Which of the following conclusions can be drawn from this graph?
The optimum pH of the enzyme is 6.6.
The optimum pH of the enzyme is 5.8
The enzyme’s activity increases as pH increases 5.0 to 9.0
The enzyme’s activity is greater around pH of 8.0 .
What's going on in this picture?
The enzyme is taking the red substrate and turning it blue
The enzyme's active site is blocked by a competitive inhibitor
The enzyme can't function if too many substrates are trying to bind
This is an example of an anabolic enzyme reaction
With what 3 letters do enzymes typically end?
-ose
-ase
-ese
-tic
