Differentiate between catabolism and anabolism.
Solution
Metabolism requires a set of mechanisms that are used by all living beings to sustain their bodies. Both anabolism and catabolism involve these mechanisms. By freeing and capturing energy to keep the body going solid, both help organise molecules. These metabolism phases occur concurrently.
Complete answer:
The sequence of biochemical reactions that create molecules from smaller components is anabolism or biosynthesis.
Anabolic reactions are endergonic, meaning that they require and are not random input of energy to advance. Usually, anabolic and catabolic reactions are combined, with catabolism supplying the activation energy for anabolism. Many anabolic processes are powered by adenosine triphosphate ( ATP) hydrolysis.
Condensation and reduction responses are, in general, the mechanisms behind anabolism.
The series of biochemical reactions that break down complex molecules into simpler ones is called catabolism.
Thermodynamically, catabolic processes are favourable and random, so cells use them to produce energy or to fuel anabolism. Catabolism is exergonic, which means it releases heat and functions by oxidation and hydrolysis.
| CATABOLISM | ANABOLISM |
|---|---|
| A metabolic mechanism that breaks down bigger or smaller molecules. | Metabolic process that builds the necessary molecules needed by the body. |
| It releases energy. | It requires energy. |
| Adrenaline , cortisol , glucagon , cytokines are the hormones. | Oestrogen, testosterone, insulin growth hormone are hormones. |
| Catabolic exercises are aerobic and burn lots of calories | Anabolic exercises are anaerobic and help in muscle building |
| Examples include protein becoming amino acids , glucose | Examples include amino acids converted to proteins. |
| Requires oxygen | Do not utilize oxygen |
| Exergonic in reaction type | Endergonic in reaction type |
| Potential energy converted into kinetic energy | Kinetic energy converted into potential energy |
| It provides energy for anabolism and helps in muscle maintenance | It supports new cell formation and storage of energy |
Note: Anabolism occurs during photosynthesis in plants and as well as assimilation in animals.Catabolism occurs during cell respiration , digestion and excretion.
