Resource summary

Respiration
  1. Energy - the capacity to do work
    1. Active transport
      1. moving ions/molecules across a membrane against a concentration gradient
      2. secretion
        1. large molecules in cells exported by exocytosis
        2. endocytosis
          1. bulk movement of large molecules and particles into cells
          2. biosynthesis
            1. anabolic reactions producing large molecules
            2. replication
              1. events during cell cycle
              2. activation of molecules
                1. glucose is phosphorylated at the beginning of respiration
                2. contraction of myofibrils
                  1. movement of actin filaments over myosin filaments
                3. adenosine triphosphate - ATP
                  1. Adenine-base
                    1. ribose-pentose sugar
                      1. three phosphate groups
                        1. ATP production
                          1. Substrate level phosphorolation
                            1. ATP = ADP + Pi
                              1. Direct transfer from a substance with a phosphate group
                            2. Oxidative phosphorylation
                              1. ATP = ADP + Pi
                                1. as electrons are transferred along a series of carriers
                            3. different forms of respiration
                              1. Anaerobic respiration
                                1. aerobic respiration
                              2. energy is released from ATP then hydolised to ADP and inorganis phospate (pi)by the enzyme ATPase
                                1. respirsatory substrates - amino acids,glucose and fatty acids
                                2. energy from respirartion of glucose
                                  1. ATP
                                    1. energy available for cellular work
                                    2. ADP + Pi
                                      1. protein synthesis
                                    3. dehyrogenation
                                      1. removal of hydrogen
                                      2. Phosphorylation
                                        1. Addition of phosphates
                                        2. Decarboxylation
                                          1. Removal of CO2
