Final answer:
The statement that adenosine is degraded by nucleotidases is true. Nucleotidases are enzymes that play a critical role in the metabolism of nucleotides by removing phosphate groups. The correct option is A.
Step-by-step explanation:
Adenosine is degraded by nucleotidases, which indicates that the statement is true. Nucleotidases are enzymes present in our body that play a critical role in the breakdown of nucleotides. These enzymes remove phosphate groups from nucleotides, transforming them into nucleosides.
The purine nucleoside adenosine is an important molecule in cellular metabolism, particularly as part of the structure of adenosine triphosphate (ATP) which is vital for cellular energy transfer. After its participation in metabolic reactions, adenosine can be further broken down by nucleotidases to its constituent components, which can be reused or excreted by the body.
