9.4 Hormonal Signaling in Multicellular Organisms

9.4 Hormonal Signaling in Multicellular Organisms

• amplification of a signal is an advantage of a signal transduction pathway.
• A single signaling molecule can lead to thephosphorylation of many, perhaps hundreds or thousands of targets.

• Each cell type has its own way of responding to a hormone.

• The schematic drawing on the left shows a neuron before it is exposed to cells via signal transduction pathways that control the functions, and the schematic drawing on the right shows the synthesis of specific proteins.
• The blue color indicates a low level of the amazing effects of hormones, yellow is an intermediate level, and purple is a high level.

• Epinephrine is a hormone that is produced from cells in the body.
• When cAMP is made, the fight changes its fluorescence as well.
• Within 20 seconds, there is an amount of cAMP.

• It prevents the production of saliva genes.

• Lungs relax the airway so more oxygen is taken in.
