The Golgi complex participates in
1.) Fatty acid breakdown
2.) Formation of secretory vesicles
3.)Activation of amino acids
4.)Respiration in bacteria

The pK_(a1) and pK_(a2) of an amino acid are 2.3 and 9.7 respectively. The isoelectric point of the amino acid is:

The main steps involved in the process of translation are I.Activation of amino acid II.Initiation of polypeptide chain synthesis III.Termination of polypeptide chain formation IV. Transfer of polypeptide chain to tRNA

Which of the two statements together support that respiratory pathway is an amphibolic pathway , (i) Fats breakdown to glycerol and fatty acids, subsequently yields acetyl CoA (ii) In respiration C-C bonds of complex compounds breakdown through oxidation leading to release of energy (iii) Acetyl CoA from respiratory pathway is withdrawn for synthesis of fatty acids (iv) Proteins are degraded by protease to amino acids and enter the respiratory pathway
