Document Summary
Energy and metabolism: energy cannot be destroyed or created, entropy is always increasing, and energy is spread. Entropy = measure of how the energy is dispersed within system, order of randomness. G < 0, (-), is said to be spontaneous or exergonic: doesn"t indicate how fast -> [c], t, catalyst. A living organism, represents low entropy relative to surroundings, and does this by continually obtaining free energy from food. Most reduced (highest energy: least oxidized, electrons are gained, addition of h, removal of o. Rubisco co2 is fixed by the action of rubisco: essential in sustaining the earth"s biomass, all light energy goes through this. Chapter 2 water molecules and hydrogen bonds. Opposite charges neutralize positive o aligns with negative h. Each water molecule can participate in 4 h-bonds. Defined by the distance; measured in crystal chromatography. Hydrogen donors (+: n-h, o-h, s-h. Hydrogen acceptors (-: n, o, s electronegative items.
