Which step in cellular respiration happens first?

Answers

The first step in cellular respiration is glycolysis. This is when the a 6 carbon glucose molecule is broken down into two molecules creating three carbon pyruvate.

Hope this helps. 🙂

Glycolysis

Glycolysis - breakdown of glucose molecule to 2 pyruvates which will go into next step/cycle (citric acid cycle aka Krebs cycle). I believe it is glycolysis that is the first step in cellular respiration. Complete oxidation of glucose via respiration = four step process used to convert chem energy in glucose to ATP.

Glycolysis: This is where one 6-carbon molecule of glucose is broken down into two molecules of the three-carbon pyruvate.

The answer is C, Glycolysis

Glycolysis. This is where one 6-carbon molecule of glucose is broken down into two molecules of the three-carbon
In regards to the basic steps, I believe your answer would be Glycolysis.
