Question
Chapter 11.4, Problem 3CC
Summary Introduction
To determine: The affect on the cell signaling pathways due to the activation of malfunctioning protein phosphatases.
Concept introduction: The mutation or the malfunctioning of the protein molecules will lead to a constant activation of the protein response without inhibition inside the cell. The function of the protein phosphatases is to remove the phosphate group from the protein signaling leading to an inhibition of the cell signaling pathway.

Based on the following description, draw the cell signaling pathway described (you only need to draw the pathway in one cell, but show the type of signaling described – you may need 2 diagrams). Compound X is released from cells in the pancreas and activates cells in the liver. What general type of cell signaling is this? When compound X binds its receptor on a liver cell, some of the amino acids (Y – one letter amino acid code) on the cytoplasmic side of the receptor are phosphorylated. Label what type of receptor this is. This leads to the receptor activating a cytoplasmic protein F which then activates a kinase K which then activates protein Z (diagram what is happening here – how is protein Z activated). Protein Z activation results in several genes being expressed. Label all your parts (don’t forget to label the ligand). Circle the signal transduction pathway and put a box around the cell response.arrow_forward

- More than 500 genes have been identified in the human genome that code for protein kinases. What does such identification imply regarding the role of protein kinases in cellular functions? Explain your answer.arrow_forwardFil in the blanks 1. A resting muscle fiber or neuron has an internal charge that is A. positive, B. negative, or C. neutral compared to the extracellular environment. This resting membrane charge is maintained by the A. calcium ion channels, B. sodium voltage gates, C. potassium voltage gates, or D. sodium/potassium pumps? . When a muscle fiber is at resting membrane potential there is a(an) "higher", "equal", OR "lower" concentration of sodium inside the cell compared to outside the cell and a(an) "higher", "lower", OR "equal" concentration of potassium inside the cell compared to outside.arrow_forwardWorking out the order in which the individual components in a signaling pathway act is an essential step in defining the pathway. Imagine that two protein kinases, PK1 and PK2, act sequentially in a kinase cascade. When either kinase is completely inactivated, cells do not respond to the normal extracellular signal. By contrast, cells containing a mutant form of PK1 that is permanently active respond even in the absence of an extracellular signal. Double mutant cells that contain inactivated PK2 and permanently active PK1 respond in the absence of a signal. Draw out the signaling pathway in a wild-type cell. What outcome is predicted for a double mutant cell with an activating mutation in PK2 and an inactivating mutation in PK1? Explain your reasoningarrow_forward
