why nad+?
why nad+?
It could be glucose but i doubt it as many things can be hydrolysed to glucose.
What is the answer? I think you said in your OP you know.
Temperature could even become the limiting factor as enzymes are involved vague question.

Glycolysis is an anaerobic process so its not oxygen, you need to continue to reoxidise NAD so glycolysis can continue.

i know that glycolysis can happen aerobic and anaerobic.
and in glycolysis it converts NAD+ to NADH and ADP+Pi to ATP but why is limiting NAD+ going to inhibit production of ATP?

NAD+ is the answer. (because google told me) i wanted to know why it was the answer.

The ATP made during glycolysis is by substrate level phosphorylation.
This occurs specifically when a dehydrogenase enzyme dehydrogenates a molecules of glucose and NAD has to be reduced. (it accepts the Hydrogen)
If there is less NAD+ then less hydrogen acceptors so the rate of dehydrogenation of glucose and substrate level phosphorylation goes down. This decreases the rate of glycolysis as it means less dehydrogenation of glucose.

Limiting NAD+ availability prevents the entire process from happening and stops ATP from being produced. You can't produce ATP without first oxidising the substrate using NAD+.

without NAD+ ATP wlll not happen.

so NAD+ is first converted into NADH then ADP +Pi is converted into ATP which is why NAD+ is the limiting factor.
without NAD+ ATP wlll not happen.

They actually don't. =/

You sound like you know alot more
.Thats all I have been taught (doing A2s atm)
We don't have to talk about equilibrium at all either.

I would say that the supply of glucose, availability of NAD and availability of ADP would all be limiting factors
