All living organisms break down sugar to obtain energy using cellular respiration, Which of the following chemical reactions rep
Ghella [55]

Answer:

The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy

Explanation:

Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.

<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:

              <em>              C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂ + ATP ↑</em>

<em>                Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>

This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.

The other reactions:

  • <em>oxygen + water </em><em>→</em><em> glucose + lactose </em>
  • <em>glucose + lactose </em><em>→</em><em> oxygen + water </em>
  • <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>

<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>
