|
Aerobic cellular respiration is an oxidation reaction because it uses oxygen
|
|
|
Aerobic cellular respiration is an oxidation reaction because it takes away electrons from glucose
|
|
|
Aerobic cellular respiration is an reduction reaction because it reduces oxygen
|
|
|
Aerobic cellular respiration is an oxidation reaction because it does not require oxygen

Detailed explanation-1: -Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.
Detailed explanation-2: -Detailed Solution. The correct answer is 3 i.e. complete breakdown of food occurs in this respiration. Aerobic respiration: The respiration which uses oxygen is called aerobic respiration.
Detailed explanation-3: -Glycolysis. Glycolysis (which is also known as the glycolytic pathway or the Embden-Meyerhof-Parnas pathway) is a sequence of 10 chemical reactions taking place in most cells that breaks down a glucose molecule into two pyruvate (pyruvic acid) molecules.
Detailed explanation-4: -There is both loss and gain of electrons in respiration. Oxidation refers to electron loss, and reduction refers to electron gain. Here, glucose molecules are oxidized and oxygen molecules are reduced to generate water molecules. Therefore, it is called the oxidation-reduction or redox reaction.
