Yes, Oxygen is needed by the body for aerobic cellular respiration. It is possible to use anaerobic respiration which is with out air, but it is must less efficient and produces lactic acid.
Our body needs oxygen gas to make energy and survive.
Oxygen is the gas needed by cells in the body for cellular respiration to produce energy. Cells take in oxygen from the bloodstream and use it to generate ATP, the energy currency of the cell, through a series of chemical reactions.
Oxygen is the gas needed during cellular respiration to release energy required for wound healing and skin graft integration.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
Plants need carbon dioxide in order to make their own food.
hi me know the anser but I is not telling u!!
Thermal Energy
heat of vaporization
if its combustable it releases energy when it burns
Usually heat is needed. but this can happen through osmosis as well.
The gas needed to release the energy stored in sugar is oxygen. During the process of cellular respiration, sugar (glucose) is broken down in the presence of oxygen to release energy in the form of ATP.
