Production and secretion are largely independent; prepared insulin is stored awaiting secretion. Both C-peptide and mature insulin are biologically active.
This means that glucose not only raises intracellular Ca 2+ via membrane depolarization, through K ATP channel closure, but also generates signals for insulin secretion independently of this K ATP channel closure.

Insulin clearance is implicated in regulation of glucose homeostasis independently of insulin sensitivity and insulin secretion. To understand the relation between blood glucose and insulin sensitivity, secretion, and clearance.

Insulin secretion is tightly regulated in healthy non-diabetic individuals, with both insulin gene transcription and exocytosis from insulin-containing granules responsive to rises in ambient circulating blood glucose.

Furthermore, visual representations like the one above help us fully grasp the concept of Independently Of Insulin Secretion.
Currently, seven classes of antidiabetic drugs exist, of which only three function without increasing circulating insulin levels and only one that definitively functions independently of insulin (Chaudhury et al., 2017). Restoring normoglycemia independently of insulin secretion or action...
Insulin secretion is a highly dynamic process regulated by various factors including nutrients, hormones, and neuronal inputs. The dynamics of insulin secretion can be studied at different levels: the single cell, pancreatic islet, whole pancreas, and the intact organism.
It outlines how insulin regulates carbohydrate, protein, and fat metabolism while highlighting its role in growth and how its secretion is influenced by nutrients and hormones. The document also addresses clinical implications such as diabetes mellitus and insulinoma.
