Question

Which of the following sets is most correct for the catabolism of an ${\mathbf{18}}$ carbon fatty acid?
(a) Mitochondria, beta-oxidation, $1140$ molecules
(b) Cytosol, beta oxidation, $146$ ATP molecules
(c) Mitochondria, beta oxidation, $146$ ATP molecules
(d) Cytosol, beta oxidation, $140$ ATP molecules

Answer 1

We know that Metabolism is the arrangement of life-supporting compound responses in living beings. The three fundamental reasons for digestion are: the change of food to energy to run cell measures; the transformation of food/fuel to building blocks for proteins, lipids, nucleic acids, and a few starches; and the end of metabolic squanders.

Complete answer:
Metabolic responses might be sorted as catabolic – the separating of mixtures for instance, the separating of glucose to pyruvate by cell breath; or anabolic – the structure up of mixtures like proteins, sugars, lipids, and nucleic acids. Ordinarily, catabolism discharges energy, and anabolism burns-through energy.
Unsaturated fat catabolism includes three phases. The principal phase of unsaturated fat catabolism is beta oxidation in the mitochondria. The subsequent stage is acetyl CoA oxidation to carbon dioxide. The third stage is electron move from electron transporters to the electron move chain. For an even numbered soaked fat (where the number of carbon is$2n$ ), $n - 1$ oxidations are vital for its total oxidation.
The complete ATP yield can be expressed as: $\left( {n{\text{ }} - {\text{ }}1} \right) \times 17 + 12 - 2$.
In this manner, here
$2n = 18$
$n = 9$
At that point the all out number of ATP yield is $9 \times 17 + 12 - 2 = 146$

Thus the option C is correct.

Note:
We have to know that the vast majority of the constructions that make up creatures, plants and organisms are produced using four fundamental classes of atom: amino acids, starches, nucleic corrosive and lipids (regularly called fats). As these particles are indispensable forever, metabolic responses either center around making these atoms during the development of cells and tissues, or by separating them and utilizing them as a wellspring of energy, by their absorption. This biochemical can be consolidated to make polymers like DNA and proteins, fundamental macromolecules of life.
