they depend on aerobic cell respiration
to obtain eAnaerobic organisms are those that livenergy for ATP production. (^)
or can live under oxygen-lacking
environments.
- What is the difference
between facultative anaerobic
beings and obligate anaerobic
beings?
Facultative anaerobic beings, like the
fungi Saccharomyces cerbrewing yeast, can survive uevisiae,nder a
oxygen-poor environments carrying out
fermentation. Havailable these beings carry out aerobicowever when oxygen is (^)
respiration.
Obligate cannot survive anaerobic bwhen oxygen is present.eings are those that
Some fungi, some agent of botulism Clostridiumbacteria (like the
botulinum, and the agent of tetanus,
Clostridium protozoans are exampltetani) and somes of obligatee (^)
anaerobes.
- What are the two types of
fermentation? What are their
chemical equations?
The two main types of fermentation are
alcoholic fermentation anfermentation. d lactic
In alcoholican intermediate fermentation molecule, is convertedpyruvic acid, (^)
into ethanol with liberation of carbon
dioxide. The alcohequation is as follows:olic fermentation
C 6 H 12 O 6 + 2 ADP + P --> 2 C 2 H 5 OH +
2 CO 2 + 2 ATP
In lactic fermentation pyruvic acid is
transformed into lacticno production of carbo acid and there isn dioxide. The
lactic fermentation equation is:
CATP 6 H 12 O 6 + 2 ADP + P --> 2 C 3 H 5 OOH + 2- In general what are the
reagents and products of
fermentation?
In fermentation glucose (sugar) is
degraded into pyglucose molecule ruvic acid (eacforms two pyruvic acidh (^)
molecules). In this process two
molecules of ATP are produced.
According to the type of fermentation,
pyruvic acid can pcarbon dioxide (in alcoholicroduce ethanol and
fermentation) or lactic acid (in lactic
fermentation). Tof fermentation in here are other varietieswhich pyruvic acid
can generate acetic acid (acetic
fermentation), pisopropanol (an alcohol tooropionic acid,), etc. T (^) he
type of fermentation depends on the
species of the involved organisms.
- Why in cake and bread
manufacture are alcoholic
fermenting organisms used
and not lactic fermenting
organisms?
Fermentation has the function of
making cakes and breads grow. This is
