a. Cells communicate by cell-to-cell contact.
b. Cells communicate over short distances by using local regulators that target cells in the vicinity of the emitting cell.
Essential knowledge 3.B.2: A variety of intercellular and intracellular signal transmissions mediate gene expression.
a. Signal transmission within and between cells mediates gene
b. Signal transmission within and between cells mediates cell
function.c. Signals released by one cell type can travel long distances to target
cells of another cell type.
Reflection- where we are at-
Big Idea 1: The process of evolution drives the diversity
and unity of life.
Big Idea 2: Biological systems utilize free energy and
molecular building blocks to grow, to reproduce, and to
maintain dynamic homeostasis.
Big Idea 3: Living systems store, retrieve, transmit, and
respond to information essential to life processes.
Big Idea 4: Biological systems interact, and these systems
and their interactions possess complex properties.

Cell Signalling Biology
This major contribution to the field of cell signalling by one of the world's leading experts, Professor Sir Michael Berridge (Cambridge) is now sponsored by the Biochemical Journal's Signal Knowledge Environment ensuring online access is freely available to all. Cell Signalling Biology provides researchers, teachers and students alike with an outstanding online resource describing the biology of cell signalling.
