Cellular respiration , the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
What is a metabolic process that requires oxygen?
Aerobic Metabolism
Any metabolic process that requires oxygen to occur is referred to as aerobic. Humans, most other multicellular organisms, and some microorganisms require oxygen for the efficient capture of the chemical energy from food and its transformation into the cellular energy form known as ATP.
What metabolic process that requires oxygen called?
Metabolic processes that require oxygen are called aerobic . Metabolic processes that do not require oxygen are called anaerobic.
What is the term of process that does not require oxygen?
Cellular respiration that proceeds without oxygen is called anaerobic respiration .
What is a metabolic process similar to burning fuel?
A metabolic process similar to burning fuel, cellular respiration releases much of the energy in food to make ATP.
What type of respiration requires oxygen?
Aerobic respiration is a specific type of cellular respiration, in which oxygen (O 2 ) is required to create ATP.
How do you explain the oxygen cycle?
Oxygen cycle, circulation of oxygen in various forms through nature . Free in the air and dissolved in water, oxygen is second only to nitrogen in abundance among uncombined elements in the atmosphere. Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO 2 ).
Which step in cellular respiration uses oxygen?
Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy. This type of respiration occurs in three steps: glycolysis ; the Krebs cycle; and electron transport phosphorylation.
What kind of environment where oxygen is not used?
Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. Fermentation includes processes that use an organic molecule to regenerate NAD + from NADH.
Which type of respiration is most efficient?
Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration.
What type of respiration do humans have?
Respiration process that occurs in the presence of oxygen is called aerobic respiration , generally seen among humans. But in certain organisms like bacteria and algae, respiration occurs in the absence of oxygen, called anaerobic respiration.
Is respiration a metabolic process?
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Is metabolism a process?
Metabolism is the complex chemical process es your body uses for normal functioning and sustaining life, including breaking down food and drink to energy and building or repairing your body.
What is the final stage of respiration that produces the most ATP?
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
What kind of respiration happens quickly?
Anaerobic respiration occurs without oxygen and releases less energy but more quickly than aerobic respiration.
Does glycolysis require oxygen?
Glycolysis requires no oxygen . It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. ... Your muscle cells also add a fermentation step to glycolysis when they don’t have enough oxygen. They convert pyruvate to lactate.
