BIOL 1000 Chapter Notes - Chapter 8: Cyclic Adenosine Monophosphate, Glycogen, Adenylyl Cyclase
Document Summary
Commun. is responsible for controlled growth + develop. of animal. Cell communicate with each other in 3 ways: Small molecules and ions are exchanged directly between cytoplasm of 2 cells another cell. Gap junctions direct channel of communication in adjacent animal cells, between the cytoplasm of both cells. Gap junctions synchronize metabolic activities or electronic signals b/w cells in a tissue. Plasmodesmata direct channel of commun. in adjacent plant cells. Plasmodemata move small molecules, like plant hormones that regulate growth. Some cells have molec. on surface that allow direct interaction with. Some cells use surface molecules to recognize only specific molecules, preventing pathogens/ viruses. Cell adhesion molecules integral membrane proteins that allow cells to bind to other cells/ extracellular matrix. One cell (controlling cell), synthesizes specific signalling molecule to affect activity of another cell (target cell) The target cell is not on cell synthesizing signalling molecules, but it is nearby/distant from the controlling cell.
