For a given acid HA, it was determined that at pH 6.0 the concentration of the conjugate base [A]
was 0.075 M and the acid [HA] was 0.025 M.
What percent of this acid is ionized at pH 6.0?
What is the pKa of this acid?
What pH would this acid be 50% lonized?
To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs. These drugs can each pick up electrons from specific intermediates in the pathway as shown above.
You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table.
In the presence of drug A, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.
In the presence of drug B, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.
All are true of the Embden-Myerhof pathway EXCEPT
Question 88 options:
A)
the products pyruvic acid and ATP under aerobic conditions enter the Krebb's (TCA) cycle to produce more ATP
B)
the products pyruvic acid and ATP under anaerobic conditions are converted to lactic acid and two additional ATP
C)
Cells use this pathway when they have no energy needs
D)
Begins with the conversion of glucose into glucose-6-phosphate
