Question

The advantage of the pentose phosphate pathway is that it produces all of the following except:
a. three ATPs
b. precursors for the synthesis of amino acids
c. precursors for the synthesis of glucose
d. NADPH
e. precursors for nucleic acids

Answer 1

Answer:

The correct answer is a. three ATPs

Explanation:

Pentose phosphate is also known as hexose monophosphate shunt and this pathway is the alternative pathway through which glucose is oxidized.  

Pentose phosphate pathways are used to produce many intermediated that contains 4 and 5 carbon sugars which are then used as the precursor for synthesis of amino acids and nucleic acids.  It also provides precursors for the synthesis of glucose.

NADPH is also produced in this pathway which is used for the reduction of molecules by providing a source of electrons. No ATP generation takes place during the pentose phosphate pathway.

So all the statements are true except a. three ATPs.
