Answer:
I took the test it's C.The volume will increase.
Explanation:
Since the pressure went down from 2 atm to 1 atm, the volume will go up! They are inversely related.
Answer:
27 min
Explanation:
By the Michaelis-Menten Kinetics Model, the initial velocity of the enzymatic reaction is given by:
where vmax is the maximum velocity, [S] is the substrate concentration and Km is the equilibrium constant. The maximum velocity is directly proportional to the enzyme concentration.
So, for 12μmol of the product formed in 9 min, the velocity is also:
v0 = 12/9 = 1.33 μmol/min
For [S] 1,000 times higher then Km, Km can be unconsidered in the equation, so:
v0 = vmax
vmax = 1.33 μmol/min
If the enzyme concentration decreases by three, the maximum velocity will also decrease by three, so it will be: 0.443μmol/min. Km continues the same, and [S] will be multiplied by 2, so Km can still be unconsidered. So:
v0 = vmax
v0 = 0.443 μmol/min
Then,
0.443 = 12/t
t = 12/0.443
t = 27 min
