BSCI 207, Dr. Bretton Kent - Wednesday, August 29, 2018
Introduction
Physics defines how life evolves
Physiochemical Processes
Life exists in only certain boundaries
Many shapes are possible
Few occur
Morphospace- distribution of shapes where living systems actually exist
Physics and chemistry rule out many shapes
Everything an organism does is constrained by initial evolutionary
constraints
Thermodynamics
System- region of experimental interest
Closed- nothing enters, nothing leaves
Open- exchange of energy
All living systems
Surroundings- everything outside the system
Enthalpy (H)
Total energy of system
Order, random to organized
Gibb’s free energy (G)
Energy available to do work
Stops entropy
Entropy (S)
Measure of disorder in system
Correlated with heat content
Always wins
Energy is neither created nor destroyed
Energy can be transformed into another form
Both photosynthesis and cellular respiration create heat
Dictates energy balances
Change in free free energy = negative temperature multiplied by change in
entropy
Processes always reduce amount of free energy
Endergonic is positive change in free energy
Endothermic absorbs energy
Exergonic reactions reduces free energy
Exothermic releases energy
Spontaneous processes increase disorder
Instant cold pack
Spontaneous endothermic reaction
Nonspontaneous endergonic
