During which stage of cellular respiration is glucose broken down into two molecules of pyruvic acid?
electron transport chain
glycolysis
krebs cycle
acetyl coa formation

B. Glycolysis

Explanation:

There's a "stage" between glycolysis and the citric acid cycle called aerobic respiration which includes pyruvic acid converting to acetyl-CoA This stage is considered part of glycolysis.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

archaebacteria are found in in forest soil.

hope i spelled it right lol

hope i
