Bioenergetics

• Plants use light for their source of energy
• Photosynthesis is an endothermic reaction
• what is the word equation for photosynthesis?

  carbon dioxide + water >>>>>>>> glucose+ oxygen
• The formula for carbon dioxide is C02
• the formula for water is H20
• The formula for glucose is C6H1206
• The formula for oxygen is 02
• As light intensity increases so does the rate of photosynthesis
• Respiration is a exothermic reaction because it releases energy
• what is the word equation for aerobic respiration?

  glucose+oxygen >>>>>>>>>> carbon dioxide + water+ energy
• Aerobic respiration releases a lot of energy because the glucose molecule has been fully oxidized.
• Muscle cells need a lot of energy for contraction
• Anaerobic respiration does not require any oxygen
• Anaerobic respiration releases much less energy than aerobic respiration
• In anaerobic respiration oxidation is incomplete
