Answer:
The correct relationship of is
Organic compound + O2 → CO2+H2O+Heat
Option B is correct one.
Explanation:
Aerobic Respiration happens in the mitochondria. Organic material glucose with the present of oxygen produced carbon di oxide,water and heat.
The chemical reaction is C ₆H ₁₂ O ₆ + 6 O ₂ --> 6 CO 2 + 6 H ₂ O +Heat+ ATP
The step involved in aerobic respiration are
Glycolysis.(Opens in a new window)(Opens in a new window) In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD⁺ is converted in NADH.
Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. There, it’s converted into a two-carbon molecule bound to Coenzyme A, known as acetyl CoA. Carbon dioxide is released and NADH is generated.
Citric acid cycle. The acetyl CoA made in the last step combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule.ATP,NADH and FADH₂ are produced, and carbon dioxide is released.
Oxidative phosphorylation. The NADH and FAH₂made in other steps deposit their electrons in the electron transport chain, turning back into their "empty" forms .As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.
