Campbell's Biology, 9e (Reece et al.) Chapter 11 Cell Communication Students will encounter the topic of cell signaling repeatedly in this course and throughout their studies of biology. Therefore, the more confident they are regarding the basic principles, the more successful they are liable to be when encountering the topic. This chapter includes more higher-skill-level questions and makes connections to the principle of evolution as well as to other chapters of the text. Multiple-Choice Questions 1) Using the yeast signal transduction pathways, both types of mating cells release the mating factors. These factors bind to specific receptors on the correct cells, A) which induce changes in the cells that lead to cell fusion.

Concept 11.1 Local Signaling Cells may communicate by direct contact Animal cells Gap junctions Cell junctions Plant cells Plasmodesmata between cell plants Signaling substances can pass freely between adjacent cells Cell?cell recognition Paracrine signaling Short distances One cell can secrete some chemical or molecule that can then act on neighboring cells Example growth factors Stimulate adjacent cells to grow and divide Synaptic signaling Nerve cells in brain from one cell to another mostly an electrical signal Electrical signal triggers release of neurotransmitter Long distance signaling Endocrine signaling Hormones travels in bloodstream Target cell specifically binds hormone 3 stages of cell signaling 1 reception signaling molecule will combine to receptor

Lecture Outline for Campbell/Reece Biology, 7th Edition, ? Pearson Education, Inc. 11-1 Chapter 11 Cell Communication Lecture Outline Overview: The Cellular Internet ? Cell-to-cell communication is absolutely essential for multicellular organisms. ? Cells must communicate to coordinate their activities. ? Communication between cells is also important for many unicellular organisms. ? Biologists have discovered universal mechanisms of cellular regulation involving the same small set of cell-signaling mechanisms. ? The ubiquity of these mechanisms provides additional evidence for the evolutionary relatedness of all life. ? Cells most often communicate by chemical signals, although signals may take other forms.
