An amoeba gets energy in the same way that you do - from its food. An amoeba feeds by sending out 'bulges' of its cytoplasm, called pseudopodia, to surround a small food particle eg a smaller protozoan or an alga. The food, together with a small drop of the water is taken into the cell to become a food vacuole. Enzymes are then added to the food vacuole to digest the food. The soluble products of digestion are taken into the cytoplasm and used for respiration or growth. The release of energy from food is called respiration. Usually, the sugar called glucose is used by cells. Respiration usually involves 'burning' the food with oxygen. When this happens water and carbon dioxide are also produced: glucose + oxygen ---> water + carbon dioxide + ENERGY For a number of interesting articles about amoebae with photographs, go to: http://www.microscopy-uk.org.uk/full_menu.html Select Miscape article library, click on the Find icon and enter amoeba into the search box.
