The correct answer is Protein kinase activation Glucagon binding to a G protein-coupled receptor in the cell membrane
When the body requires energy during times of stress, fatty acids are released from adipose cells and mobilised. The process starts when glucagon and adrenaline levels in the blood rise and bind to specific receptors on the surface of fat cells. This binding action initiates a series of processes in the cell, culminating in the activation of yet another lipase, which hydrolyzes triglycerides in the fat droplet to release free fatty acids. These fatty acids enter the circulatory system and are given to the skeletal and cardiac muscles, as well as the liver. Fatty acids are attached to a protein called serum albumin in the blood, and they are taken up by cells in muscle tissue.
