Below are the products of one pyruvate going through the krebs cycle. which one is not correct? a. 3 co2 molecules b. 3 atp molecules c. 4 nadh molecules d. 1 fadh2 molecule

The correct answer is b. 3 ATP molecules.

During glycolysis, glucose (6 carbon) is broken down to Pyruvate (3 carbon). This the first phase of cellular respiration occurs in cytoplasm of a living cell. Further breakdown of pyruvate takes place in the matrix of a mitochondria.  Before the start of the Krebs cycle, pyruvate produced in the cytoplasm is converted into acetyl coenzyme A (acetyl CoA). Acetyl CoA is enters into Krebs cycle. One pyruvate yields 3 CO₂ molecules 1 ATP molecule, 4 NADH molecules and 1 FADH₂ molecule through Krebs cycle. It does not produce 3 ATP molecules.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
