Document Summary

Main topics: energy, regulation of cellular chemistry, free energy change, coupled reactions. Metabolism: total of all of a(cid:374) orga(cid:374)is(cid:373)"s che(cid:373)ical reactio(cid:374)s. Catabolic pathways (downhill): *catastrophe-broken down, break down complex molecules to simpler compounds. Anabolic pathways (uphill): *requires energy, consume energy to build complicated molecules from simpler ones. Thermodynamics: energy transformations that occur in a collection of matter. The rules: the energy of the universe is constant (principle of conservation of energy, every energy transfers or transformation increases the entropy of the universe. Spontaneous process: if a given process leads to an increase in entropy, that process can proceed without requiring an input of energy.

Things that affect enzymes: ph, temperature, amount of substrate (another word for reactant) Chapter 9: cellular respiration **key slides on powerpoint on what we need to know. Cellular respiration: convert chemical energy from nutrients into adenosine triphosphate (atp)
