Question

Order the following in the sequence of events after insulin binds to its receptor.

Answer 1

After insulin binds to its receptor, a series of events is triggered, including receptor dimerization, activation of a tyrosine kinase enzyme, exchange of GDP for GTP, and internalization of the insulin molecule in the cytoplasm.

Step-by-step explanation:

After insulin binds to its receptor, the following events occur:

1. The receptor forms a dimer.
2. A tyrosine kinase enzyme is activated.
3. GDP is exchanged for GTP.
4. The insulin molecule is internalized in the cytoplasm.

These events, triggered by insulin binding to its receptor, initiate protein activation cascades that result in various effects, including the translocation of Glut-4 transporter to the plasma membrane and the influx of glucose, glycogen synthesis, glycolysis, and fatty acid synthesis.
