Answer:

One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.

Explanation:

  • Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
  • The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
  • A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
  • Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.

Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase comp
Morgarella [4.7K]

Answer:

The correct answer is option d.

Explanation:

The production of Acetyl-CoA takes place by the dissociation of both carbohydrates and lipids in the process of glycolysis and beta-oxidation. It then moves into the TCA cycle in the mitochondria and combines with oxaloacetate to give rise to citrate.  

In the given case, no labeling will be found in the acetyl-CoA. The labeled C3 and C4 carbon of glucose signify the carboxyl carbon of pyruvate. In the succeeding reactions of the transformation of pyruvate to acetyl-CoA, the carboxyl carbon gets lost in the form of carbon dioxide. Thus, acetyl-CoA does not comprise any labeled C3 and C4 of glucose.
