Nutrition provides
cells with nutrients like glucose
respiration helps in the release of
energy from glucose some organisms need
oxygen to do this job, in that case it is
called aerobic respiration in aerobic
respiration one glucose molecule with
six carbons splits into two molecules of
pyruvate containing each three carbons
this happens in the cytoplasm of the
cell
these pyruvic acid molecules enters
mitochondria and turns to carbon dioxide
and water by releasing the energy in the
form of ATP.
ATPs fuels the different
endothermic reactions that takes place
inside these cells respiration takes
place in the absence of oxygen which is
called as an aerobic respiration then we
do vigorous exercise our muscle cells
get deprived of oxygen in such cases
glucose is converted to pyruvate and
which in turn gives out lactic acid and
energy in case of east an anaerobic
organism glucose is converted to pyruvic
acid pyruvic acid releases energy by
converting into ethanol and carbon
dioxide. This process is called
fermentation the energy released in
aerobic respiration is greater when
compared with the anaerobic respiration
but aerobic respiration requires a
continuous supply of oxygen. Plants have
stomata to exchange the gases with the
atmosphere whereas animals have special
respiratory organs to get the oxygen
from their surroundings
