19 maj 2020 · Aerobic Respiration. The recovery of energy through the oxidation of sugars in aerobic organisms is referred to as respiration. Essentially, hydrogen is progressively removed from glucose and is finally combined with oxygen to form water, while the other end-product from glucose is ‘hydrogen-free’ carbon in the form of carbon dioxide.
21 kwi 2024 · Microaerophiles need oxygen to grow, albeit at a lower concentration than 21% oxygen in air. Optimum oxygen concentration for an organism is the oxygen level that promotes the fastest growth rate.
A microbe that uses oxygen when available but can live anaerobically in the absence of oxygen is said to be a facultative aerobe. Those microbes that must have oxygen to survive are called obligate aerobes, while those that can grow only in the complete absence of molecular oxygen are called obligate anaerobes.
27 wrz 2021 · The reaction that harvests the energy of a sugar molecule in cells requiring oxygen to survive can be summarized by the reverse reaction to photosynthesis. In this reaction, oxygen is consumed and carbon dioxide is released as a waste product.

15 sie 2023 · Oxygen plays two roles in organisms: a structural role, being a part of most biomolecules (carbohydrates, proteins, nucleic acids) and a dynamic role, being an essential reactant in cellular respiration that is subsequently lost as water.
Microorganisms need oxygen for their propagation. Otherwise, they cannot survive or may switch to anaerobic growth with undesired products. The growth rate and metabolism of aerobic and facultative aerobic bacteria depend on the amount of dissolved oxygen.
