The Mechanism of Insulin Biosynthesis by Pancreatic β-cells

The video tutorial explains the process of insulin maturation, detailing the roles of the rough ER and Golgi apparatus. It covers the transformation from preproinsulin to mature insulin, highlighting the importance of signal peptides, disulfide bridges, and the cleavage of the C peptide. The tutorial also discusses the secretion of insulin in response to glucose levels in the blood.

What are the three forms of insulin mentioned in the text?

What role do disulfide bridges play in the maturation of insulin?

Describe the process of how preproinsulin is generated and what happens to it in the rough ER.

Explain the significance of the signal peptide in the insulin production process.

What enzymes are involved in the cleavage of the C peptide from proinsulin?

What are the final steps required to convert proinsulin into mature insulin?

How does the level of intracellular calcium affect insulin release?
