The absorption of glucose does not require energy. Glucose absorption occurs through facilitated diffusion, where glucose molecules move across the intestinal membrane down their concentration gradient with the help of transport proteins, such as GLUT2.

Glucose has covalent bonds.
The body regulates the absorption of water and glucose through the process of osmoregulation and hormonal control. Osmoregulation helps maintain the balance of water in the body by adjusting the amount of water absorbed in the intestines based on the body's hydration levels. Hormones like insulin and glucagon help regulate the absorption of glucose in the bloodstream by signaling cells to take in or release glucose as needed.
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.
