state one reason why the concentration of glucose in the blood decreases.

Concentration of glucose increases because glucose is converted to glycogen which is needed

One reason why the concentration of glucose in the blood decreases is due to the utilization of glucose by cells for energy production. As cells extract glucose from the bloodstream to meet their energy needs, the glucose molecules are broken down through various metabolic processes, such as glycolysis and cellular respiration. This leads to a decrease in the concentration of glucose in the blood.

To find this answer yourself, you can refer to basic physiological knowledge. Glucose is the primary source of energy for cells, and they constantly require it for their metabolic activities. Therefore, when cells actively consume glucose to fuel their functions, the concentration of glucose in the bloodstream decreases. This process is regulated by hormones such as insulin, which helps facilitate glucose uptake by cells, further contributing to reducing the blood glucose concentration.
