism use it as a source of energy. Turning glucose into energy is called cellular respiration, which is done inside the cells of a living organism. Glucose is made by plants in a process called photosynthesis. It can also be made by animals in their liver or kidneys.

Having the right amount of glucose available in a person's body is important. It can be measured with a simple blood test. People that do not have enough glucose have low blood sugar levels. This is a health condition called hypoglycemia. People with too much glucose have hyperglycemia. They might have a health condition called diabetes.
