                                According to the National Institutes of Health, glucose is the primary source of energy for the cells of most organisms, including humans and other animals. The process by which this crucial sugar is acquired from dietary sources is a fundamental aspect of biology, yet the mechanisms differ depending on an animal's diet and digestive system.
