Document Summary
Good signaling molecule: nitric oxide, dialation of blood vessels. Insulates cell from extracellular membrane b. b. ii. i. Single base change that affects a single amino acid in a receptor. Long axon i. ii: nt is released over a short distance b. c. b. Connectones: made of connexins, gap junctions, direct cytoplasmic between cells i. Acts on the same cells that have secreted it i: negative feedback. Production: made, mobilized, activated, inactivated rapidly, readily available precursors, rapid synthesis and decay iv. Signal transduction by identifying and understanding conserved: regulation of affinity/specificity. Phosphorylation: related functional domains in different proteins, masking and unmasking regions, causes the response. Acetylcholine b. b. b. b. b. a. b. But the different receptors effect the output of the response: output is due to gene expression in the cell. Takes gamma phosphate from atp and transfer it onto another i. target b. i. Phosphate groups don"t last very long a. b.
