What happens first when the receptor protein changes shape in the cell signalling pathway for adrenaline?
it converts ATP into cyclic AMP
it activates a G protein
it activates protein kinases
it activates the enzyme adenylyl cyclase
|
What does adenylyl cyclase do in the cell signalling pathway for adrenaline?
it converts ATP into cyclic AMP
it catalyses the breakdown of glycogen into glucose
it activates protein kinases
it activates a G protein
|
What does cAMP do in the cell signalling pathway for adrenaline?
it catalyses the breakdown of glycogen into glucose
it activates the enzyme adenylyl cyclase
it activates a G protein
it activates many protein kinases via phosphorylation
|
What do protein kinases do in the cell signalling pathway for adrenaline?
they convert ATP into cyclic AMP
they activate the enzyme adenylyl cyclase
they activate enzymes that catalyse the breakdown of glycogen into glucose
they activate a G protein
|
How does glucose move out of liver cells in the cell signalling pathway for adrenaline?
by diffusion directly through the phospholipid bilayer
by active transport
by facilitated diffusion
by osmosis
|
What is the effect of one hormone molecule generating multiple cAMP molecules called?
division effect
multiplication effect
addition effect
cascade effect
|
What is the purpose of the cascade effect in the cell signalling pathway for adrenaline?
to maintain the same number of molecules involved
to eliminate the number of molecules involved
to decrease the number of molecules involved
to increase the number of molecules involved
|
In the cell signalling pathway for adrenaline, adenylyl cyclase converts ATP into cyclic AMP (cAMP), which acts as a messenger.
