Document Summary

Rate goes up as a curve not as a straight line in relation to temperature -- Temperature is often a large limiting factor in all forms of life. The way that temp affects life is largely in physics thermodynamics. Molecular movement, greater speed, greater probability of collision. If you plot ln(rate) against 1/kt then you get a linear graph -- arrhenius function. Enables them to see how fit the data points were to a line. Use statistics to estimate the activation energy for various biochemical reactions because the slope of arrhenius function is (-) ae. Created the first way to estimate gas exchange through model organisms. Q10 -- measure at the rate of which temp would increase. Used for a century to determine how things responded to temperature. Optimal temperatures for reaction are lower at higher enzyme concentration. When the temperature gets too hot the enzymes denature -- reaction slows down// gets to zero.
