Chapter 28, Problem 28.40AP
Interpretation Introduction

Interpretation:

The three membrane-bound proteins involved in the transmission of epinephrine message across the cell membrane have to be named.

Concept Introduction:

  • Hormones: Hormones are chemical messengers which are secreted by the cell in endocrine system and are transported along the blood to stimulate the target cells having the corresponding receptors.
  • Epinephrine: Epinephrine is a hormone which is also called adrenaline. It is released when we have to respond immediately during a danger and hence is called fight-or-flight hormone. It increases the blood pressure, glucose level and heart rate of the body
  • There are three proteins which are involved in the releasing of a hormone signal. They are receptor, G protein and an enzyme

Place the following events in the proper order to describe the production of a second messenger from a G-protein. 1. Dissociation of G alpha from the beta and gamma subunits in the G protein complex 2. Ligand interaction with the G protein-coupled receptor (GPCR) 3. Recruitment of a G protein to the GPCR and replacement of GDP with GTP on the G alpha subunit 4. Conformational change in the G alpha a subunit causing a decreased affinity for the beta and gamma subunits 5. Activation of an effector, such as adenylyl cyclase to make CAMP, by the active G alpha subunit OA. 4, 5, 1, 2, 3 OB. 4, 3, 2, 1, 5 OC-3, 2, 1, 5, 4 OD. 1, 2, 3, 4, 5 OE. 2, 3, 4, 1,5 QUESTION 17 Kinases are essential in the cell because they directly OA. destroy IP3, turning off that signaling pathway. OB. phosphorylate proteins to cause conformational changes that change their activity. OC. directly activate translation. O D bind hydrophobic hormones in the cytoplasm to activate them. O E. bind and release calcium…
Please identify the incorrect statement about hormone signaling: A) Cystolic receptors bind to hydophobic hormones and transport them into the nucleus where they directly influence protein synthesis.  B) Hydropholic hormones cannot pass through the plasma membrane without help. Therefore, there are transport proteins that carry the hydrophillic hormones to the cytosol where it can bind its receptor  C) Hydrophilic hormone signalling involves membrane receptors that have the ability to activate adenylyl cyclase, producing cAMP. cAMP then affects the activity of numerous proteins in the cytoplam.  D) Hydrophobic hormones easily enter the plasma membrane. Therefore, there is no need for hydrophinic hormone receptors to be on the extracellular surface.
