Glycolysis must occur before any of the other steps.

Explanation:

Glycolysis is the initial step in breaking down the 6-carbon sugar like glucose into 3-carbon organic molecules and finally results into the production of the two molecules of the 3-carbon compounds which is called "pyruvate". Pyruvate is converted into acetyl coenzyme A during pyruvate processing and enters into citric acid cycle or krebs cycle and the reduced compounds like NADH and FADH2 will be oxidized to transport electrons and protons in order to generate the ATP molecules.

Why are viruses referred to as obligate fuasites?

Elena L [17]

Answer:

b. They cannot reproduce outside of a host cell.

Explanation:

Viruses are parasitic organisms that need a host in order to thrive and reproduce. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means being restricted to a specific mode or function in life. This shows that the virus has a restriction when it comes to reproduction. It cannot reproduce without finding a host cell.
