E N D
Receptor molecules • Located on the surface of cells • on the cell membrane
3-D view of receptor molecules • What kind of molecules are receptors? • Proteins
Cellular Communication • Receptor molecules are used so cells can interact
Receptor molecules are Proteins • They have a specific shape • Signals they receive must have a shape that can fit into them Receptor Signal
Primary Agents to Communicate • Hormones • Chemicals produced by nerve cells Receptor molecule
Which substances are found on cell surfaces and respond to nerve and hormone signals? 1.starches and simple sugars 2.subunits of DNA 3.vitamins and minerals 4.receptor molecules
Letter B indicates a 1.ribosomes 2.receptor molecules 3.tissues 4.inorganic substances
Base your answer on the diagram and on your knowledge of biology. Which statement best describes the diagram? • Nerve cell X is releasing receptor molecules. • Nerve cell Y is signaling nerve cell X. • Nerve cell X is attaching to nerve cell Y. • Nerve cell Y contains receptor molecules for substance A
Cellular communication is illustrated in the diagram below. Information can be sent from • cell A to cell B because cell B is able to recognize signal 1 • cell A to cell B because cell A is able to recognize signal 2 • cell B to cell A because cell A is able to recognize signal 1 • cell B to cell A because cell B is able to recognize signal 2 Cellular communication is illustrated in the diagram below. Information can be sent from 1.cell A to cell B because cell B is able to recognize signal 1 2.cell A to cell B because cell A is able to recognize signal 2 3.cell B to cell A because cell A is able to recognize signal 1 4.cell B to cell A because cell B is able to recognize signal 2
