1) Glucose undergoes glycolysis to produce pyruvate, generating 2 ATP and 2 NADH. Pyruvate then enters the mitochondria.
2) In the mitochondria, pyruvate is converted to acetyl CoA which feeds into the Krebs cycle, producing NADH, FADH2, and GTP.
3) NADH and FADH2 donate electrons to the electron transport chain, pumping protons across the membrane and generating large amounts of ATP through ATP synthase as the protons flow back into the matrix.
The respiratory system functions to oxygenate tissues and remove carbon dioxide through gas exchange. It consists of the upper respiratory tract including the nose and pharynx, and the lower respiratory tract including the larynx, trachea, bronchi, bronchioles and alveoli in the lungs. Oxygen diffuses into the blood in the alveoli while carbon dioxide diffuses out. Breathing is controlled by respiratory centers in the brain and involves inspiration through contraction of the diaphragm and expiration through relaxation.
