Hormones regulation and stimulation

Question 1

What are the 2 types of hormones?

Answer 1

Peptide and steroid

Question 2

What is a peptide hormone?

Answer 2

Peptide hormones are hydrofilic, polar and water soluble
They are big so they cant go through the cell memebrane so they have to bind to a receptor outside.

Question 3

Examples of peptide hormones?

Answer 3

FSH, Insulin and ADH

Question 4

What are steroid hormones?

Answer 4

Steroid hormones are derived from cholestrol so they are lipid soluble
They can bind to a receptor inside the cell instead of outside.

Question 5

What are examples of steroid hormones?

Answer 5

Testosterone and estrogen.

Question 6

How are FSH and LH stimulted to be released?

Answer 6

1. the pre optic nucleus release GN-RH
2. Which circulate the portal system to the gondadtrope cells the GN-RH stimulites it
3. Once it release FSH and LH
4. The lower levels of GN-RH it will make FSH and the higher levels of GN-RH it will make LH.

Question 7

How does the steroid hormone pathway work?

Answer 7

1. A steroid drug testoterone moves into the cell membrane and into the nulceus
2. Once in the nucleus it binds to the receptor, which will then displace the heat shock response
3. The receptor then becomes stronger and binds to the gene sequence such as hormone response element
4. This will then undergo DNA replication, transcription and protein for metabolism and protein synthesis.

Question 8

What is GN-RH,HRE and HSP?

Answer 8

Gondatropin releasing hormone
Hormone response element
Heat shock protein.
