Whether a molecule is oxidized or reduced in a redox reaction depends on its reduction potential relative to the available elect
ron donors and acceptors present that the organism can utilize. Given the following reduction potentials for various redox half reactions, in a lithotroph capable of utilizing ammonia as an energy source, which substances would be potential terminal electron acceptors for respiration?
Respiration with oxygen and some times nitrates as a terminal electron acceptor generates more energy than respiration with other terminal electron acceptors.
This plays out in anaerobic form of respiration when oxygen switches to nitrate respiration when oxygen is depleted but that denitrification in their preferred respiration pathway. Their metabolic adaptations allow some species to grow larger than predicted by cell physiology of aerobic organisms due to oxygen limitation. Nitrate is an important macronutrient, and denitrification is the main oceanic nitrate sink. Several postulations too can help to constrain biogeochemical models for marine nitrate cycling.
Having HIV/AIDS weakens your body's immune system. It destroys the white blood cells that fight infection. This puts you at risk for opportunistic infections (OIs). OIs are serious infections that take advantage of your weak immune system.
Metabolic acidosis is a condition that occurs when there are excessive quantities of acid in the body. Another cause is when the kidneys are not removing enough acid (H+) from the body because of the inability to form bicarbonate (HCO3−). Metabolic acidosis can lead to acidemia (low blood pH).
