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.            

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
