G Proteins and the Body

The Nobel Prize in Physiology or Medicine 1994

G Proteins Make Sense Specific G proteins are found in retinal rods and cones
1. G proteins in our sense organs translate environmental information into a language that the G proteins in the brain can understand. 2. G proteins in the nose are activated by olfactory stimuli. 3. G proteins of the tongue register taste.


G Proteins Respond to Hormones

When in a rage our adrenals release adrenaline into the blood. When it reaches the liver glucose is formed, giving energy for fight or flight. The heart and the blood vessels also become prepared.
