Question

Kreb cycle short note in short points

Answer 1

Krebs cycle is considered as amphibolic pathway

it means, used for both break-down(catabolism) and build-up (anabolism) reactions.

Respiratory pathway is mainly a catabolic process which serves to run the living system by providing energy.

krebs cycle is the major pathway for the synthesis of reduced coenzymes and controlled release of energy during respiration.

The pathway produces a number of intermediates.

Many of them are raw materials for building up the both primary and secondary metabolites

Acetyl Co A is helpful not only in using fatty acids in krebs cycle but also raw material for synthesis of fatty acids, steriods, terpenes, aromatic compounds and carotenoids.

α-keto glutarate is organic acid which forms glutamate on amination

The Krebs Cycle, also called the citric acid cycle, is the second major step in oxidative phosphorylation. After glycolysis breaks glucose into smaller 3-carbon molecules, the Krebs cycle transfers the energy from these molecules to electron carriers, which will be used in the electron transport chain to produce ATP.
