When the rate of an enzymatic reaction cannot be increased by adding more substrate ______?

When the rate of an enzymatic reaction cannot be increased by adding more substrate ______?

جب مزید سبسٹریٹ ______ کو شامل کرکے انزیمیٹک رد عمل کی شرح میں اضافہ نہیں کیا جاسکتا ہے؟
Explanation

Saturation occurs when all active sites of the enzyme molecules are fully occupied by the substrate.

At this point, adding more substrate doesn't increase the reaction rate, as the enzyme is working at its maximum capacity (Vmax).
