Cellular respiration 1 st law of thermodynamics -energy can be freely transformed between different forms so long as the total energy is conserved (energy is neither created nor destroyed) goal of cellular respirations - break down of glucose- generate ATP for cellular work o accomplished by gradual release of electrons o generally transfer of H atoms Transform in the form of oxidation-reduction or redox reactions Oxidation and reductions - transfer of one or more electrons from one react to another - 1. Reductions- gain of one more electrons by an atoms, ion or molecule (reduced) - 2. Oxidations- loss of one of more electron (oxidized) some redox reactions - change the degree og electron sharing in covalent bonds - electrons move from less to more electronegative atom – lose potential energy – harvested for work organic molecules with high H content : - excellent fuels - bonds source of hilltop electrons- release energy when transferred to oxygen what is the main energy for genereation foods? Carbs and fats
