Its purpose is to further the understanding of all aspects of the processes involved in the oxygen transport from the air to its ultimate consumption in the cells of the various organs of the body. ISOTT was founded in April 1973 by Duane F. Bruley, Ph.D., P.E. and James Haim I. Bicher, M.D. They also served as the first co-presidents of the ...
An obligate aerobe is an organism that requires oxygen to grow. [1] Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. [1] [2] In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain. [1]
[3] [5] [7] For example, methanogens grow at a redox potential lower than -0.3 V. [7] Sulfide is an essential component of some enzymes, and molecular oxygen oxidizes this to form disulfide, thus inactivating certain enzymes (e.g. nitrogenase). Organisms may not be able to grow with these essential enzymes deactivated.
Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
It is possible to introduce an artificial electron acceptor into the light reaction, such as a dye that changes color when it is reduced. These are known as Hill reagents. These dyes permitted the finding of electron transport chains during photosynthesis. Dichlorophenolindophenol (DCPIP), an example of these dyes, is widely used by experimenters.
A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood.It aims to provide an alternative to blood transfusion, which is transferring blood or blood-based products from one person into another.
One example of passive diffusion is the gas exchange that occurs between the oxygen in the blood and the carbon dioxide present in the lungs. [3] Facilitated diffusion is the movement of polar molecules down the concentration gradient with the assistance of membrane proteins .
In physiology, respiration is the transport of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the environment by a respiratory system. [1]
