What are the two other molecules released during the Krebs cycle besides ATP?

Which of these is not a product of the citric acid cycle (also called the Krebs cycle)?

In the citric acid cycle, for each pyruvate that enters the cycle, one ATP, three NADH, and one FADH₂ are produced. For each glucose molecule that enters glycolysis, how many ATP, NADH, and FADH₂ are produced in the citric acid cycle?

Where in the cell does the Krebs cycle occur?

Where does the citric acid cycle occur in eukaryotes?

Which of these is not a product of the citric acid cycle?

Which of the following is not a product of the citric acid cycle?

What molecule is a product of the citric acid (Krebs) cycle?

Which of the following products is made in the citric acid cycle?

What waste product is generated during the Krebs Cycle?

What is a by-product of the Krebs cycle?

Why is the citric acid cycle called a "cycle"?

Which of the following correctly lists the main reactants and products of the Krebs Cycle?

How many molecules of NADH are generated for each turn of the Krebs Cycle?

In the citric acid cycle, an enzyme oxidizes malate to oxaloacetate, with the production of NADH and the release of H+. You are studying this reaction using a suspension of bean cell mitochondria and a blue dye that loses its color as it takes up H+. You set up reaction mixtures with mitochondria, dye, and three different concentrations of malate (0.1 mg/L, 0.2 mg/L, and 0.3 mg/L). Which of the following graphs represents the results you would expect, and why?
