During strictly anaerobic exercise, muscle cells preferentially: a. carboxylate pyruvate to oxaloacetate. b. oxidize pyruvate to acetyl-CoA. c. decarboxylate pyruvate to acetaldehyde. d. reduce pyruvate to lactate. e. none of the above.

Option (B) is Right Answer

Explanation:

 (b) Oxidize pyruvate to acetyl-CoA.

The oxidative decarboxylation of Pyruvate to form Acetyl-CoA is the connection among Glycolysis and the Citric acid cycleIt is an irreversible oxidation process in which the carboxyl group is expelled from pyruvate as an atom of CO2 and the two residual carbons become the acetyl group of Acetyl-CoA Pyruvate can be changed over into sugars by means of gluconeogenesis, to unsaturated fats or energy through acetyl-CoA, to the amino acid alanine, and to ethanol

The basic building blocks of dna and rna are nucleotides

It explains why rocks appear in layers
