Document Summary

Leptin signaling: ability to respond to food. Wnt signaling: how we end up with morphology. Direct intercellular signaling ( rst picture: cell junctions allow signaling molecules to pass from one cell to another, gap junction and no receptors, ex: heart. Contact-dependent signaling (second picture: some molecules are bound to the surface of cells and serve as signals to cell coming in contact with them. Autocrine signaling (third picture: cells secrete signaling molecules that bind to their own cell surface or neighboring cells of the same type. Paracrine signaling (fourth picture: signal does not a ect cell secreting the signal but does in uence cells in close proximity (synaptic signaling) Endocrine signaling ( fth picture: signals (hormones) travel long distances and are usually longer lasting, enters bloodstream, ex: insulin. Shoot of g for cells postponing division. Nucleic acids a strand(s) of dna or. Gene a speci c segment of dna that contributes to a function.
