What are the main redox reactions in cellular respiration?
Glucose gains electrons through reduction while carbon dioxide loses those electrons through oxidation.
Glucose loses electron through oxidation while carbon dioxide gains those electrons through reduction.
Glucose loses electrons through oxidation while oxygen gains those electrons through reduction.
Glucose loses electrons through reduction while oxygen gains those electrons through oxidation.

Respuesta :

At the time of aerobic respiration, the oxygen is taken up by the cells and in combination with glucose generates energy in the form of ATP, and the cell expels water and carbon dioxide. This is an oxidation-reduction reaction in which glucose is oxidized and oxygen is reduced.

In the entire process of oxidation, glucose is losing one or more electrons to oxygen, and in reduction, oxygen is gaining electrons.

Thus, the correct answer is glucose is losing those electrons through oxidation and oxygen gains those electrons through the process of reduction.

In cellular respiration, glucose loses electrons through oxidation while oxygen gains those electrons through reduction.

CELLULAR RESPIRATION:

  • Cellular respiration is a process whereby living organisms obtain energy from food they ingest. The general equation of cellular respiration is as follows:

C6H12O6+ 6O2 → 6CO2 + 6H2O

  • In this reaction, glucose reacts with oxygen to produce carbon dioxide and water. This reaction is a redox reaction because it involves the transfer of electrons from one molecule to the other.

  • Glucose is the reducing agent meaning that it loses electrons to oxygen and becomes oxidized
  • Oxygen is the oxidizing agent meaning that it gains electrons from glucose and becomes reduced.

  • Hence, in cellular respiration, glucose loses electrons through oxidation while oxygen gains those electrons through reduction.
