Glycolysis
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

None of these
the high-energy phosphate donor is very short-lived and difficult to isolate
no such phosphate donor exists
the techniques for isolating the phosphate donor are not refined enough

Glycolysis
Which of the following is not true of glycolysis?

The pathway does not require oxygen
The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters
The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose
ADP is phosphorylated to ATP via substrate level phosphorylation

Glycolysis
Why does the glycolytic pathway continue in the direction of glucose catabolism?

High levels of ATP keep the pathway going in a forward direction
The enzymes of glycolysis only function in one direction
There are essentially three irreversible reactions that act as the driving force for the pathway
Glycolysis occurs in either direction
