What would happen if a hormone receptor did not bind to the right site?
I'm assuming you're asking what would happen if a receptor did not bind the proper hormone. The answer is a complex one because binding to a receptor does not necessarily mean that the receptor will be activated. Sometimes binding causes receptor inhibition; other times it can mean that the properties of the receptor change so that other hormones have an easier/harder time binding and activating it. But for the sake of giving an answer, let's say that we want to know what happens if a hormone binds and activates the wrong receptor. That answer is a relatively simple one: in most cases, the same events would take place that normally happen when the correct hormone binds the receptor. Let's take an example of a relatively uncommon cause of hypertension called hypertension exacerbated in pregnancy. In this condition, there's a mutation in the receptor for the hormone aldosterone that allows other hormones besides aldosterone (eg, progesterone) to bind it and activate it. When progesterone levels are high, as in pregnancy, the extra progesterone binds and heavily activates the aldosterone receptor, and the receptor essentially "thinks" that aldosterone has bound. So the action of progesterone at the aldosterone receptor are the same as aldosterone itself; since aldosterone is a major contributor to blood pressure, blood pressure increases to very high levels.
All human cells can bind or have a receptor for each hormone. True or False?
False. Not all human cells can bind or have a receptor for each hormone. Different cells express different types of receptors, allowing specific cells to respond to specific hormones.
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.
Why target cell respond to the hormone while others are uneffected?
Hormones are chemical messengers. In order to have an effect on a cell then it is necessary for the cell to have the correct receptor proteins. The hormone can bind to these receptor proteins and therefore will affect the cell.
A cell that contains proteins enabling a hormone to selectively bind to its plasma membrane is called what?
Target cell
What is most likely affected by a mutation in the DNA binding domain of a steroid hormone receptor?
The choices for this question were as follows:Conformational change of the receptorBinding of the hormone to the receptorTranslocation of the receptor to the nucleusCellular response to the hormoneThe answer is option 4.
Is a ligand a hormone?
yes a ligand is anything that can change the conformation of a receptor protein. hormones bind to proteins in the same way ligands do
What hormone receptors bounds to DNA even when the receptors is empty?
The glucocorticoid receptor (GR) is a hormone receptor that can bind to DNA even when it is empty. When bound to DNA, the GR can regulate gene expression and play a role in processes such as metabolism, inflammation, and stress response.
Does cholesterol function as a hormone receptor in the plasma membrane?
No, cholesterol does not directly function as a hormone receptor in the plasma membrane. Hormone receptors are typically proteins embedded in the membrane that bind specific hormones to initiate signaling pathways. Cholesterol primarily provides structural support and fluidity to the plasma membrane.
Why is the shape of hormone receptors so important in the human body?
The shape of hormone receptors is crucial because it determines the binding specificity between the hormone and the receptor. When a hormone attaches to its specific receptor, it triggers a signaling cascade that regulates various physiological processes in the body. The specific shape ensures that only the correct hormone can bind to the receptor, leading to a specific biological response.
What is the molecule called that can bind to a receptor protein?
The molecule that can bind to a receptor protein is called a ligand.
Which of these neurotransmitters does not bind to a plasma membrane receptor?
Nitric oxide does not bind to a plasma membrane receptor.
