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.
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called?
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called
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.
Name the cell that represents a chromophil depleted of hormone?
The cell is called a chromophobe cell. It appears pale and contains less cytoplasm than a chromophil cell due to a decrease in hormone content.
A hormone must target cells that have a receptor for it?
Yes, in order for a hormone to exert its effects on a cell, the cell must have specific receptors that can recognize and bind to the hormone. Once the hormone binds to its receptor on the target cell, it triggers a series of cellular responses that lead to the hormone's desired effects.
What determines if a cell is a target cell for a particular hormone?

How do signal molecules change how a cell will function?
Signal molecules act as a neurotransmitter or a hormone, which both effect how a cell functions.
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.
What recognize a hormone's chemical structure?
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
What are the possible results when a cell receives messages from two hormones at the same time?
A cell is a complex thing, and it can easily handle multiple messages, but if they are conflicting messages then the brain simply won't let the two hormones to be sent together. now if you are talking about a controlled experiment, the cell will decide, based on prior function of the cell, which one to follow, ie: if you send an estrogen hormone to a cell in the testicular wall, it probably wouldn't follow it, unless the cell is a mutated cell.
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called?
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called
Is a thyroid hormone a cell?
A hormone is a chemical, not a cell. They thyroid gland that secretes the thyroid hormone (which is called thyroxin) is composed of cells.
What is found in or on a hormone's target cell?
Hormone receptor
What determines whether a hormone will work or not?
A hormone's effectiveness depends on its ability to bind to specific receptors on target cells, which can be influenced by the receptor's presence, structure, and number. Additionally, the hormone's concentration in the bloodstream and the sensitivity of the target cells can impact its action. Factors such as the presence of antagonists or other regulatory molecules can also modulate the hormone's effect. Ultimately, the interaction between the hormone and its receptor dictates its biological response.
Why can you change only one manipulated variable?
Imagine you're doing an experiment in which you want to see the effect of an hormone in a cell culture. You have to control (know the values of the properties you are experimenting in) things like temperature, nutrient concentration, pH (acidity), etc. If you want to know if this hormone you are testing actually affects your cell culture, you must only vary this variable (e.g. hormone concentration mass/volume). If you, instead, change hormone concentration and pH, you may not be entirely sure if the effect you looked in your cell culture was caused by the hormone concentration or the pH. So, regardless methodological discipline, you can only vary one variable at a time.
When a hormone opposing the action of another hormone it is called?
antagonistic effect
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.
