What is the role of oxygen in aerobic respiration quizlet?
what role does oxygen play in aerobic respiration? Oxygen acts as the terminal electron acceptor in the electron transport chain of aerobic respiration. It gets the electrons from NADH and FADH2, which are produced in the Krebs cycle. by combining with electrons and protons, oxygen forms H2O.
What is the function of oxygen in aerobic respiration?
Oxygen is the final electron acceptor in aerobic respiration. It becomes water upon being reduced by the accepted electrons, which explains why water is one of the products of respiration.
Does aerobic require oxygen?
Aerobic respiration requires oxygen, as it takes place only in the presence of oxygen to produce energy.
Why does aerobic respiration stop without oxygen?
When no oxygen is present, the electron transport chain can't run because there is no oxygen to act as the final electron acceptor. This means that the ETC will not be accepting electrons from NADH as its source of power, so NAD+ will not be regenerated.
Is oxygen needed in anaerobic respiration?
Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors.
What is the role of oxygen?
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.
What is the role of oxygen in cellular respiration and photosynthesis?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

Why is oxygen needed in cellular respiration quizlet?
Why is oxygen needed for cellular respiration? Oxygen is used to bond with hydrogen to form water. NADH and FADH2 are made. Intermediate molecule with CoA (enzyme) enters the Krebs Cycle.
What is the role of oxygen in the body quizlet?
What role does oxygen play in the human body? Oxygen allows humans to burn food, creating energy. Every cell in the human body needs oxygen to survive. Cells turn glucose and oxygen into energy within their mitochondria, by a process called cellular respiration.
