Document Summary
Lecture 2 energy cant be created or destroyed---can only change from one form to another (northern light) the potential to do work defines energy in biological reaction energy produces heat--- input/output measured in joules/kcals. Pcr broken down only during exercise , needs creatine kinase during recovery, aerobically produced atp is used to replenish pcr stores forward reaction for initial exercise and reverse during recovery. 10 reactions to lactate before any energy is released way longer than pcr pyruvate to mitochondria to krebs-- to etc if we need atp immediately, pyruvate goes straight to lactate energy faster than aerobic pathway. Lecture 4: nad can accept hydrogens and regenerate in 2 ways. 2. shuttle systems to mitochondria lactate is a reduced cho with 80% of glucose potential energy can be used as fuel for st fibres in heart/skeletal (don"t need energy quickly, use aerobic/lactate as fuel)
