Chapter 6, Problem 19CC
Summary Introduction
To determine: The way in which one chemical signal have opposite effects in two different tissues.
Introduction: In 1920, Walter Cannon explained several properties of the homeostatic control systems, and based on his understanding of working of control systems responsible for homeostasis, he proposed several postulates.

Which of the following statements is true?
Chemical messengers within cells are always the main determinant of the effector response.

Some blood vessels contain alpha adrenergic receptors that cause vasoconstriction in the presence of epinephrine, whereas others have beta adrenergic receptors that cause vasodilation in the presence of epinephrine.

- What accounts for the specificity of a cellular response to a signal molecule?arrow_forwardThe 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 nucleusarrow_forwardThis diagrams show the transmission of a signal through a network of neurons. How is a signal transmitted through one neuron to another?arrow_forward
- What is honest signaling? Describe one honest signal that you produce.arrow_forwardHow is the response to a signal regulated? Why is it often specific? Expain step by step in simple words please.arrow_forwardProteases are enzymes that destroy proteins. Application of these enzymes to an intact cell strips the proteins off the cell surface. If a specific signaling molecule is added to cells stripped of surface proteins and the cell still responds, what must be true of the signaling pathway? The receptor is a ligand-gated ion channel. The signaling molecule doesn't need a receptor. The signal can directly activate the second messenger system and does not need to activate the receptor. The receptor for this signal is inside the cell, and the signaling molecule is nonpolar and can diffuse into the cell.arrow_forward
- What prevents a nerve signal from travelling “backwards” towards the cell body?arrow_forwardSelect the correct order of signal transduction / cell communication / cell signaling. Reception - Response - Amplification Amplification - Reception - Response Response - Reception - Amplification Reception - Amplification - Responsearrow_forwardParkinson's Disease Parkinson's disease is neurodegenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. Describe the normal process of signal transmission at a synapse. Start with the arrival of an action potential at the axon terminal and include the name of the neurotransmitter that is affected by Parkinson's disease. Explain how the process is different in individuals affected with Parkinson's disease.arrow_forward
- Describe the four phases of signal transduction in living organisms.arrow_forwardWhat mechanisms in the cell terminate its response to a signaland maintain its ability to respond to new signals?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
