Respiration

• What type of reaction is respiration?


  exothermic
• Whats the equation for aerobic respiration?

  glucose + oxygen -----> carbon dioxide + water
• Does aerobic respiration produce more or less energy?

  More
• Does anaerobic respiration produce more or less energy?

  Less
• Whats anaerobic respiraton equation?

  glucose -----> lactic acid
• What does anaerobic respiraton occur in?

  muscles, yeast and plants
• anaerobic respiraton for yeast and plants?

  glucose -------> ethanol + carbon dioxide
• What happens in respiration for yeast and plants?

  more ethanol produed, fermentation, used in making bread and drinks
• What does lactic acid do?


  Muscle fatigue, then stops efficent contraction, then oxygen debt leading to insufficent oxygen
• What does exercise lead do?

  insufficent oxygen and higher demand for energy
• What does a higher demand of energy lead to?

  Higher heart rate, breath volume and rate and supply of oxygenated blood is at higher rate
• Whats metabolism?


  Sum of all metabolic reactions in cell or organism- is a catabolic reaction
• Whats a catabolic reaction?


  Larger molecules broken down in smaller ones- excess protein broken down in urea in liver - lactic acid converted to glucose
• Whats the need for energy?

  heat to keep warm, movement and anabolic reactions
• Whats an anabolic reaction?

  Synthesis of lipids, amino acids and glucose
• Whats the synthesis of lipids?

  3 fatty acids and glycerol
• Whats the synthesis of glucose?

  cellulose, starch and glycogen
• Whats the synthesis of amino acids?

  making proteins and requires glucose and nitrates
