What cell determine cell activities?
The binding of a hormone to a receptor is the first step. Target cell activation by hormone-receptor interaction depends equally on 3 factors. First the blood levels of the hormone, second ,relative numbers of receptors for that hormone on or in the target cells and the third ,strength of the binding between the hormone cell and the receptors.
Which hormone has intracellular receptors?
cortisol
Which type of hormone receptor-plasma membrane bound or intracellular- would be expected to provide the most long lived response to hormone binding and why?
Intracellular receptor responses would be longer since they create a hormone-receptor complex which stimulates the production of mRNA, which then creates proteins. This complex must be degraded over time. Also, the entire process takes longer.

How is hormone specificity achieved?
each hormone receptor only binds to one hormone
Do Hormones bind to receptor proteins with high capacity and low affinity?
Hormones do not bind to receptors with high capacity. The major defining properties of a hormone-receptor interaction, and what determines the strength of response is binding affinity and efficacy.
What determines if a cell is a target cell for a particular hormone?
If the signal molecule is able to fit through the cell membrane, it will bind to an intracellular receptor, if it cannot pass through the cell membrane, it will bind to an external membrane-surface receptor.
What does SERD mean?
SERD stands for Selective Estrogen Receptor Degrader. It is a type of drug that works by binding to estrogen receptors in cancer cells, leading to their degradation and ultimately reducing tumor growth in hormone-receptor positive breast cancer.
Steroid hormones produce their effects in cells by?
disguising themselves as the male sex hormone, testosterone, which can cause mood swings and other side effects
How many type of hormones and receptrs meet?
There are several different types of hormones and receptors that meet. The types are peptide hormone receptor, lipid-soluable hormone receptor, thyroid stimulating hormone, insulin hormone, leutinizing hormone, and many more.
How do hormones send messages?
The cells that react to a given hormone have special receptors for that hormone. When a hormone attaches to the receptor protein a mechanism for signaling is activated.
What is most likely affected by a mutation in the DNA binding domain of a steroid hormone receptor?
A mutation in the DNA binding domain of a steroid hormone receptor is most likely to affect the receptor's ability to bind to specific DNA sequences known as hormone response elements (HREs). This can impair the receptor's ability to activate or repress target genes and disrupt the normal functioning of the steroid hormone signaling pathway.
What factors control blood hormone levels?
the factors are: 1. The level of blood of hormone 2. The Numbers of receptors for hormone on the cell 3. The connection between the hormone to the receptor.
