How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan

Svetlanka [38]

Answer:

<u>18 molecules of </u> $CO_{2}$ <u />

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen → carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP
