accomplished by liberation of carbon
dioxide in alcogas passes throholic fermentation as thugh the dough and e
makes it grow. In lactic fermentation
there is no liberation and the desired result would not beof carbon dioxide
obtained.



  1. To what substance is the
    acidic flavor of fermented milk
    due?


Some bacteria ferment milk lactose by
lactic fermentation pThis product is responsiblroducing lactic acid.e for the acidic
flavor of yogurts, curd and milk.



  1. How can the knowledge
    about fermentation explain
    the origin of muscle cramps
    and pains after intense
    physical exertion?


A typical foxygen scarcityermentation pr happens in ocess due tothe muscle (^)
tissue. Under intense use muscles
demand too much consume much more oxygen to produceenergy (ATP) and (^)
that energy. High consumption leads to
oxygen scarcitybegin to make lactic and the muscle cells fermentation trying (^)
to satisfy their energetic needs. In this
situation mfatigue are due to the lacticuscle pain, cramps acid and
released by fermentation.



  1. How many ATP molecules
    are produced for each glucose
    molecule used in
    fermentation? How many ATP
    molecules are produced for
    each glucose molecule used in
    aerobic respiration?
    In fermentation from one glucose


molecule two ATP molecproduced. In aerobic respiration, ules are (^) a
much more productive process, from
one glucose molecare made. ule 36 ATP molecules



  1. Which is the cell organelle
    that is specialized in aerobic
    respiration?
    The cell organelles that are specializedin aerobic respiration are the
    mitochondria.

  2. Of which main compounds
    is the mitochondrion structure
    made?
    Mitochondria are organelles dtwo lipid membranes. The innerelimite d by
    membrane invaginates to the interior of


the organelle forming cristaedelimiting an internal space known as and (^)
the mitochondrial matrix.
