■ Essential to success in course
■ Can always ask questions
● Best Practices
○ Form study groups
○ Use missed exam as dropped grade
○ Stay with course material
○ Use math bench modules
● General
○ Course teaches biological thinking skills
■ Start broad and get narrow
○ Don’t worry about the details
● Grading
○ Three term exams, 100 pts. ea.
■ Lowest grade is dropped
○ Final exam, 150 pts.
○ Five explorations, 10 pts. ea.

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

Document Summary
Bsci 207, dr. bretton kent - monday, august 27, 2018. Tuesday & thursday 3:30-4:30 in mth b0425. Lecture outlines posted 24 hours in advance of lectures. Post all content related questions in class discussion. Bsci 207, dr. bretton kent - wednesday, august 29, 2018. 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. Energy can be transformed into another form. Both photosynthesis and cellular respiration create heat. 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. Bsci 207, dr. bretton kent - friday, august 31, 2018. No net change in distribution of molecules. Random movement resulting in movement of particle from high to low. Bigger molecules diffuse slower than small molecules. Uses diffusion in combination to achieve goal. Membrane potential due to different ion concentrations.
