AP Ch 7 Chapter  7 Review  Questions Different cell signaling mechanisms are used for short distance communication and long distance communication. Use the following mechanisms to complete the chart below and give an example of each: Synaptic Signaling, Autocrine Signaling, Paracrine Signaling, Endrocrine Signaling, Direct Contact Mechanism Example Short Distance Mechanisms 1. Direct Contact 2. Paracrine Signaling 3. Autocrine Signaling Long Distance Mechanisms 4. Endrocrine Signaling 5. Synaptic Signaling 6. Intracellular receptors can pass through the PLASMA MEMBRANE ______ because they are lipid-soluble or very small molecules. 7. Some intracellular receptors travel through the _ CYTOPLASM ___ to the nuclear membrane. 8. Once these intracellular receptors reach the nuclear membrane, they easily pass through a nuclear _ PORE _ and bind to the ___ DNA ______ to regulate ___ GENE EXPRESSION ____. Unit 2 2

AP Ch 7 Chapter  7 Review  Questions 9. Other intracellular receptors act as __ ENZYMES ____. For example, nitric oxide (NO) acts as a catalyst in the production of CYCLIC GUANOSINE MONOPHOSPHATE _ (GMP) which acts as a INTRACELLULAR _ _ MESSENGER _ _ MOLECULE __. 10. Most signal molecules, such as neurotransmitters, peptide hormones, and protein growth factors, are WATER __ _ SOLUBLE _. These can not pass through the plasma membrane, so they bind to _ CELL _ _ SURFACE __ _ RECEPTORS _. 11. Three superfamilies of cell surface receptors are:
