What makes a cell sensitive to a hormone or able to respond to it?
Cells can have many receptors for the same hormone but often also possess receptors for different types of hormones. In up-regulation, the number of receptors increases in response to rising hormone levels, making the cell more sensitive to the hormone and allowing for more cellular activity.
How can a cell respond to more than one hormone?
How can a cell respond to more than one hormone? It can have different receptors for different hormones.
How do hormones target specific cells?
Hormones activate target cells by diffusing through the plasma membrane of the target cells (lipid-soluble hormones) to bind a receptor protein within the cytoplasm of the cell, or by binding a specific receptor protein in the cell membrane of the target cell (water-soluble proteins).
What determines whether a particular cell is able to respond to a hormone what determines whether a particular cell is able to respond to a hormone?
What determines whether a particular cell is able to respond to a hormone? Hormones bring about their characteristic effects by altering target cell activity, increasing or decreasing the rates of normal cellular processes.
How can a target cell’s response to a single hormone molecule result in a response that affects a million other molecules?
How can a target cell’s response to a single hormone molecule result in a response that affects a million other molecules? This causes the response to be amplified at each step and results in a large amplification of the original signal. Some human diseases are associated with malfunctioning protein phosphatases.
What determines whether a specific tissue or organ responds to a particular hormone?
What determines whether a particular cell is able to respond to a hormone? the location of the cell. the presence of a specific hormone receptor. the structure of the hormone. the gland that releases the hormone.
Why can a signaling molecule cause different responses in different cells See Concept 11.4 page?
Why can a signaling molecule cause different responses in different cells? The transduction process is unique to each cell type; to respond to a signal, different cells require only a similar membrane receptor.
When a signal transduction pathway utilizes a phosphorylation cascade How does the cell’s response get turned off?
Such phosphorylation cascades carry a signal from outside the cell to the cellular protein(s) that will carry out the response. When a signal transduction pathway involves a phosphorylation cascade, how does the cell’s response get turned off? Protein phosphatases reverse the effects of the kinases.
How can a target cell recognize a particular hormone and not respond to other hormones quizlet?
How can a target cell recognize a particular hormone and not respond to other hormones? target cells respond to whatever hormone is present in the largest concentration.
Which of the following conditions is required for a target organ to respond to a particular hormone?
Hormones are chemical substances produced in one organ that are released into the bloodstream and affect the function of a target organ. Which of the following conditions is required for the target organ to respond to a particular hormone? The target organ must be the same as the organ that produced the hormone.
