Which substance is produced as a by-product of both glycolysis and aerobic respiration? a. nadh b. acetyl coa c. atp d. glucose

The correct answer is option C, that is, ATP.  

Glycolysis refers to the dissociation of sugar, generally the glucose into more convenient components in order to generate energy. The net end components of glycolysis are two NADH, two pyruvate, and two molecules of ATP.  

The cells going through the procedure of aerobic respiration generate six molecules of carbon dioxide, six molecules of water, and up to 30 molecules of ATP, which is directly used to generate energy, from each molecule of glucose in the existence of enough oxygen.  

Thus, the by-product of both the procedures is ATP.  

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
