Question

In the first step of cellular respiration, also known as glycolysis, a six carbon _________ molecule is converted into _________.
a. glucose ; pyruvic acid
b. glucose ; ATP
c. ATP ; glucose
d. pyruvic acid ; glucose

Answer 1

The first step of cellular respiration is glycolysis, where a six carbon glucose is broken down into a three carbon, this is called pyruvic acid. You're welcome

If you want the other steps in cellular respiration or cytology, just ask, I'm an A+.

Answer 2

Correct answer: A). Glucose ; pyruvic acid  

Glycolysis is the metabolic pathway that is known to convert glucose into pyruvate. The end product that is obtained after glycolysis is called as pyruvate, it can be further used in either anaerobic respiration or aerobic respiration. At the end of glycolysis, one glucose mole is broken into two molecules of pyruvate, ATP.

Hence, the correct answer would be option A.
