Answer:
b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.
Explanation:
Hello,
In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.
Best regards.

Answer is: when the carbon atoms of the glucose molecule are broken apart in glycolysis and the Krebs cycle, result is a. CO2 and ATP.
In Krebs cycle aerobic organisms release stored energy through the oxidation of acetyl-CoA derived from glucose into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).
