What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?

Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.

What is said to be if it involves a pathway using oxygen?
Oxygen is transported first by air down the trachea and then transform to the hemoglobin of the blood to the cells. This is the pathway of oxygen in the human system.
What is heme biosynthesis?
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
What metabolic pathway generates 36 ATP from a single glucose molecule?
Glucose metabolism
What is a bio-geochemical cycle?
In geography and Earth science, a biogeochemical cycle (or substance turnover or cycling of substances) is a pathway by which a chemical element or molecule moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth.
How is lactose catabolized via the glycolytic pathway?
Lactose is metabolized by the enzyme beta-galactosidase giving one molecule of galactose and one molecule of glucose.
What is the pathway of an oxygen molecule from the nostrils to the parietal lobe of the brain?
1. nose 2. epiglottis trachea lungs bronchial tubes aveoli blood vessels osmosis hemoglobin blood heart left atrium valves left ventricle aorta arteries capilleries cells cell membrane osmosis cytoplasm mitochondria
Which metabolic pathway is common to both cellular respiration and fermentation?
The glycolytic pathway is common to both fermentation and cellular respiration. During the course of the metabolic pathway, glucose is broken down to pyruvate. In the presence of oxygen, the pyruvate molecule becomes involved in the TCA cycle. In the absence of oxygen however, fermentation occures. The process is brought about by an enzyme called alcohol dehydrogenase.
Is cellular respiration catabolism or anabolism?
Cellular respiration is a catabolic pathway because a complex molecule is being broken down.
A pathway by which a chemical element or molecule moves through both biotic and abiotic compartments of an ecosystem?
the Bio-geochemical cycle :P
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
