What are the reactants of the Krebs cycle in cellular respiration?

Krebs Cycle Reactants The only reactants of the Krebs cycle proper are acetyl CoA and the aforementioned four-carbon molecule, oxaloacetate. The availability of acetyl CoA hinges on adequate amounts of oxygen being present to suit the needs of a given cell.Click to see full answer. Besides, what goes in and comes out of Krebs cycle? Steps of the Krebs Cycle After citric acid forms, it goes through a series of reactions that release energy. The energy is captured in molecules of NADH, ATP, and FADH2, another energy-carrying compound. Carbon dioxide is also released as a waste product of these reactions.Subsequently, question is, what are the reactants of cellular respiration? Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water. Subsequently, question is, where do the reactants for the Krebs cycle come from? Explanation: Citric acid cycle inputs are derived from glycolysis outputs. Glycolysis produces pyruvate molecules, , and ATP. The pyruvate molecules undergo reactions that convert the three carbon pyruvate to a two carbon acetyl CoA and an one carbon carbon dioxide.How many ATP are used in the electron transport chain? 32
