Water (H2O), carbon dioxide (CO2), organic compounds, heat, and oxygen (O2) are all involved in aerobic respiration. Which of the following correctly describes the relationship between them?

A.) Organic compound + heat + CO2 → O2 + H2O
B.) Organic compound + O2 → CO2 + H2O + heat
C.) Organic compound + H2O → CO2 + O2 + heat
D.) CO2 + Organic compound → H2O + heat + O2
E.) CO2 + H2O + heat → Organic compound + O2

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.            

showing a photograph would make this a hell of alot easier

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
