1. Signal Transduction Pathways start with a in the form of a message that is into within the cell. 2. Two types: a. Protein b. cascade: a phosphate that has is passed from one chemical to another until it eventually has an action. 3. Example with G-Protein in the Liver: a. Messenger:

1. Message; chemical; transduced; actions.

2. Protein modification; phosphorylation cascade; energy.

3. Signal Transduction Pathways (STP).

Explanation:

Transduction can be defined as a process which typically involves the change of a signal message contained in the outside of a cell to a message within or inside the cell.  

1. Signal Transduction Pathways start with a message in the form of a chemical message that is transduced into actions within the cell.

2. The two types of Signal Transduction Pathways (STP):

a. Protein modification.

b. Phosphorylation cascade: a phosphate that has energy is passed from one chemical to another until it eventually has an action.

3. An example with G-Protein in the Liver: is a signal transduction pathway (STP).

a. Messenger: docks with the receptor, specifically the G protein receptor.

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

this would be called the responsiveness
