Imagine that a toxin is introduced to the body and inhibits the establishment of the proton gradient in the intermembrane space.
jarptica [38.1K]

Answer:

ATP synthase would be unable to produce ATP

Explanation:

ATP synthase depends on the proton gradient in the intermembrane space to enable it to produce ATP. As a consequence of this, the toxin will make it inactive. Oxidative phosphorylation is now inhibited in this case, as opposed to substrate-level phosphorylation.

Pyruvate is a product of glycolysis, and it will not be affected by a toxin. NADH is very important in the establishing of a proton gradient, so it is expected that it would be unable to be oxidized due to the toxin. Protons produced in the conversion of NADH to NAD+ actually establish the proton gradient. If the gradient is absent, NADH is then not likely to be oxidized.

A source from which organisms generally take elements is called
Anit [1.1K]

Answer:

A source from which organisms generally take elements is called exchange pool (option B).

Explanation:

Options for this question are:

  • <em>Food web.</em>
  • <em>Exchange pool.</em>
  • <em>Reservoir.</em>
  • <em>Biotic community.</em>

The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.

<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes cl
shtirl [24]

Answer:

Their cell walls are composed of very different biochemicals.

Explanation:

Biological classification is important to classify the organisms on the basis of their similarities and differences between them. Linnaeus is known as the father of biological classification.

Cellwall plays an important role in the maintenance of structure and function of the organisms. The composition of the cell wall of fungi, plants and prokaryotes are quite different. Plants cell wall made of cellulose, fungi has chitin in its cell wall and prokaryotes has different layers of cell wall.

Thus, the correct answer is option (D).
