Answer:
The
of a substrate will be "10 μM".
Explanation:
The given values are:
![E_{t} = 20 \ nM](https://tex.z-dn.net/?f=E_%7Bt%7D%20%3D%2020%20%5C%20nM)
![[Substract] = 40 \ \mu M](https://tex.z-dn.net/?f=%5BSubstract%5D%20%3D%2040%20%5C%20%5Cmu%20M)
![K_{cat}=600 \ s^{-1}](https://tex.z-dn.net/?f=K_%7Bcat%7D%3D600%20%5C%20s%5E%7B-1%7D)
Reaction velocity, ![Vo=9.6 \ \mu M s^{-1}](https://tex.z-dn.net/?f=Vo%3D9.6%20%5C%20%5Cmu%20M%20s%5E%7B-1%7D)
As we know,
⇒ ![Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}](https://tex.z-dn.net/?f=Vo%3D%5Cfrac%7BK_%7Bcat%7D%5BE_%7Bt%7D%5D%5BS%5D%7D%7BK_%7Bm%7D%2B%5BS%5D%7D)
On putting the estimated values, we get
⇒ ![9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}](https://tex.z-dn.net/?f=9.6%3D%5Cfrac%7B600%5Ctimes%2020%5Ctimes%2010%5E%7B-3%7D%5Ctimes%2040%7D%7BK_%7Bm%7D%2B40%7D)
⇒ ![K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}](https://tex.z-dn.net/?f=K_%7Bm%7D%2B40%3D%5Cfrac%7B600%5Ctimes%2020%5Ctimes%2010%5E%7B-3%7D%5Ctimes%2040%7D%7B9.6%7D)
⇒ ![K_{m}+40=50](https://tex.z-dn.net/?f=K_%7Bm%7D%2B40%3D50)
On subtracting "40" from both sides, we get
⇒ ![K_{m}+40-40=50-40](https://tex.z-dn.net/?f=K_%7Bm%7D%2B40-40%3D50-40)
⇒ ![K_{m}=10 \ \mu M](https://tex.z-dn.net/?f=K_%7Bm%7D%3D10%20%5C%20%5Cmu%20M)
Answer:
C. A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through
Explanation:
A circuit that are made of one loop is called series circuit. On the other hand, the parallel circuit has at least two loops. The circuit type has nothing to do with open or closed circuit.
If any part of the series circuit got cut, the current will stop flowing since there is only one loop. A parallel circuit has more loop so the circuit might still work even if a part of the circuit got cut.
The air pressure. the air pressure increases as the altitude an object is at increases.
