Biology Questions and Answers
Cell Respiration
- How do cells obtain energy
for their functioning?
Cells obtain energy for their metabolic
reactionsmolecules with h from the breaking of organicigh energetic content. (^)
This energy is mostly stored as ATP
molecules.
The process of obtaining energy in order
to produce ATP moleculcellular respiration. es is named
- What is the compound that
is phosphorylated for ATP
formation? What is the
resulting compound when ATP
liberates energy?
ATP, or adenosine triphosphate, is
formed after the binding of onephosphate (phosphorylation) to one ADP (^)
(adenosine diphosphate) molecule. This
is a process that stores eproduced ATP molecule. nergy into the
When ATP gmetabolism it loses one of itsives energy to the cellular
phosphates and ADP reappears.
ADP can also lose more phosphates and
generate AMP (adenosinemonophosphate) or even non-
phosphorylated adenosine. Adenosine

- What are the types of cell
respiration?
There are two typaerobic cell respiration, es of cell respiration:a reaction with (^)
participationand anaerobic cell res of molecular opiration, withoxygen (Out 2 ),
participation of molecular oxygen but
with otoxidant. Ther inorganic molhere are several varieties ofecules as (^)
anaerobic cell respiration, the main one
is fermentation.
- Under which conditions do
aerobic cells carry out
fermentation?
Some cells that usually ofrom aerobic cellular respiration btain energycan
carry out fermentation when oxygen is
not available.
There are bacteria and fungi that under
absence metabolicof oxygen use their anaerobic capability for energetic
supply. Muscle cells carry out
fermentation too when oxygen is scarce. - What is the difference
between aerobic and
anaerobic beings?
