Students have asked these similar questions
The hormones known as "catecholamines" (adrenaline, noradrenaline, and dopamine) are not lipid-soluble.
Therefore their receptor sites are:
O a) On the inside of the plasma membrane
O b) On the outside of the plasma membrane
O c) In the cell cytoplasm
O d) In the cell nucleus
What is the main benefit of cell signaling via direct physical contact and cell signaling over short distances (ex: nerve cell signaling)?
How could we promote rapid or slow signaling for medical purposes?
So there are many examples of slow and rapid signaling via coupled receptors. For an example, salivary gland secretion is rapid signaling and cell growth is slow signaling. These pathways could be twisted and used to resolve medical issues in a more natural and less damaging way.
Are there any experiments that have or could be done to test out promoting rapid signaling to speed up slow processes such as cell growth in a severe wound?
What experiments have or could be done to test out slowing down signaling that is fast like cells responding to their environment negatively (over-active allergies)? Thank you.

- Which signaling molecule or molecules bind to a G-protein coupled receptor? (note: there may or may not be more then one answer) a) cortisol b) insulin c) glucagon d) calcium e) cyclic AMP f) epinephrinearrow_forwardOne such laboratory study investigated the binding of a hormone to three different receptor proteins in the cell membrane. The data collected are shown in the table below 1) Provide a brief explanation as to why ligand binding toproteins must be a reversible process. 2) Calculate the dissociation constant (Kd) for the hormone binding to each of the three proteins.arrow_forwardHormones are chemical signaling molecules produced by specialized cells and transmitted via the circulatory system to all other cells in the body. Which of the following describes a condition that needs to be met for a target cell to re- ceive the signaling molecules? A B с D The size and shape of the target cell needs to be similar to that of the cell that secreted the hormone. The location of the target cell needs to be within the local region of the cell that secreted the hormone. The target cell needs to have sufficient ATP to transport the hormone into the cell. The cytosol of the target cell has to have receptors that recognize and bind the hormone.arrow_forward
- What is the main benefit of cell signaling via direct physical contact and cell signaling over short distqnces (ex.: nerve cell signaling)?arrow_forwardThe binding of small amounts of hormones to target cell receptors triggers an intricate signal cascade. Why is the signal cascade necessary? Why not just have a simple molecularmechanism between the hormone and cellular effect?arrow_forwardWhat type of signal transduction is involved in signaling from hormones such as estrogen and testosterone? Explain the signal transduction pathway that occurs. 1. Is there a short term description for signal transduction, instead wrting multiple words to descripte the type of signal transduction? Can I just identify it as active signal transduction and inactive signal transduction. Based on my understanding, active singal transduction is for the fast react transdcution, while inactive signal transduction meanly refers the hormonal affacts on the system. 2. For Ion channels, specific enzymes are both involed activated and inactivated signal transduction?arrow_forward
- Testerone is a steriod (lipid) hormone. Which of the following would be the most likely receptor for this hormone? Select one: a. A transmembrane receptor in the cell membrane since it cannot diffuse across the cell membrane b. An intracellular receptor because it can diffuse across the cell membranearrow_forwardAlthough insulin initially acts through a tyrosine kinase receptor it also subsequently results in activation of a Ser/Thr protein kinase. Which one? A) Protein kinase A B) Protein kinase B C) Protein kinase C D) Ras E) Phosphoinositide-3-kinasearrow_forwardAfter a hormone binds to two receptor tyrosine kinases (RTKs), what is the very next step?arrow_forward
- Match each description with the appropriate receptorarrow_forwardHow could you determine whether a hormone-mediated response hasresulted from the intracellular mediator mechanism or the nuclearreceptor mechanism?arrow_forwardWhat fraction of estrogen receptors is expected to be free in the presence of an estradiol concentration of 1 nM assuming no other ligands are present? Enter your answer in decimal form. Fraction of free estrogen receptors = 0.0909 Incorrectarrow_forward
