Jan 17, 2018 · Obligate: Obligate parasites only survive in the presence of the host. In a Liquid Medium. Facultative: Facultative organisms can be identified throughout the medium but, mostly near the surface. Obligate: Obligate aerobes can be identified near the surface of the medium. Obligate anaerobes can be identified at the bottom of the medium.
Jun 16, 2022 · Biology definition: 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 ...
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]
Apr 26, 2019 · Obligate Anaerobes Definition. Obligate anaerobes are organism which can only live in environments which lack oxygen. Unlike the majority of organisms in the world, these organisms are poisoned by oxygen. Obligate anaerobes are typically bacteria, and live in a variety of places naturally. Many obligate anaerobes live in the human body, in ...
Sep 25, 2023 · As an adjective, obligate means "by necessity" (antonym facultative) and is used mainly in biology in phrases such as: Obligate aerobe, an organism that cannot survive without oxygen Obligate anaerobe, an organism that cannot survive in the presence of oxygen Obligate air-breather, a term used in fish physiology to describe those that respire entirely from the atmosphere Obligate biped ...
Obligate aerobes cannot survive without oxygen as they rely on it for energy production. Many fungi, including some pathogenic species, are obligate aerobes. These organisms typically grow in environments rich in oxygen, such as soil and decaying organic matter. Obligate aerobes produce more ATP per glucose molecule compared to anaerobic ...

Apr 21, 2024 · The study of obligate anaerobes requires special equipment. Obligate anaerobic bacteria must be grown under conditions devoid of oxygen. The most common approach is culture in an anaerobic jar (Figure \(\PageIndex{3}\)). Anaerobic jars include chemical packs that remove oxygen and release carbon dioxide (CO 2). An anaerobic chamber is an ...
