The last electron acceptor gets clogged up and then the acceptor before it and so on until the quinnone pool and the few steps before it all have electrons but without anywhere to drop them off.
Insufficient oxygen supply to the cornea, basically.
angina
myocardial infarction
due to insufficient oxygen supply to blood stream.
any part of the body can die and never work again. That is what die means. It happens when there is insufficient blood supply (carries oxygen and nutrients).
Carbon monoxide is produced when a fuel is burning with an insufficient oxygen supply.
It means that there is an insufficient supply of oxygen in the artery. Artery carries oxygen away from the heart.
The process of burning wood in an insufficient supply of air or oxygen is called incomplete combustion. This leads to the generation of carbon monoxide instead of carbon dioxide, which can be harmful if inhaled.
Acute respiratory distress syndrome (ARDS) is a dangerous condition that causes insufficient gas exchange in the lungs, resulting in low oxygen levels in the blood. This can lead to respiratory failure and a lack of adequate oxygen supply to the body's tissues and organs.
It is the supply of oxygen to the heart; the oxygen is carried by the blood. When there's insufficient blood supply, oxygen supply is low too, and angina results. See http://en.wikipedia.org/wiki/Angina_pectoris
When Carbon reacts with an insufficient supply of oxygen, bonds form and create CO (carbon monoxide)
some bacteria,Animal cells also carry out lactic acid fermentation when oxygen supply is insufficient
