Question

Which protein kinase is activated as part of the PIP3 pathway?

a) Protein Kinase A
b) Protein Kinase B (Akt)
c) Protein Kinase C
d) Tyrosine Kinase

Answer 1

The protein kinase activated as part of the PIP3 pathway is Protein Kinase B (Akt), playing a crucial role in cellular processes like survival and growth.

Step-by-step explanation:

The protein kinase activated as part of the PIP3 pathway is Protein Kinase B (Akt). PIP3 specifically activates Protein Kinase B, also known as Akt, leading to various downstream effects that impact cellular survival, proliferation, and metabolism. This kinase is distinct from Protein Kinase A which is activated by cyclic AMP (cAMP), Protein Kinase C (PKC) which is activated by diacylglycerol (DAG) and calcium ions, and Tyrosine Kinase which is generally associated with receptor activation on the cell surface.
