BIOB34H3 Lecture Notes - Lecture 2: Temperature Coefficient, Collision Theory, Reaction Rate
Document Summary
Temperature is a measure of the average kinetic energy of the molecules of a substance. Ctmax is the max temperature you can expose to an animal before it dies. Aerobic scope, amount of energy it devotes to a particular exercise: a. s = max mr/smr. Heat, measure of total kinetic energy of the molecules of a substance. Collision theory: higher the temp, higher the rate of reaction, for a reaction to occur, collisions must occur with enough energy. Temperature coefficient: q10 = [r2/r1]^(10/t2 t1) temperature by 10, how many times does a reaction rate increase if you increase. Rate of reaction drops after 37 degrees c, because enzymatic proteins are denatured at this temperature and become non-functional, enzymes catalyze reactions. Induced fit model: enzymes need weak bonds to hug substrate, enzymes built-in regard to animal environmental temperature, weak enzyme bonds offer increased flexibility, temp preference of enzymes differs in different species.
