If you put a drinking straw in water, place your finger over the opening, and lift the straw out of the water, some water stays in the straw. Explain.
Chapter 11: Cell communication 2/29/16 Cell needs receptor to receive signal If receptor isn't in cytosol then nothing changes, if it is then it enterns through nuclear pore into nucleus Target gene DNA is what hornome receptor. Hormonegene bonding alters gene expression Every cell has the same DNA sequence, but it is the expression of these genes via the hormonereceptor complex that allows the gene to be expressed in the gene Signal processing Not all hormones/peptides can diffuse. Receptor protein embedded in lipid bilayer allow signal transduction pathway o Hormone binds to receptor, signal is sent through cytosol and amplified o G proteins: c
