Steroid hormones

Postby 699133 » Mon Mar 08, 2010 11:38 pm

I cant figure this out for the life of me and I was hoping I could get some assisstance here.

Describe how a cell would produce and secrete a steroid hormone. Name and describe the functions of at least four cell structures that are involved.

Your help is very much appreciated!

What work have you done so far on this? What don't you understand? Post what you know or think you know and we'll take it from there.

Sorry, I forgot to mention that in my class we havent covered hormones at all. We briefly covered steriods but only as a type of fat and not what it does as far as cellular/bodily function specifically. So Im thinking should I just assume its talking about a generic fat and ignore the fact that its a hormone or vice versa? I think Im making this question more difficult on myself than it really is...

Ok, it's a start. You are right that steroids are lipids, or, more precisely, lipid-soluble, which means they can dissolve and move freely through other lipids. So, to lead you to the answers to your questions, two things for you to look up (in your book or using google/wikipedia):

1.) What common molecule are all steroid hormones based off of?

2.) What are cell membranes made of?

This will start you in the right direction, and probably give you at least 4 structures (depending on how specific you have to be about them). Hope this helps. :)

If you are still confused, or even if you think you have the answers you want, post them back here and I'll continue helping you get it or clarifying or confirming. Sorry for not just giving you the direct answer, but as a biology teacher, that's just not how I roll. ;)
