Summary Introduction

Introduction:

Ras is a small GTP binding protein that acts as link between the RTK (receptor tyrosine kinase) and the map kinase pathway.

Blurred answer
Students have asked these similar questions
a universal feature of cell signaling receptors is that they?   a. undergo a structural (shape) change when the signal molecule is bound   b. are present only in the plasma membrane   c. are only ion channels   d. are protein kinases   e. aer only nuclear receptors
Identify which of the following statements is a lie? Select one: a. The docking of ligands to the receptor causes receptor-associated proteins to activate another protein to continue the signaling cascade and one example of this event is the binding of epidermal growth factor (EGF) to the EGF receptor . b. Ligands are important to initiate signal Transduction pathway. c. Ligands detach from the cell surface receptor in order to change the conformation of the receptor and initiate the signaling pathway.
A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal? A. the hydrolysis of IP3 B. the hydrolysis of GTP C. the hydrolysis of PIP2 D. the hydrolysis of the hormone   I believe the answer is (B) the hydrolysisof GTP, because the G protein becomes inactive after GTP is hydrolyzed to GDP.  However, the solution provided by Bartleby is (C).  Please explain.  Thanks
