activates phosphofructokinase

activates fructose-1,6-bisphosphatase

both (b) and (c)

TRUE ANSWER : ?
YOUR ANSWER : ?

All of these

Pyruvate kinase

TRUE ANSWER : ?
YOUR ANSWER : ?

The enzymes of glycolysis in a eukaryotic cell are located in the

plasma membrane

mitochondrial matrix

cytosol

intermembrane space

TRUE ANSWER : ?
YOUR ANSWER : ?

ATP is from which general category of molecules?

Polysaccharides

Nucleotides

Proteins

Amino acids

TRUE ANSWER : ?
YOUR ANSWER : ?

In glycolysis, ATP is formed by the transfer of a high-energy phosphate from 1,3-bisphosphoglycerate to ADR No such high-energy phosphate donor has ever been isolated in mitochondria because

the high-energy phosphate donor is very short-lived and difficult to isolate

no such phosphate donor exists

None of these

the techniques for isolating the phosphate donor are not refined enough

the gibbs free energy will be positive

both (b) and (c)

more products will be formed
