Exocytosis and Endocytosis 123 Free energy decreases during an exergonic reaction 155 In exocytosis, vesicles export large molecules 123 Free energy increases during an endergonic reaction 156 In endocytosis, the cell imports materials 123 Diffusion is an exergonic process 156 Cell Junctions 127 Free-energy changes depend on the concentrations of reactants and products 156 Anchoring junctions connect cells of an epithelial sheet 127 Cells drive endergonic reactions by coupling them Tight junctions seal off intercellular spaces between some to exergonic reactions 157 animal cells 127 Gap junctions allow the transfer of small molecules ATP, the Energy Currency of the Cell 157 and ions 128 ATP donates energy through the transfer Plasmodesmata allow certain molecules and ions to move of a phosphate group 158 between plant cells 129 ATP links exergonic and endergonic reactions 158 The cell maintains a very high ratio of ATP to ADP 159 Energy Transfer in Redox Reactions 159 6 CELL COMMUNICATION 134 Most electron carriers transfer hydrogen atoms 159 Cell Signaling: An Overview 135 Enzymes 160 Sending Signals 136 All reactions have a required energy of activation 161 Reception 137 An enzyme lowers a reaction’s activation energy 162 Cells regulate reception 138 An enzyme works by forming an enzyme–substrate Three types of receptors occur on the cell surface 138 complex 162 Some receptors are intracellular 140 Enzymes are specific 163 Many enzymes require cofactors 163 Signal Transduction 140 Enzymes are most effective at optimal conditions 163 Ion channel–linked receptors open or close channels 140 Enzymes are organized into teams in metabolic pathways 164 G protei
