Energy is also needed for these processes: growth, cell division, muscle contraction and protein synthesis.

growth - process of increasing in physical size

cell division - the division of a cell into two daughter cells with the same genetic material

muscle contraction - the activation of tension generating sites within muscle fibers.

protein synthesis - is the process where cells make proteins. This is done through transcription and translation.]]> 2020-04-27 01:28:28 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532125178 cecilia_beck https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532125838 2020-04-27 01:29:09 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532125838 cecilia_beck https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532137491 Sugar is one ingredient used in bread making. Yeast uses the sugar as a source of glucose and produces carbon dioxide during anaerobic respiration. Then, the carbon dioxide produced then causes the bread to rise.

This occurs when there is a shortage of oxygen. It releases less energy than aerobic respiration. This is because the oxidation of glucose is incomplete.]]> 2020-04-27 01:55:53 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532155497 https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532160099 Muscles and blood during vigorous exercise cause an oxygen debt. This is because lactic acid is built up in our tissues. This causes the burning and sore sensations in your muscles after anaerobic respiration. To get rid of the lactic acid, your body needs to react it with oxygen. The more lactic acid that is built up, the more oxygen is needed to react with it. This is called oxygen debt.]]> 2020-04-27 01:59:27 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532160099 https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532169274 Anaerobic respiration releases much less energy per glucose molecule than aerobic respiration. This is because the glucose is not completely broken down since oxygen is not used (oxidation is incomplete) therefore less energy is produced. ]]> 2020-04-27 02:07:18 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532169274 https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532174243 It is defined as a chemical reaction in cells that break down nutrient molecules to release energy. It does this by oxidizing the glucose to break it down into energy. The products of this reaction are carbon dioxide and water. Aerobic respiration produces more energy per glucose molecule as the glucose is broken down using oxygen (oxidation).]]> 2020-04-27 02:10:50 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532174243 https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532179157 glucose --> lactic acid

this lactic acid needs to be removed by reacting it with oxygen. This however causes an oxygen debt.]]> 2020-04-27 02:14:38 UTC https://padlet.com/cecilia_beck/795bjludmrqs45au/wish/532179157
