Steroid hormone receptors inside the nucleus to allow steroid hormones to bind to them

Steroid hormones in place on the cell membrane to allow steroid hormone receptors to bind to them

Steroid hormone receptors in place on the nuclear membrane to allow steroid hormones to bind to them

Steroid hormones in place on the nuclear membrane to allow steroid hormone receptors to bind to them

Steroid hormone receptors in place on the cell membrane to allow steroid hormones to bind to them

Through intra-cellular receptors that activate the PLC pathway or the cAMP pathway

Through intra-cellular receptors that are GPRCs

Through membrane bound GPRCs and subsequent activation of 2^nd messengers

Through slow genomic pathways or fast non-genomic pathways

Through intra-cellular receptors or through membrane-bound receptors

breaks down Inositol tri-phosphate

inactivates Protein Kinase C

inactivates voltage-gated Ca++ channels

breaks down cyclic AMP

inactivates K+ channels

Acetylcholine competes to bind to the same G protein as noradrenaline, thereby reducing the available receptors for noradrenaline to bind to

Acetylcholine binds to the G protein causing a conformational change that prevents noradrenaline from binding

Acetylcholine binds directly to noradrenaline meaning it cannot bind to further receptors

Both neurotransmitters act on the same G protein that have differing effects on adenyl cyclase in the heart

They each activate a different G protein which in turn acts on adenyl cyclase in the heart

Is that using G protein coupled receptors located on the nuclear membrane 

Is that using ionotropic receptors located on the nuclear membrane 

Is that using G protein coupled receptors located on the cell membrane 

Is that where the receptors are already bound to the DNA

Is that where the receptors are quickly translocated by chaperone proteins to bind to the DNA

Calcium channel blockers

Potassium channel blockers

Nicotinic receptor antagonists

Dopamine receptor antagonists

Sodium channel blockers

Beta adrenaline

Only nicotinic ACh

ACh or NA

Only muscarinic ACh

Only ACh

Only interact with the DNA at specific sites called response elements

Together with the steroid hormone make up the response elements of the hormonal signalling pathways

Combine with the hormone to form response elements that bind anywhere in the DNA

Bind at specific sites of the hormone called response elements

Are  widely dispersed anywhere across the DNA
