If the concentration of enzyme is kept constant and amount of substrate is increased a point is reached where increase in substrates concentration does not affect the reaction rate because of

A. Enzymes get denatured at higher substrate conc
B. Rate of reaction is indirectly proportional to substrate concentration at this point
C. All the active sites on enzyme molecule are occupied
D. None of these

The rate of reaction is directly proportional to the concentration of an enzyme which statement is incorrect in this respect?

A. Increase in enzyme molecule increases the available active sites.
B. This relation is for unlimited time period with unlimited enzyme concentration
C. If the concentration is doubled the rate will become two fold.
D. None of these

If more substrate to already occurring enzymatic reaction is added more enzyme activity is seen because

A. There is probably more substrate present than there is enzyme.
B. There is probably more enzayme available than there is substrate.
C. There is probably more product present than there is either substrate or enzyme.
D. The enzyme substrate complex is probably failing to form during the reaction
