What else can I help you with?
Are endocrine cell associated with lipid soluble hormones?
Yes, endocrine cells are associated with lipid-soluble hormones, which include steroid hormones and thyroid hormones. These hormones easily pass through cell membranes due to their lipophilic nature and typically bind to intracellular receptors, leading to changes in gene expression. This mechanism allows for long-lasting effects on target cells. Examples of lipid-soluble hormones include cortisol and estrogen.
Do lipid soluble hormones travel in the bloodstream?
Yes, lipid-soluble hormones can travel in the bloodstream, but they generally do so bound to carrier proteins. Because they are hydrophobic, lipid-soluble hormones, like steroid hormones, do not dissolve well in water and therefore rely on these proteins to remain soluble and maintain their activity while circulating. Only a small fraction of these hormones exists in free form, which is the biologically active form that can interact with target cells.
What is the term for hormones that are lipid-soluble and can pass through cell membranes?
The term for hormones that are lipid-soluble and can pass through cell membranes is steroid hormones. This group of hormones includes hormones like estrogen, testosterone, and cortisol, which are derived from cholesterol and can bind to intracellular receptors to exert their effects.
It is impossible for water-soluble hormones to regulate gene expression since only lipid-soluble hormones can penetrate the cell membrane true or false?
false
Water-soluble hormones bind with their target receptors onin the and Acirc and shy?
Water-soluble hormones bind with their target receptors on the surface of the target cells, specifically on the cell membrane. This binding triggers a cascade of intracellular signaling pathways, leading to a physiological response. Unlike lipid-soluble hormones, water-soluble hormones cannot pass through the cell membrane due to their hydrophilic nature. Examples of water-soluble hormones include insulin and epinephrine.
A major determinant of a hormone’s mechanism of action is?
whether the hormone is water soluble or lipid soluble

What are steroid hormones soluble in?
Lipids (fat-soluble), they can therefore be administered orally.

Examples of water soluble and lipid soluble compounds in living organism?
Amino acid based hormones such as Human Growth Hormone is an example of water soluble compounds. Steroid hormones and thyroid hormone are examples of lipid soluble compounds in living humans.
How can all hormones be classified To which chemical group?
Hormones can be classified into three main chemical groups: peptide hormones, steroid hormones, and amine hormones. Peptide hormones, such as insulin, are made up of amino acids and are typically water-soluble. Steroid hormones, like cortisol and testosterone, are derived from cholesterol and are lipid-soluble. Amine hormones, which include thyroid hormones and catecholamines like adrenaline, are derived from single amino acids and can be either water-soluble or lipid-soluble, depending on their structure.
It is impossible for water-soluble hormones to regulate gene expression since only lipid-soluble hormones can penetrate the cell membrane true or false?
false
Do steroid hormones stay in the body longer than amino acid hormones?
Yes, steroid hormones generally stay in the body longer than amino acid hormones. Steroid hormones, which are lipid-soluble, can easily pass through cell membranes and often bind to intracellular receptors, leading to prolonged effects. In contrast, amino acid hormones are typically water-soluble, act more quickly, and are often broken down or excreted more rapidly from the body. This difference in solubility and mechanism of action contributes to the longer duration of steroid hormones' effects.
Some steroid hormones do not require a membrane receptor because?
they are lipid soluble and pass through the bilayer
Why can steroid and thyroid hormones but not amino acid-based hormones move across cell membranes?
Steroid and thyroid hormones are lipid soluble, allowing them to diffuse directly across cell membranes. Amino acid-based hormones are water soluble and require specific receptor-mediated mechanisms to enter cells.
