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]

In ecology, facultative and obligate are two terms used to describe organisms based on the mechanism of obtaining energy by each organism. Generally, organisms produce energy through cellular respiration. The three main types of cellular respiration are aerobic respiration, fermentation, and anaerobic respiration. The organisms that use either facu...
Facultative refers to the ability to live under more than one specific environmental conditions. The three types of facultative organisms are bacteria, fungi, and endoparasites such as protozoans and nematodes.
Obligate means be restricted to a particular characteristic. Obligate organisms such as bacteria, fungi, algae and endoparasites can be identified in nature. Most algae are obligate aerobes.
Facultative and obligate are two types of organisms categorized based on the types of cellular respiration the used to obtain energy.The three types of cellular respiration methods used by both facultative and obligate are aerobic respiration, anaerobic respiration, and fermentation.Both facultative and obligate can be bacteria, fungi or endoparasites.Definition
Facultative: Facultative refers to the ability to live under more than one specific environmental condition. Obligate: Obligate means to be restricted to a particular characteristic.
Types of Cellular Respiration
Facultative: Facultative organisms obtain energy from aerobic respiration, anaerobic respiration, and fermentation. Obligate: Obligate organisms obtain energy from aerobic respiration, anaerobic respiration or fermentation.
Types
Facultative: A single type of facultative organisms can be identified as facultative anaerobes. Obligate: Two types of obligate organisms can be identified as obligate aerobes and obligate anaerobes.
Jun 16, 2022 · An obligate aerobe is an aerobe that requires oxygen for aerobic respiration. Obligate aerobes need oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy. They use oxygen as the terminal electron acceptor during aerobic respiration. They have the advantage of yielding more energy than obligate anaerobes.
Obligate aerobes are organisms that need oxygen for their survival and multiplication example plants, animals, and fungi. Not all microbes are obligate aerobes; some have the ability to survive in ...
Bacteria, yeasts, fungi, and algae are capable of aerobic growth. The opposite of an aerobe is an anaerobe. An anaerobe does not require oxygen, or sometimes cannot even tolerate the presence of oxygen. There are various degrees of oxygen tolerance among aerobic microorganisms. Those that absolutely require oxygen are known as obligate aerobes.

Are obligate fungi aerobic or anaerobic?
Obligate aerobes require molecular oxygen in their metabolism, micro-aerophilic bacteria also require oxygen, but will not grow in an atmosphere containing 20% O 2 and will not grow under strict anaerobic conditions. Anaerobic bacteria do not require oxygen and may be described as facultative anaerobes if they are able to grow in either an aerobic or anaerobic atmosphere.
