Question

Tissue respiration denotes

• A. Respiration by tissues
• B. Gaseous exchanges between cell and tissue fluid
• C. Cell respiration
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

Tissue respiration refers to the exchange of gases between cells and tissue fluid which means diffusion of oxygen from pulmonary alveoli to blood and of carbon dioxide from blood to alveoli followed by transport of oxygen to and carbon dioxide from body cells. This process takes place in the cells of eukaryotes involving glycolysis and Kreb's cycle. Glycolysis is anaerobic breakdown of glucose which occurs in cytoplasm of cell and Kreb's cycle takes place in mitochondria.

Thus, the correct answer is option D.
