Question
Molecule X (a 4 carbon molecule) reacts with a triphosphate to produce Molecule Y (an alkene) and carbon dioxide and a diphosphate. Molecule Y reacts with H2O to form Molecule Z, which is isomerized to Molecule W. Molecule W also reacts with Molecule A (ATP) to make Molecule Q, which has 2 phosphates.
(1) Each of the following is a reason that you would know that the above reactions are NOT part of the Kreb Cycle, except one. Which one?
a. Molecule Y has 3 carbons
b. Molecule Y has a phosphate
c. Diphosphate is a product
d. Carbon dioxide is produced
e. ATP is a reactant
(2) Each of the following is a reason that you might think that the above reactions are part of the Kreb Cycle, except one. Which one?
a. Atleast one intermediate has 4 carbons
b. An alkene is produced
c. An intermediate has 2 phosphates
d. Water is a reactant
e. An isomerization occurs
(3) These reactions must be part of:
a. Glycogen metabolism
b. Gluconeogenesis
c. Kreb cycle
d. Glycolysis
e. ETC
