Answer:
The second stage.
Explanation:
Epinephrine is a hormone that is released by the glands over the kidneys that initiate a fight-or-flight response sequence in the body which starts with the segregation of the hormone and ends with the release of glucose into the bloodstream by the liver to provide energy required for the situation by the body.
The liver cells acts in the second stage of the epinephrine initiated signal with glycogen phosphorylase enzyme. The released epinephrine activates an enzyme called phosphorylase kinase and that in turn activates glycogen phosphorylase. Lastly glycogen phosphorylase reacts to epinephrine and releases another enzyme to remove the phospate from the glycogen phosphorylase group to form glucose that will be released into the bloodstream for energy.
I hope this answer helps.
The second stage. The liver cells act within the second stage of the epinephrine initiated signal with glycogen phosphorylase enzyme.
What do you mean by Liver cell?
Epinephrine may be a hormone that's released by the glands over the kidneys that initiate a fight-or-flight response sequence within the body which starts with the segregation of the hormone and ends with the discharge of glucose into the bloodstream by the liver to produce the energy required for the case by the body.
The liver cells act within the second stage of the epinephrine initiated signal with glycogen phosphorylase enzyme. The released epinephrine activates an enzyme called phosphorylase kinase which successively activates glycogen phosphorylase. Lastly, glycogen phosphorylase reacts to epinephrine and releases another enzyme to get rid of the phosphate from the glycogen phosphorylase group to create glucose that may be released into the bloodstream for energy.
Thus, the second stage of the signaling pathway associated with an epinephrine-initiated signal.
