The blood concentration of glucose in a normal healthy individual is:

1. 3.5 – 4.0 mM	2. 4.0 – 4.5 mM
3. 4.2 – 6.1 mM	4. 5.0 – 5.5 mM

All the following assumptions apply to Michaelis-Menten kinetic analyses of enzyme action EXCEPT:
1. the total enzyme concentration studied at each substrate concentration is fixed in analysis of enzyme kinetics.
2. formation of enzyme-substrate complex does not appreciably decrease the concentration of substrate.
3. Km decreases with competitive inhibition.
4. maximal velocity is reached when the enzyme-substrate complex is equal to the total concentration of enzyme present.
