Organisms that do not use oxygen are known as anaerobes. They can be classified into two main types: obligate anaerobes, which are harmed or killed by oxygen, and facultative anaerobes, which can survive with or without oxygen but prefer anaerobic conditions. Anaerobes often thrive in environments such as deep soil, sediments, and the intestines of animals, where oxygen is scarce. Examples include certain bacteria, like Clostridium and Methanogens, which play crucial roles in processes like fermentation and methane production.
When there is no oxygen, or the organism cannot use oxygen for respiration.
a lack of oxygen
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
An organism that breathes a substance other than oxygen is known as an anaerobe. Anaerobes do not require oxygen for respiration and can use other substances such as sulfur or nitrogen compounds.
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
No, not every organism needs oxygen to survive. Some organisms, like anaerobic bacteria, can survive in environments with no oxygen or low oxygen levels. These organisms can use other substances, like nitrogen or sulfur, as alternative electron acceptors in their metabolic processes.
An organism that requires oxygen for its survival and metabolism is called an aerobic organism. These organisms rely on oxygen to produce energy through aerobic respiration.
The process that gives an organism oxygen is photosynthesis. During photosynthesis, plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is released into the atmosphere and is crucial for the survival of many organisms.
If the organism grows in the OF-glucose medium exposed to air, it is likely undergoing oxidative metabolism. This is because air contains oxygen, which the organism can use through oxidative phosphorylation to generate energy. If the organism were fermentative, it would generate energy through fermentation pathways even in the presence of oxygen.
The lungs take oxygen into the body and the blood transports oxygen throughout the body.
Plants are organisms that use carbon dioxide during photosynthesis to produce oxygen. They also use oxygen for respiration to break down sugars for energy.
Agar deeps are used to see whether an organism requires oxygen to grow. If there is spreading growth only at the bottom of the tube, the organism is an obligate anaerobe (meaning it cannot tolerate oxygen). If there is growth only at the surface of the agar, the organism is an obligate aerobe (it cannot grow without oxygen). And if there is growth all along the point of innoculation, the organism is a facultative anaerobe and can survive either way.
