When cyclic AMP phosphodiesterase is inhibited in a muscle that is stimulated by epinephrine,there will be a crucial effect of making the phosphorylase kinase to remain active,this active state of the phosphorylase kinase is because the associated protein kinase A will not be deactivated any longer.
Epinephrine signaling pathway has varying steps,but the preceding step occurs when the associating hormone binds to the receptor of the epinephrine in the cell surface,the receptor then changes shape when the hormone triggers it,this makes the receptor to move to it's active form. GDP( guanosine diphosphate) is released after the G protein ( guanine nucleotide-binding proteins) binds to the receptor that is activated,the G protein then takes up a molecule of GTP (guanosine triphosphate) .
Answer:
There are three stages of perception: selection, organization, and interpretation. In selection, the first stage, we choose stimuli that attract our attention. We focus on the ones that stand out to our senses (sight, sound, smell, taste, and touch).
Example: A person identifying anything in the car ir on the road that might affect their safety.
