biochemistry question-finding substrate concentration?
 
Km is 15 microM. what is the substrate concentration when Vo=2.3microM/min?

The answer is 1.2microM, but how?

Km=[S], when Vo=1/2Vmax

I used formula Vo=Vmax [S]/Km, but cannot get the correct answer.

Thank you very much for your help!

Hello,

You have not supplied enough information, I recon. You need a value for vmax, or information allowing you to calculate it.

Can you provide a more complete description of the problem?
