Final answer:
Activated Akt promotes cell survival by inhibiting apoptosis and enhancing the expression of anti-apoptotic proteins.
Step-by-step explanation:
Activated Akt, also known as protein kinase B, promotes cell survival through various mechanisms. One of the main ways Akt promotes cell survival is by inhibiting apoptosis, which is programmed cell death.
Akt phosphorylates and inactivates pro-apoptotic proteins, such as Bad and caspase-9, preventing them from triggering cell death pathways. Additionally, Akt enhances the expression of anti-apoptotic proteins, such as Bcl-2 and Mcl-1, which help protect the cell from death signals.
