ScienceASAll boards Created by: Marianne ShieldsCreated on: 03-01-13 10:58 Combustion fuel + oxygen -> carbon dioxide + water (+energy) occurs at high temperatures other products such as carbon dioxide and suet are made uses oxidation and reduction exothermic reaction 1 of 9 aerobic respiration glucose + oxygen -> carbon dioxide +water(+energy) C6H12O6 + 6O2 -> 6CO2 + 6H2O occurs at lower temperatures uses enzymes produces 38 ATP uses oxidation and reduction exothermic reaction 2 of 9 why is respiration important? sperm cell motility muscle contraction nerve impulse transmission uptake of ions (active transport) it provides us with energy! 3 of 9 what do we need to remove quicky in the blood? lactic acid- remove by continually breathing in oxygen (oxygen debt) carbon dioxide- carbon acid in blood, breathe out heat- removed by sweating 4 of 9 what can we measure in the blood? oxygen breathing rate- how many and how deep carbon dioxide heart rate- ECG, pulse lactic acid glucose 5 of 9 ATP ATP -> ADP + phosphate + energy ATP (energy currency) of the cell -> 2 sec Anaerobic respiration -> 20 sec Aerobic respiration -> long distance Creatine phosphatase -> 8 sec 6 of 9 Aerobic and Anaerobic respiration Aerobic respiration- takes place in the mitochondria glucose + oxygen ->carbon dioxide + water + 38 ATP Anaerobic respiration- takes place in the cytoplasm in the cell glucose -> lactic acid + 2 ATP 7 of 9 what happens to lactate? when oxygen is again available, lactic acid is converted back into pyruvate and then may enter the aerobic respiration cycle this takes place in the liver 8 of 9 respiration in muscle cells aerobic respiration- glucose -> pyruvate -> carbon dioxide + water 2ATP 36ATP anaerobic respiration- glucose -> pyruvate -> lactic acid (lactate) 2ATP 9 of 9
