21. In glycolysis, Glucose 6 phosphate is converted to fructose 6 phosphate which is do not coupled with ATP utilisation.

22. During differentiation, to form a tracheary element, the cells would form weak and elastic lignocellulosic secondary cell walls.

23. α-ketoglutaric acid → succinyl-CoA, coupled with the GTP production.

24. Protein is the most favoured substrate for respiration.

25. During differentiation, to form a tracheary element, the cells would form strong and elastic lignocellulosic secondary cell walls.

26. Splitting of water molecules is associated with PS II resulting in the release of O₂, protons and transfer of electrons to PS II.

27. Formation of 1,3 bisphosphoglyceric acid from glyceraldehyde-3-phosphate in glycolysis proceeds without any coupling to ATP utilisation.

28. The compounds that are reduced during respiration are known as respiratory substrates.

29. Cytokinins, exhibiting non-specific influence on cytokinesis, were originally identified as cytokine, a purine derivative of adenine, obtained from the fresh herring-sperm DNA.

34. α-ketoglutaric acid → succinyl-CoA, coupled with the CO₂ release.

35. 3-carbon PGA is then converted eventually to sugar by the Calvin cycle, and the RuBisCO is regenerated.

36. The breaking of the C-C bonds of simple compounds through reduction within the cells, leading to release of considerable amount of energy is called photosynthesis.
