Final answer:
The anticipatory release of insulin in response to glucose present in the stomach, which preempts an actual increase in blood glucose, is termed as feedforward control, differing from negative feedback control that responds after changes occur.
Step-by-step explanation:
The release of insulin in response to glucose in the stomach, which acts to increase glucose uptake and decrease blood glucose levels before an actual increase in blood glucose occurs, is described as feedforward control. This is different from negative feedback control, which would activate after blood glucose levels have already risen, serving to decrease those levels back to normal by enhancing insulin release. In negative feedback, high blood glucose is the stimulus that triggers insulin release, leading to decreased blood glucose, while in feedforward control, the body anticipates a rise in glucose and begins the response ahead of time.
The response described in the question is best described as negative feedback control. Negative feedback occurs when a change in a physiological parameter, in this case, blood glucose levels, triggers a response that counteracts the initial change and restores the parameter to its normal range. In the case of glucose in the stomach, the presence of glucose stimulates the release of insulin, which increases glucose uptake and decreases blood glucose levels. This response helps maintain homeostasis, which refers to the body's ability to maintain a stable internal balance.
