Answer :
Final answer:
An advantage of maltose being in the cell membrane and not secreted in pancreatic juice is that it can be readily transported into the cell for immediate use as an energy source, without the need for additional enzymatic breakdown. This allows for a more efficient uptake of maltose and better regulation of its concentration within the cell.
Explanation:
Maltose is a disaccharide composed of two glucose molecules linked together. It is an important source of energy for cells. In the human body, maltose is primarily broken down by the enzyme maltase, which is found in the small intestine.
There are certain advantages to having maltose present in the cell membrane rather than being secreted in pancreatic juice. Maltose in the cell membrane can be readily transported into the cell for immediate use as an energy source, while maltose in pancreatic juice would need to be broken down by enzymes before it can be utilized. This allows for a more efficient and rapid uptake of maltose by the cell.
Furthermore, keeping maltose in the cell membrane allows for better regulation of its concentration within the cell. The cell can control the amount of maltose present in the membrane, ensuring that it is available when needed for energy production. This arrangement also prevents excessive loss of maltose through secretion, conserving energy resources.
