BIOL 1201 Lecture Notes - Lecture 5: Vasospasm, Blood Vessel, Leptin
Document Summary
When a platelet contacts a damaged blood vessel, it is stimulated to release thromboxane a2 thromboxane a2 in turns stimulates vascular spasm and attracts additional platelets to the injured site. In this example thromboxane a2 is acting as: The signal molecule leptin is a 16,000 da protein. Assuming there are 100 different cell signaling compounds in your body. If molecule a activates 100 molecules of b and b activates 100 molecules of c, how many molecules of c will be activate by 1 molecule of a. How many molecules can you get from epinephrine? (pic) Neither (bc the sunlight interruptions resets the clock and the pfr gets converting to pr instantaneously. To maintain constant levels of 3, if levels of 3 increases will a stimulate. If a releases more 1 does c produce more 3? (pic) If trh levels increase what happens to the levels of tsh. Acetylcholinesterase is an enzyme that destroys the neurotransmitter acetylcholine.
