Catabolism

None of the answers are correct

All answers are correct

Answer 1

The correct option is Anabolism.

All the reactions taking place in the living organisms are called metabolic reactions. These reactions are of two types:

1.Anabolic Reactions: These reactions occuring in the living organisns are those biochemical reactions by which small, simple molecules are linked to each other to make larger, complex molecules(, e.g. 6CO2 + 6H2O C6H12O6+ 6O2, PHOTOSYNTHESIS). These larger molecules are futher linked to give even larger molecules like alpha-glucose molecules are linked by glycosidic bonds to form starch, glycogen etc. amino acids are linked through peptide bonds to give peptides, fatty acid molecules are linked to glycerol to give lipids, etc. These reactions require energy mostly supplied by ATP hydrolysis. In photosynthesis energy is supplied by sunlight. These reactions lead to increase in mass of the organism. The pathways in which these reactions occur are called anabolic pathways and the phenomenon is called Anabolism.

2.Catabolic Reactions. These chemical reactions occuring in the living organisms are those by which large, complex molecules are broken down into smaller, simple molecules, (e.g.C6H12O6 + 6O2   6CO2 + 6H2O, RESPIRATION ). These break down reactions result in release of energy mostly stored in living cells as ATP. These reactions lead to decrease in mass of the organism. The pathway in which these reactions are occuring are called Catabolic Pathways and the phenomenon is called Catabolism.
