Metabolism, Catabolism, Anabolism and Enzyme

Metabolism, Catabolism, Anabolism and Enzyme
  1. Metabolism is chemical reaction occurring in living organism
  2. Metabolism is distinguished into catabolism and anabolism
  3. Catabolism is a chemical reaction to break down bigger molecules into smaller ones' The reaction Tends to produced energy' For example is respiration'
  4. Anabolism is a chemical reaction to form bigger molecules from smaller ones' For examples is photosynthesis'
  5. Metabolism is influenced by enzyme
  6. Enzyme is an organic compound function as catalyzed it is composed of components of protein (enzyme) and non protein (prosthetic group)
  7. Enzyme has some characteristics, such as composed of protein, easily influenced by environmental change, as a catalyst, function specifically, active in reverse and required in small amount.
  8. Enzyme work by helping reacting the substrate which occurs in the actives side of enzyme. There are two hypotheses lock and key hypothesis and induced fit hypothesis.
  9. The factors influencing enzyme reaction rate are temperature, pH, inhibitor, and substrate concentration.
  10. Based on the work site enzyme is distinguished into endoenzyme and exoenzyme. Based on the way The enzyme works is distinguished into oxidoreductase transferase, hydrolase, lyase, isomerase and Ligase.
  11. Respiration is a process of energy release through chemical reaction by using oxygen (aerob) or without oxygen (anaerob).
  12. Aerobic respiration occurs in three stages, glycolysis, Krebs cycle, and electron transport.
  13. Anaerobic respiration through glycolysis and ends with alcohol or lactic acid synthesis.
  14. Photosynthesis is a process of using sunlight energy to convert water and carbon dioxide into food.
  15. Photosynthesis occurs in two stages' light reaction and dark reaction.
  16. some plant do preparation stages towards Calvin cycle which is known as C-4 pathway.
  17. Metabolism of carbohydrate, protein' and fat is interconnected to each other.
