respiration

• aerobic respiration is a chemical reaction that releases energy that an organism can use
• respiration is an exothermic reaction
• aerobic respiration occurs in the mitochondria
• the equation for aerobic respiration is

  glucose + oxygen--> carbon dioxide + water + energy (ATP)
• aerobic occurs with oxygen and releases more energy but slowly while anaerobic occurs without oxygen and releases less energy but quickly
• anaerobic occurs in humans in the muscles during a large amount of physical work
• anaerobic equation in plants:

  glucose--> ethanol + carbon dioxide + energy (ATP)
• anaerobic respiration allows the plant to continue producing energy even when theirs a lack of oxygen (which happens in water logged soil)
• anaerobic respiration happens in the cytoplasm
• muscle cells cant continuously carry out aerobic respiration because when you exercise vigorously your hear may not be able to pump enough oxygenated blood to your respiring cells quickly enough to carry out aerobic respiration
• generalised anaerobic respiration equation

  glucose--> lactic acid + energy
• lactic acid causes muscle fatigue and soreness in the muscles
• fermentation is an anaerobic process that allows cells to generate energy in the absence of oxygen
• oxygen dept is a temporary oxygen shortage in the body tissues arising from exercise
