What role does H20 have in cellular respiration

Marizza181 [45]

Answer:

$H_{2}O$ or Water is a very important component of the cellular respiration. However, it does not act in the process of cellular respiration directly, but is produced at the end of the cellular respiration during Oxidative Phosphorylation or Electron Transport System.

Basically, what happens is during the stages ETS, the NADH and $FADH_{2}$ gets converted into NAD and FAD whereas the $H^{+}$ ion accumulates into the inter-membrane space, which then passes through the ATP synthase molecule from the inter-membrane space to the matrix thus, stimulating the ATP synthase molecule to produce ATP the most important product of cellular respiration. This $H^{+}$ ion when enters the matrix gets utilized to form $H_{2}O$ by getting bound to $O_{2}$ . But if no $H_{2}O$ is produced in the final stage and the $H^{+}$ ion gets accumulated in the matrix then the cellular machinery will malfunction and the production of ATP will stop. Thus, by this fact, we know that $H_{2}O$ has a very important role in cellular respiration.

Which of the following is not a possible source of energy for chemosynthetic organisms? a. oil b. hydrogen sulfide c. methane d.

sweet [91]

Answer:

A: Oil

Explanation:

Chemo synthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy.

Bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide.

Chemo synthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances. Chemo synthetic bacteria, unlike plants, obtain their energy from the oxidation.

So Oil is not a possible source of energy for Chemo synthesis.
