Answer

Molecules / Glycolysis / Cellular Respiration -Glucose is split into two three-carbon pieces by glycolysis, which are further decomposed in the Kreb's cycle during cellular respiration. -Pyruvate is the end product of glycolysis and is decarboxylated to acetyl coA to be fed into cellular respiration. -Oxygen is not used in glycolysis but is the terminal electron acceptor for cellular respiration. -ATP is produced in glycolysis (overall, some used, more produced) and in cellular respiration. Glycolysis makes it by substrate-level phosphorylation and cellular respiration makes it using the ATP synthase. -Carbon dioxide is not produced by glycolysis, but (per glucose) one molecule of it is produced just after glycolysis in pyruvate oxidation and four more during cellular respiration.

Work Step by Step

This question is intended to help tie together several topics in your mind. To answer it, review the processes listed, making lists of where each molecule occurs. Then, produce a sentence for each chemical to connect glycolysis and cellular respiration using that molecule.
