3) Carbon Fixation : Carbon fixation is another example of anabolism because in photosynthetic organisms such as plants, cyanobacteria, algae and other photoautotrophic ogranisms fixate carbon dioxide into glycerate 3-phosphate which is then further converted into glucose. Beginning with photosynthesis, synthesis of carbohydrates from sunlight and carbon dioxide. This process uses ATP and NADPH produced by the photosynthetic reactions to convert CO2 into glycerate 3-phosphate. This shows anabolism because from a smaller simpler subunit of carbon dioxide, glycerate 3-phosphate is produced, a much larger and complex biochemical compound.
As we age, the balance slowly shifts towards a more catabolic dominant metabolism, initiating the many physical and energetic changes we associate with later stages of life. The body becomes less efficient, losing the ability to keep pace with the rate of break down that is occurring. This shift results in decreased energy levels, physical deterioration, increased susceptibility to illness and injury, and longer recovery times. While this is a natural process that everyone experiences, the choices we make over the course of our lives can greatly improve our body’s ability to age gracefully. A healthy lifestyle that includes proper diet, regular exercise, and good rest is essential.
