Glycolysis is the first step in cellular respiration. Which option best summarizes the process?

Question

A. aerobic; 6-carbon glucose forms four 3-carbon ADP; forms a net total of 3 ATP
B. anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP
C. anaerobic 6-carbon glucose forms two 3-carbon ADP; forms a net total of 4 ATP
D. anaerobic 6-carbon glucose forms tree 2 carbon pryuvates; forms a net total of 2 ATP

Answer 1

The option that best summarizes the process of glycolysis is:

B. anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP

Glycolysis occurs in the cytoplasm of the cell and does not require oxygen (anaerobic process). It involves the breakdown of a 6-carbon glucose molecule into two 3-carbon pyruvate molecules, and it produces a net gain of 2 ATP molecules.
