what coenzyme takes hydrogen ions to the electron transport chain?

• ATP

• NAD

• ADP

• Electrons

during the citric acid cycle, what does citrate get turned back into after a series of enzyme controlled reactions?

• lactate

• carbon dioxide and ethanol

• ATP

• oxaloacetate

what is the induced fit?

• the active site changes shape to better fit the substrate after the substrate binds

• the enzyme has a lower affinity for the substrate

• a competitive inhibitor is competing for the active site

• the substrate changes shape to better fit the enzyme

ATP is broken down into ADP and a phosphate. This is an example of...
