Document Summary
Unit 4 calorimetry the fick equation & vo2 kinetics 1. Metabolism: the total of all cellular reactions (thousands) including all those concerned with synthesis of molecules (anabolic reactions) and breakdown of molecules (catabolic reactions) Bioenergetics: the process of converting the energy stored in chemical bonds in things like glucose or fatty acids into biologically usable form of energy (high energy bonds in molecules, e. g. atp) The immediate source of energy for muscular contraction is the high-energy phosphate compound atp. Structure: an adenine portion + a ribose portion + 3 linked phosphate. Formation: combining adenosine diphosphate (adp) + inorganic phosphate (pi) + energy. Atpase breaks the bond and energy is then released in thousands of different reactions to provide energy for processes including: synthesis, transport, work, heat, etc. A constant supply of atp is essential for the cell in order to match energy supply with energy demand.
