B2- energy from respiration

HideShow resource information

aerboic respiration

  • takes place continuously in animals and plants
  • respiration: glucose+oxygen=carbon dioxde+water (and energy)
  • it takes place in the mitochondria of cells
  • energy released is used to:build larger molecules from smaller ones
  • enable muscle contraction
  • keep body temp constant and build proteins into plants
  • when investigating aerobic respiration we measure the amount of co2 produced by limewater
  • it is also possible to detect temperature rise

effect of exercise on the body

  • muscles need more energy because theyre contracting more
  • you need to increase the rate glucose and energy meet…
