Functional Anatomy and Pathophysiology I Dr. Frederick E. Williams Week 3 Lecture Notes ❖ Translation ➢ mRNA ➢ rRNA ➢ tRNA ■ Contains anticodon ■ With help from mRNA it brings amino acid into ribosome ❖ Enzymes ➢ Are protein catalysts ➢ Are not used or change shape after reaction ➢ Kinetics: ■ Vmax the max rate a reaction will occur at with enzyme present ■ Michaelis constant amount of substrate required to produce ½ the max reaction rate ■ Enzymes have initial rates that can increase until it hits either vmax, enzyme saturation or experiment end product inhibition ● Enzyme saturation when all active sites in an enzyme are occupied ● End product inhibition when the product of the reaction occupies active sites on enzyme ❖ ❖ Homeostasis ➢ Uses negative feedback to maintain balance ■ Negative feedback counteracts a stimulus ■ Positive feedback reinforces a stimulus ➢ Pathway: ■ Stimulus ■ Controlled condition is monitored by receptors ■ Sends signal to control center ■ Goes to effectors ■ Alters condition to obtain homeostasis ❖ Reflex is a response to a stimulus ➢ Reflex arch is the pathway impulses travel along to in order to create reflex
