There may be more than one answer. Select any and all that apply. It is a linear 10 step pathway It generates ATP molecules directly through oxidative phosphorylation It produces two molecules of carbon dioxide It begins with acetyl coenzyme A and oxaloacetate combining It converts glucose to carbon dioxide It is a point of entry for the products of amino acid catabolism to be converted into energy It is an anaerobic process that produces molecules for an aerobic process that comes later The first step is the breakdown of glucose into glyceraldehyde-3-phosphate
