Many signal transduction pathways could
appear failry complex to students in introductory biology.
As you will see, once you recognize some common aspects
in all signal transduction pathways, they become easier
All signal transduction pathways display a common set
of components and sequence of events. One can identify
the general components and events of signal transduction
at different levels of biological organization, i.e.
at both the macro- and microscopic levels.
The popular game of pool is used in this topic as a
learning tool to understand the general components and
events of all signal transduction pathways
