What is the overall reaction for electron transport in mitochondria?

  • $C_6H_{12}O_6 + 4O_2 o 6CO_2 + 8H_2O$
  • $C_6H_{12}O_6 + 12O_2 o 6CO_2 + 12H_2O$
  • $C_6H_{12}O_6 + 6O_2 o 6CO_2 + 6H_2O$ (correct)
  • $C_6H_{12}O_6 + 3O_2 o 6CO_2 + 6H_2O$

    • What is the key difference between detritivores and decomposers?

  • Detritivores enrich soils, while decomposers recycle nutrients found in dead organisms.
  • Detritivores consume waste products, while decomposers consume living organisms.
  • Detritivores are scavengers, while decomposers are fungi and bacteria.
  • Detritivores consume non-living organic matter, while decomposers break down leaf litter and other non-living material. (correct)
