What is aerobic respiration?

Listen to pronunciation. (ayr-OH-bik RES-pih-RAY-shun) A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.

What is the role of oxygen in aerobic respiration quizlet?

The purpose of oxygen in aerobic respiration is to donate the electrons that transform NAD+ + H+ to NADH.

Does aerobic respiration require oxygen?

Respiration using oxygen to break down food molecules is called aerobic respiration . ‘Aero’ means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration – it is the main respiratory substrate .

What is meant by aerobic and anaerobic respiration?

Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.

What is the role of oxygen in anaerobic respiration quizlet?

What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.

Why is aerobic and anaerobic respiration important?

Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen. Within the human body, both aerobic and anaerobic respiration are important to muscle function.

What is aerobic and anaerobic respiration?

Aerobic respiration is a fixed metabolic reaction that takes place in the presence of oxygen, going on in a cell to transform chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration in which the excessive energy electron acceptor is neither oxygen nor pyruvate derivatives.

What purpose does oxygen serve in aerobic cellular respiration?

The major role of oxygen in aerobic respiration is to synthesize the energy currency of the cell ATP by accepting electrons generated from the breakdown of the macromolecules present in the food. It can also be said that oxygen is essential for the breakdown of the macromolecules present in the food we ingest.

Which step of aerobic respiration does not require oxygen?

Glycolysis: Glycolysis is the first step in aerobic respiration. This step is actually anaerobic as it does not require oxygen. Each and every cell in the body, is able to carry out glycolysis in the cytosol (cell fluid of cytoplasm).

Does aerobic respiration release energy without using oxygen?

Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen . The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration, except, the process happens without the presence of oxygen.

What is the function of oxygen in aerobic metabolism?

Oxygen plays a key role in aerobic cellular metabolism, facilitating the conversion of glucose, protein, and lipids into usable energy. For every 6 molecules of oxygen used in the breakdown of glucose, 6 molecules of carbon dioxide are produced, along with water and adenosine triphosphate (ATP), according to the following equation:
