Answer:
The right answer is The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.step explanation:
The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced. The correct option is D.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration:-
It is the breakdown of glucose molecules in the presence of oxygen to yield a large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Anaerobic Respiration:-
It is the breakdown of glucose molecules in the absence of oxygen and produces a small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
This process uses the respiratory electron transport chain as an electron acceptor instead of oxygen. It mostly occurs in prokaryotes. Its main advantage is that it produces energy (ATP) very quickly as compared to aerobic respiration.
The chemical equation of cellular respiration:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O+ ATP
In cellular respiration, glucose reacts with oxygen and produces carbon dioxide and water and the total number of atoms remains the same.
The number of oxygen, carbon, and hydrogen atoms on the reactant side is eighteen, six, and twelve respectively.
