Question

experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domains, Archaea, bacteria, an eukarya. Which of the following hypotheses could be best supported by this evidence

Answer 1

The question is incomplete as it lacks the multiple options. The multiple options are as follows:

a. Across the three domains, all organisms depend solely on the process of anaerobic respiration for ATP production .

b. Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life .

c. The existence of glycolysis as an energy-releasing process in all organisms suggests that convergent evolution occurred .

d. All organisms carry out glycolysis in mitochondria.

Answer:

Option (b).

Explanation:

The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more closely related with each other than the prokarya.

The glycolysis is the process of breakdown of glucose molecule to generate ATP. The glycolysis is the most common process of the generation of the ATP are present in almost all the organisms whether the organisms is ancestral or modern.  

Thus, the correct answer is option (b).
