Respiration

Respiration : 

Respiration Glucose (6C) Pyruvic Acid (3C) Acetyl CoA (2C) ADP +Pi ATP NAD NADH NAD NADH CO2 GLYCOLYSIS: Occurs in the Cytoplasm Does not require oxygen (Anaerobic) Need 2 ATP to start Net gain of 2 ATP Citric Acid (6C) (4C) compound CO2 NAD NADH KREBS CYCLE: Occurs in the Central matrix of the Mitochondria. Requires Oxygen (Aerobic) A series of Enzymes produce Citric acid. NADH ATP ATP CYTOCHROME SYSTEM: Transfers Hydrogen into ATP 38 ATP molecules are made NADH from other stages passed to here Requires Oxygen. O2 H2O

Alternate substrates : 

Alternate substrates Other than CARBOYDRATES (glucose), FATS PROTEINS NUCLEIC ACIDS Can all be substrates during respiration

Anaerobic Respiration of Glucose : 

Anaerobic Respiration of Glucose In the absence of Oxygen: There is no NADH Hydrogen cannot pass through to the Cytochrome system Cytochrome system and Krebs Cycle cannot take place Only 2 ATP produced Pyruvic Acid can only be broken down further anaerobically Glucose (6C) Pyruvic Acid (3C) 2 ATP In PLANTS 2C ethanol + CO2 In ANIMALS 3C lactic Acid

Adenosine Triphosphate (ATP) : 

Adenosine Triphosphate (ATP) ATP is used in all cells to transfer chemical energy and so drive metabolic processes. It is used for: muscle contraction movement of cilia movement of sperm tails movement of the cell membrane during phagocytises active transport Movement of chromosome during meiosis... When ATP loses one of it’s phosphate groups (Pi) it becomes ADP
