Answer:
Correct Option - (d) Adenosine.
During acid analysis of living tissue, all of the following will be present in the retentate fraction except adenosine.
Explanation:
Acid analysis of the living tissue is done to find out the amount and category of acids present in it. The process includes grinding the tissues with trichloroacetic acid in a mortar and pestle. The grinding results in a soluble fraction and an insoluble fraction. The insoluble fraction is retained or left behind. This fraction is called the retentate fraction.
The retentate fraction or insoluble fraction has polysaccharides, proteins, nucleic acids, and lipids. Glycogen and starch are polysaccharides. Trypsin is an enzyme that comes under proteins. So, glycogen, starch, and trypsin will be a part of the insoluble acid fraction, i.e., the retentate fraction.
Adenosine is a part of nucleic acid. It is a nucleotide molecule. It is found in the acid-soluble fraction and not in the retentate fraction.
