Question

Cortisol binds with this receptor

This type of signal travels through the blood to reach its target cell

This type of signal diffuses through the plasma membrane and activates gene expression

Isoprenaline is a drug that is prescribed for an abnormally low heart rate. It binds with the adrenergic receptors on the pacemaker cells of the heart. This drug would be an __________of the receptor

This hormone is released from the anterior pituitary and binds with receptors in the adrenal cortex

This type of control is how EPI/NE and ACh control heart rate

A non-steroid hormone might cause one of these to open

Epinephrine and norepinephrine bind with this type of receptor

Insulin is the _____________ of the insulin receptor

This type of signal influences the same cell that released it

This hormone is released from the posterior pituitary gland and causes conservation of water

The binding of cortisol with a glucocorticoid receptor on the hypothalamus, reducing the secretion of corticotropin releasing hormone is an example of this process.

The normal action of EPI/NE is to increase heart rate. Propranalol is a drug that slows heart rate by binding to beta-adrenergic receptors. This type of drug is an______ of the receptor

This type of control is how EPI/NE control blood vessel diameter

This gland releases oxyticin and antidiuretic hormone

Answer 1

1)Cortisol binds with this receptor - glucocorticoid receptor.

Cortisol is a glucocorticoid hormone produced and released by adrenal gland. It has role in sympathetic activation during stress and has synergistic effect like glucagon.

Cortisol is a glucocorticoid thus it will bind to the glucocorticoid receptor.

2)This type of signal travels through the blood to reach its target cell - endocrine signal / paracrine signal.

There are four types of cell signalling - autocrine, paracrine, chemical and endocrine signalling.

Paracrine signalling is one in which a cell releases a molecule which binds to it's receptors present on near by cells and generate a local response.

3)This type of signal diffuses through the plasma membrane and activates gene expression - steroid ( chemical signalling)

Steroid hormones have their receptors present either in cytoplasm or nucleus. They are lipid soluble and hence crosses the plasma membrane to bind with their receptors present intracellularly.

4)Isoprenaline is a drug that is prescribed for an abnormally low heart rate. It binds with the adrenergic receptors on the pacemaker cells of the heart. This drug would be an agonist of the receptor

An agonist is a drug which will activate the receptor as the ligand which binds to it.

An antagonist is a drug which produces opposite action to that of ligand.

5)This hormone is released from the anterior pituitary and binds with receptors in the adrenal cortex - adrenocorticotropic hormone

ACTH hormone is released by anterior pituitary under the influence of corticotropin releasing hormone released by hypothalamus.

ACTH acts on adrenal gland and stimulates releases of glucocorticoids, mineralcorticoids and androgens.

This type of control is how EPI/NE and ACh control heart rate-

A non-steroid hormone might cause one of these to open - ion channels

Epinephrine and norepinephrine bind with this type of receptor - adrenergic receptor

Insulin is the agonist of the insulin receptor

This type of signal influences the same cell that released it - autocrine signal

This hormone is released from the posterior pituitary gland and causes conservation of water ,- antidiuretic hormone

The binding of cortisol with a glucocorticoid receptor on the hypothalamus, reducing the secretion of corticotropin releasing hormone is an example of this process - negative feedback.

The normal action of EPI/NE is to increase heart rate. Propranalol is a drug that slows heart rate by binding to beta-adrenergic receptors. This type of drug is an antagonist of the receptor

This type of control is how EPI/NE control blood vessel diameter - tonic control

This gland releases oxyticin and antidiuretic hormone - posterior pituitary

This type of signal diffuses through some interstitial fluid before binding with its receptor -
