4) cellular respiration allows organisms to release the energy stored in the chemical bonds of glucose, c6h12o6. the energy in glucose is used to produce atp, which cells use to supply their energy needs. during aerobic cellular respiration, oxygen is reduced and is produced as a by-product of this specific intermediate reaction. a) water b) ozone c) glucose d) carbon monoxide

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
