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
