Answer:
Iodine, or more accurately iodide (I-), is avidly taken up from blood by thyroid epithelial cells, which have on their outer plasma membrane a sodium-iodide symporter or "iodine trap". Once inside the cell, iodide is transported into the lumen of the follicle along with thyroglobulin.
Explanation:
The space under the lungs can be called as "Lung Volume" whereas force exerting by the atmosphere over an area is known as "Air Pressure"
When Contraction occurs in lungs, Volume of lung decreases, and as we know, volume is inversely proportional to Pressure, pressure inside lung increases, and expiration occurs [ Removal of gas from lungs to atmosphere ]
Now, when relaxation occurs, volume increases, pressure decreases, and inspiration occurs [ air travels from atmosphere to lungs ]

Respiration is the transformation of glucose to ATP, which is energy that the body can use.
Respiration consists of several steps: glycolysis, TCA/Krebs/Citric acid sycle and at last the oxidative phosphorylation.
The molecules needed for this to happen is water, oxygen (O2), NADH, ATP and glucose.
