Glycolysis

Post by hkt1030 » Fri Feb 19, 2010 4:00 am

In the first step of glycolysis, the enzyme hexokinase uses ATP to transfer a phosphate to glucose to form glucose-6-phosphate. Suppose that a cell has only glucose available for energy and that the activity of hexokinase is suddenly and completely inhibited in this cell. In terms of ATP production, [u]what will happen immediately? What will happen over time?[/u]

I guess you're talking about human, so immediately all metabolism will stop, after some time, Glc level should increase and glucose kinase will work in liver.

Cis or trans? That's what matters.

i think something else can happen
like
a cell will transport more atp in
and if we consider its inhibition, then it depends on how much time it takes for the inhibition and to what extent does it take place.
if its a complete inhibition and you consider the moment after that glycolysis should stop unless another enzyme replaces it or does its function.
it isn't what you do that matters but it is how you do it
