Respiratory Substrates Energy values of respiratory substrates The energy value of a substrate is determined by burning a known mass of the substrate in oxygen in a calorimeter. Respiratory quotient (RQ) Examples of RQ values for different respiratory substrates
Introduction The Electron Transport Chain The electron transport chain is the final stage of cellular respiration, responsible for the production of ATP (adenosine triphosphate) and the formation of water molecules. Key points of the electron transport chain Practice question
The light-independent stage Reactions of the Calvin Cycle Practice questions Outline/ describe the main features/reactions of the Calvin Cycle.
The need for energy in living organisms Energy is needed for several processes in the body, including: The universal energy currency in all living organisms. The structure and synthesis of ATP Adenosine (a nucleoside) can be combined with one, two or three phosphate groups Metabolism All the biochemical reactions needed for an organism to stay…
