G Linked Receptors (Continued…….)
Serine/Threonine Protein Phosphatases Rapidly Reverse the Effects of A-Kinase
To Use Ca2+ as an Intracellular Signal, Cells Must Keep Resting Cytosolic Ca2+ Levels Low
Ca2+ Functions as a Ubiquitous Intracellular Messenger
Some G-Protein-linked Receptors Activate the Inositol Phospholipid Signaling Pathway by Activating Phospholipase C-b
Inositol Trisphosphate (IP3) Couples Receptor Activation to Ca2+ Release from the ER
Diacylglycerol Activates Protein Kinase C (C-Kinase)
Calmodulin Is a Ubiquitous Intracellular Ca2+ Receptor
Ca2+/Calmodulin-dependent Protein Kinases (CaM-Kinases) Mediate Most of the Actions of Ca2+ in Animal Cells
How do the Cyclic AMP and Ca2+ Pathways Interact?????
Mechanism of hormone action
CELL TO CELL COMMUNICATION Part 2. Transduction: Cascades relay signals Signal transduction involves multiple steps Multistep pathways can amplify a signal.

Signal Transduction Pathways
Signal transduction = conversion of a signal from one form into another. extracellular signals are converted into different biochemical forms, distributed.
Mechanisms of Cell Communication
Last Class: A. Membrane Proteins and their functions 1. membrane proteins are mobile yet organized 2. carrier and channel proteins B. Signaling Transduction.
Cell Communication Chapter 11. Types of Cell Signaling Local Regulators – molecules released travel short distances to other cells in the area Examples:
Chapter 11 Cell Communication. Cell Signaling Evolved early in the History of Life.
Cell Communication Chapter 11:. Why do cells communicate? Regulation - cells need to control cellular processes. Environmental Stimuli - cells need to.

Chapter 7 Cell Communication. Question? u How do cells communicate? u By “cellular” phones. u But seriously, cells do need to communicate for many reasons.

11.2 Reception: A signaling molecule binds to a receptor protein, causing it to change shape A receptor protein on or in the target cell allows the cell.
