<span>The correct answer is C. Bacteria are the only group of organisms that can fix nitrogen into the soil. This is incorrect because there are eukaryotes that can do that as well. They are however simpler organisms but they can nevertheless do it, meaning that bacteria are not the only ones. Such organisms can be the Archaea.</span>

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

2a) Which of the following statements about pyruvate oxidation IS TRUE?
Darina [25.2K]

The true statements are:

  • Substrate level phosphorylation ocvurs during Pyruvate oxidation
  • 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
  • Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
  • ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
  • ATP inhibits pyruvate dehydrogenase by feedback inhibition

<h3>What is glucose oxidation?</h3>

Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.

The first stage of glucose oxidation is the conversion to pyruvate.

Pyruvate is oxidized to acetylCoA.

AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.

  • The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
  • When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
  • In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
  • During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
  • Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.
