Which product does the krebs cycle require from the electron transport chain? atp coa nad+ nadh pyruvate

The correct answer is option A and C,  i.e ATP and NAD+

Explanation:

The kerb cycle produces two molecules of ATP for each glucose molecule going through the process of glycolysis. In the glycolysis process two acetyl coenzyme A molecules are produced. Oxaloacetic acid, a four-carbon molecule, combines with acetyl coenzyme A thereby donating acetyl group to Oxaloacetic acid and forming Citric acid. Citric  acid is further oxidized by the electron carrier NAD+ which reduces to form NADH+ and H+

explanation:

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
