Question

What glycolysis product is transported into the mitochondria?

Answer 1

Two Pyruvate, two NADH, and two ATP molecules are the products of the glycolysis which are sent to the mitochondria of the cell.

Step-by-step explanation:

Glycolysis is a first step of cellular respiration in which glucose molecule is broken down and producing pyruvate, NADH and ATP molecules. These three products are sent to the mitochondria of the cell for further energy production for the cell. Mitochondria is also called power house of the cell where energy is produced in the form of adenine tri phosphate with the addition of oxygen which comes from the process of breathing.

Answer 2

This question lacks options, options are:

A) ATP

B) NADP

C) Pryuvate

D) glucose

E) acetyl-CoA.

The correct answer is C) Pyruvate.

Step-by-step explanation:

Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
