True of False: Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate
Murljashka [212]

Answer: False

Explanation:

Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.

It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.

It depends on the state of activity. It transports more oxygen to the tissue that require it the most.

Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .

Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.

The pathogen and human ribosomes is quite different. Human is a eukaryotes and contains the 80'S ribosomes whereas prokaryotes have 70'S ribosomes. In the preparation of the antimicrobial agents, the advantage can be taken as the bacteria or prokaryotes have different ribosome subunit. The drugs that can selectively target the pathogens ribosomes and stops the translation whereas shows no effect on human's translation.
