students today we are studying chapter
biochemistry of cell in that we are
studying topic biosynthetic pathways
when I say biosynthetic pathways it
means the two major type of reactions
that take place inside human body or
sell those are anabolic reactions and
catabolic reactions.
anabolic reactions and catabolic
reactions there are previous reactions
taking place inside body but the two
major reactions are anabolic and
catabolic reactions when I say anabolic
reactions this means when similar or
simple biomolecules join to form complex
structures in simple language small
molecules assemble to form a complex
structure an example of this would be
acetic acid molecules when they join
together they form a complex structure
which is cholesterol anabolic reactions
are nothing but addition reactions in
simple and during anabolic reactions a
lot of energy is consumed energy is
consumed in the form of ATP or adenosine
triphosphate the next form of reactions
are catabolic reactions catabolic
reactions can also be called as
subtraction reactions or reactions
during which lack of energy is generated
or ATP is generated now during catabolic
reaction complex bio molecular
structures break down into simpler
structures that is a large volume latch
biomolecule structures are broken down
into smaller structures an example of
this is glucose that is formed during
the digestion process it is broken down
into lactic acid now glucose is c6h12o6
and lactic acid is a smaller biomolecule
so when you wait for food is converted
into glucose and if you don't consume
all the glucose prepared on that
particular day some amount of glucose is
stored in the form of glycogen into your
muscles and the next day if you need
that glucose source what body does is it
removes the glycogen spoken to the
muscles and in break downs into lactic
acid and then you can use lactic acid
into a source of energy so these are the
two major reactions that are happening
inside body anabolic reactions and
catabolic
basically catabolic reactions are both
energy generating reactions on in simple
language they are the reactions that
generate a lot of ATP or energy so let
us see anabolic and catabolic reactions
[Music]
biosynthetic pathways on pathways during
which energy is sent available an
example of this is catabolic reactions
catabolic reactions are basically when
complex biomolecular structures are
breaking down into simpler structures
basically large molecules are built in
down into smaller molecules an example
of this is glucose which is formed
during the process of digestion is
broken down when required into lactic
acid and used as an energy source ATP is
generated during this process a lot of
ATP is generated or energy is produced
during catabolic reactions which are
also called as subtraction reaction
anabolic reactions when simple
biomolecules join to form complex
structures basically in anabolic
reactions small molecules assemble to
make large molecules an example of this
is acetic acid when joins together forms
cholesterol a bigger biomolecule
anabolic reactions use a lot of ATP in
simple language energy is consumed
during this process a lot of ATP is used
during anabolic reactions so students in
this part of the chapter we have studied
about two types of reaction that is
anabolic reactions and catabolic
reactions I hope you are clear about
both the types of reactions thank you
