Final answer:
Insulin secretion is not stimulated by hypoglycemia; it decreases insulin production to prevent further drops in blood glucose levels. Instead, secretion is stimulated by high plasma amino acids, high blood glucose, incretin, and parasympathetic nervous system activation.
Step-by-step explanation:
The question relates to the physiological conditions that stimulate or do not stimulate the secretion of insulin. Insulin is a hormone that plays a crucial role in regulating blood glucose levels. Its secretion is stimulated by various factors, but not by all physiological conditions. Hypoglycemia, or low blood glucose levels, is a condition that would not stimulate insulin production. In fact, when blood glucose levels drop, insulin secretion is decreased to prevent further lowering of glucose levels in the blood.
On the contrary, insulin secretion is stimulated by increased levels of blood nutrients, such as high plasma amino acids and increased blood glucose levels. Insulin facilitates the uptake of glucose by cells, promoting its use for energy or its storage as glycogen. Additionally, insulin secretion is influenced by certain gastrointestinal hormones, like incretin, which is released after eating and amplifies insulin release in response to glucose. Moreover, insulin secretion can be stimulated by the parasympathetic nervous system when activated, for instance, during the 'rest and digest' state, although this is less well-known than the direct stimulation by nutrients.
