The following points highlight the two main types of respiration enzymes. The types are: 1. Non-Oxidative 2. Oxidative. Type # 1. Non-Oxidative: Transphosphorylases: These enzymes catalyze transfer of phosphate group, from one kind of molecule to another, or form one carbon atom to other in the same molecule. The presence of magnesium ions is essential for the activity of some [...]
The following points highlight the two main pathways in intermeniary metabolism of carbohydrates. Pathway # 1. Gluconeogenesis: In this process glucose is formed from non-carbohydrate precursors. Thus, citric acid cycle and glycolysis are the main pathways of gluconeogenesis. The substrates can be some amino acids, (e.g., proline) lactic acid, glycerol, etc. Gluconeogenesis from amino acids and some organic acids is [...]
The following points highlight the two main forms of respiration among arthropods. The forms are: 1. Aquatic Respiration 2. Aerial Respiration. 1. Aquatic Respiration: The organs associated with aquatic respiration are: 1. Gills or Branchiae 2. Tracheal gills 3. Blood gills 4. Rectal gills 5. Book gills 6. Branchiostegite or gill cover 7. Epipodite and 8. Branchial basket. 1. Gills [...]
