Cell Biology Objectives and Worksheet 2: Cell-to-Cell and Signal Transduction Name____________________ Objectives: Write out material in your course notebook. Cell to cell communication and signal transduction. Distinguish among types of cell-to-cell communication {autocrine, paracrine, endocrine, cytokine, cell surface markers, neurotransmitter} List major classes of receptors. Explain or diagram the specific structural components of the types. List and describe the components of signal transduction and the molecules involved. Write out specific second messenger signal transduction pathways (see tables 6.1 & 6.2). Define each of the following and predict their effect on signal transduction: agonist and antagonist for one receptor

Chapter 11 Cell Communication Overview: The Cellular Internet essential for multicellular organism the combined effects of multiple signals determine cell response Concept 11.1: External signals are converted into responses within the cell Evolution of Cell Signaling yeast cells identify their mates by cell signaling a signal transduction pathway is a series of steps by which a signal on a cell?s surface is converted into a specific cellular response pathway similarities suggest that ancestral signaling molecules evolved in prokaryotes and were modified later in eukaryotes Local and Long Distance Signaling the concentration of signaling molecules allows bacteria to detect population density cells in a multicellular organism communicate via chemical messengers

Mica Piro Chapter 11: Cell Communication External Signals are Converted to Responses Within the Cell (11.1) Evolution of Cell Signaling One topic of sell ?conversation? is sex?a type of yeast cell identify their mates by chemical signaling 2 sexes: a and ? Each type secretes a specific factor that binds to receptors only on the other type of cell When exposed to each other?s mating actors, a pair of cells of opposite type change shape, grow toward each other, and fuse/matethe new a/? cell contains all the genes of both original cells Once received by the yeast cell surface receptor, a mating signal is changed, or transduced, into a form that brings about the response of mating, which occurs in a series of steps called a signal transduction pathway

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.

Chapter 11 ? Cell Communication Overview: The Cellular Internet The trillions of cells in a multicellular organism must communicate with each other to coordinate their activities. There are networks of communication between cells ? can be very complicated There are Universal Mechanisms of cellular regulation (and communication) ? this is further evidence that all life is related (evolutionarily). 11.1 External Signals are converted to responses within the cell What do the cells say to each other? Evolution of Cell Signaling: One thing they talk about is sex/reproduction. Example: Yeast cells: (figure 11.2) There are two genders or mating types ? ?a? and ?alpha? Type ?a? cells secrete ?a? factor which can bind on specific receptors on the ?alpha? cell

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.
