Question
The following is incorrect regarding the statement “A small amount of ATP is made in glycolysis”:
a) The process takes place through substrate-level phosphorylation.
b) Enzymes producing ATP from ADP + Pi, coupled with DG < 0 reactions, are called kinases.
c) A total investment of 2 ATPs renders a total of 4 ATPs with a net gain of 2 ATPs.
d) Substrate-level phosphorylation depends on a DpH and a voltage gradient.
e) ATP is formed by phosphoglycerate kinase and pyruvate kinase.
------
Which of the following is not true of glycolysis?
a) it splits glucose to form two molecules of pyruvate
b) it begins the oxidation of glucose
c) it produces a small amount of ATP
d) it generates NADH + H+
e) it oxidizes glucose to carbon dioxide
-----
Where does oxidative phosphorylation take place in the animal cell and what other processes are required for this to occur?
a) It takes place in the mitochondrion and follows the production of NADH + H+ and FADH2.
b) It takes place in the mitochondrion and immediately follows glycolysis.
c) It takes place in the smooth endoplasmic reticulum and requires lipid biosynthesis.
d) None of the above.
-------
In the generation of ATP by oxidative phosphorylation inorganic phosphate (Pi) binds directly to ADP via a
dehydration reaction (i.e., ADP + Pi ? ATP).
a) True b) False
-------
Anaerobically growing yeast further metabolizes the pyruvate produced by glycolysis to CO2 and ethanol as part of a series of fermentation reactions. A physiological role of fermentation, other than the production of small amounts of ATP, is to regenerate NAD+.
a) True b) False?
Explanation / Answer
Q1
A small amount of ATP is made in glycolysis
The correct answer is option (d).
This statement is incorrect because
Substrate-level phosphorylation does not depend on a DpH and a voltage gradient.
Glycolysis is a stepwise sequence of formation and breakage of products to get pyruvate.
Q2
Which of the following is not true of glycolysis?
The correct answer is option (e).
e) it oxidizes glucose to carbon dioxide.
Q3
The correct answer is option A
a) It takes place in the mitochondrion and follows the production of NADH + H+ and FADH2.
Q4)
FALSE
Q5)
TRUE
