plasma membrane receptors


How execute endocrine hormones reach their tarobtain cells? Select the finest answer.

Hormones take a trip with the lymphatic mechanism to target cells.

Hormones are released at synapses adjacent to target cells.

Hormones are transported through the blood stream to taracquire cells.

Hormones are developed by endocrine cells that are nearby to tarobtain cells.

Ducts transport hormones straight to tarobtain cells.


What is the function of activated protein kinases? Select the best answer.

Convert ATP to cAMP by phosphorylation.

Phosphorylate ADP to ATP.

Activate adenylate cyclase.

Phosphorylate proteins.

Degrade cAMP to AMP.


Cyclic AMP is degraded by __________.

AMP

protein kinase

phosphodiesterase

adenylate cyclase

G proteins


What is the device of activity of lipid-soluble hormones?

boosting protein kinases

activation of genes, which rises protein synthesis in the cell

phosphorylation of intracellular proteins


After a lipid-soluble hormone is bound to its intracellular receptor, what does the hormone complicated do?

phosphorylates a protein activates a protein kinase

directly changes protein synthesis at the ribosome

acts as a transcription aspect and binds to DNA, activating a gene


Which hormone’s receptor is constantly bound to DNA, also as soon as the receptor is empty?

thyroid hormone

insulin

cortisol


What keeps intracellular receptors from binding to DNA before a hormone binds to the receptor?

transcription factors

chaperone proteins (chaperonins)

Receptors can’t enter the nucleus until the hormone is bound to it.


Art-based Question

Both high blood glucose levels and low blood glucose levels are stimuli that cause certain responses by the body. These responses reason blood glucose levels to go back to their collection allude. In this activity, you will check out how this happens.

To testimonial how the body regulates blood sugar levels, watch this BioFlix animation: Homeostasis: Regulating Blood Sugar.

Part A - Regulating blood sugar. This diagram mirrors exactly how the body keeps blood glucose at a normal level.Drag each label to the proper place on the diagram.


A: Pancreas releases insulin

B: Body cells takes up more glucose

C: Liver takes up glucose and also stores it as glycogen

D: Blood glucose decreases to normal

E: Pancreas releases glucagon

F: Liver breaks down glycogen and releases glucose to the blood

G: Blood glucose retransforms to normal


Up-regulation involves the loss of receptors and prevents the taracquire cells from overreacting to persistently high hormone levels.

True

False


Which of the following occurs in instances wbelow even more than one hormone produces the very same results at the target cell and their linked effects are amplified?
