Question

What is the difference between cellular respiration and tissue respiration?

Answer 1

Hint: External respirations the process of breathing that involves the lung and nose is the breathing process. It involves inhalation and exhalation of carbon dioxide, oxygen and other gases. Internal respiration involves gas exchange between the blood and body cells.

Complete answer:
Cellular respiration is a process of breaking down food into energy resources that involves many metabolic processes such as glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation to produce ATP.
Glycolysis: here the glucose is converted to pyruvate by a series of reactions and NADH and ATP is produced.
Pyruvate oxidation is the next step where the pyruvate from glycolysis is converted to acetyl -CoA inside the inner mitochondrial. In addition, carbon dioxide and NADH is released.
Citric acid cycle is the next step where acetyl-CoA undergoes a series of reactions and generates ATP, NADH, FADH and carbon dioxide.
Oxidative phosphorylation is the process where excess energy as in NADH, FADH is converted to ATP and later utilized.
Hence Cellular respiration is the process of producing ATP from glucose.
Tissue respiration is the exchange of gasses between the cell and lungs. This involves taking in oxygen and releasing carbon dioxide with the help of lungs.

Note:
Tissue respiration and cellular respiration both are related processes as intake of oxygen in tissue respiration helps in breaking glucose in cellular respiration and in the production of ATP.
