While some detractors emphasize the Marxian critique of capitalism, others contend that the Marxist economic system is untenable.

Marx thought that capitalism, which places a premium on profit and private property, results in societal inequality. In order to achieve this, he worked to create a system that would lead to a society without classes, in which everyone would benefit from the fruits of labor and the state would hold absolute power over all assets.

Capitalism was criticized by Marx as a system that alienates the general populace. He argued that although if people manufacture goods for the market, it is market forces that ultimately determine how things turn out.

An ionic bond involves a metal that transfers one or more electrons to a nonmetal.

Ionic bond, also called electrovalent bond, is a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence or the outermost electrons of one atom are transferred permanently to another atom.

Atoms form compounds so that they achieve stability. Compounds are formed when atoms form chemical bonds with other atoms. These bonds which can either be covalent or also be ionic due to the interactions of the valence electrons of the atoms.

Ionic bonds are formed when atoms transfer electrons from their valence shells to other atoms. This transfer is usually observed when metals transfer electrons to nonmetals. Since metals transfer electrons, they become cations. Nonmetals, on the other hand, form the anions.

for each molecule of glucose that is catabolized in glycolysis and the citric acid cycle, produced 10 NADH.

Each glucose molecule entering glycolysis produces two pyruvate molecules 2 ATP, and 2 NADH, thus doubling the number of pyruvate entering the citric acid cycle. The citric acid cycle cannot occur in the absence of oxygen, In the absence of oxygen, the pyruvate of converted to lactic acid which is broken down and excreted by the cell.

Pyruvate is a three-carbon molecular product of glycolysis. When oxygen is present in the cell, pyruvate is decarboxylated (C- is removed mediated by the pyruvate dehydrogenase complex) and two oxygen atoms are included to form carbon dioxide. A redox reaction also occurs when coenzyme A binds to form acetyl-CoA and NAD+ is reduced to NADH.

Each glucose molecule entering glycolysis produces two pyruvate molecules, thus doubling the number of pyruvate entering the citric acid cycle.

Therefore, the number of each ATP, NADH, and FADH2 molecule produced in the citric acid cycle is doubled. Therefore, in the citric acid cycle, one glucose molecule produces two ATPs, six NADHs, and two FADH2s.

Thus, 2 ATP, 6 NADH, and 2 FADH2 will be produced in the citric acid cycle by one glucose molecule

So, if the whole process of cellular respiration is summarized then the result is:

Glycolysis: 1 glucose → 2 pyruvic acid + 2 ATP + 2 NADH

Oxidative decarboxylation: 1 pyruvic acid → 1 acetyl-CoA + 1 NADH

Since 1 glucose produces 2 pyruvic acid, then from the oxidative decarboxylation stage:

2 pyruvic acid → 2 acetyl-CoA + 2 NADH

Krebs cycle: 1 acetyl CoA + 1 oxaloacetic acid → 1 citric acid + 3 NADH + 1 FADH2 + 1 ATP

Since 1 glucose produces 2 pyruvic acids and 2 pyruvic acids produce 2 acetyl-CoA, then from the Krebs cycle stage:

2 acetyl CoA + 2 oxaloacetic acid → 2 citric acid + 6 NADH + 2 FADH2 + 2 ATP

From the three stages of cellular respiration above, it can be concluded that one molecule of glucose can produce a total of 4 ATP, 10 NADH, and 2 FADH2.
