Discuss “The respiratory pathway is an amphibolic pathway.”
Respiration
is generally assumed to be a catabolic process because during
respiration, various substrates are broken
down for deriving energy. Carbohydrates are broken down to glucose
before entering respiratory pathways. Fats get converted into fatty
acids and glycerol whereas fatty acids get converted into acetyl CoA
before entering the respiration. In a similar manner, proteins are
converted into amino acids, which enter respiration after
deamination.
During
synthesis of fatty acids, acetyl CoA is withdrawn from respiratory
pathway. Also, in the synthesis of proteins, respiratory substrates
get withdrawn. Thus, respiration is also involved in anabolism.
Therefore, respiration can be termed as amphibolic pathway as it
involves both anabolism and catabolism.
