Answer:
The turnover number is the maximum substrate quantitiy converted to product per enzyme and per second. It can be calculate as follows:
![k_c = \frac{V_{max}}{[E]}](https://tex.z-dn.net/?f=k_c%20%3D%20%5Cfrac%7BV_%7Bmax%7D%7D%7B%5BE%5D%7D)
with ![[E]](https://tex.z-dn.net/?f=%5BE%5D)
active enzyme concentration.
In this case we have Vmax an data to calculate
![[E]=\frac{3.38*10^{-14}}{0.01 L}=3.38*10^{-12} M](https://tex.z-dn.net/?f=%5BE%5D%3D%5Cfrac%7B3.38%2A10%5E%7B-14%7D%7D%7B0.01%20L%7D%3D3.38%2A10%5E%7B-12%7D%20M%20)
Now 
it is not like any option.
If we assume that 
have the non usual units of 
and it is 
So we need divide by the moles of E (in place of [E])
Now 
(pass from 
to 
dividing by 60)
It will form mountains, hope this helps
Answer: the correct option is that batteries (do NOT require a continuous source of fuel).
Explanation:
A battery can be classified as an electrochemical cell that has the ability to produce electric current. They do NOT require a continuous supply of fuel because it contains all the reactants needed to produce electricity. Below are some examples of batteries that are commonly used:
--> Primary battery: This is a single use battery because it can't be recharged. A typical example is the dry cell.
--> Secondary battery: This type of battery can be recharged. They are used as a power source for smartphones, electronic tablets, and automobiles.
A FUEL CELL is known as a device that converts chemical energy into electrical energy. Fuel cells are similar to batteries but require a continuous source of fuel, often hydrogen. They will continue to produce electricity as long as they are constantly resupplied with reactants. Hydrogen fuel cells have been used to supply power for satellites, space capsules, automobiles, boats, and submarines.
A pi bond is a bond formed by the overlap of orbitals in a side-by-side fashion with the electron density concentrated above and below the plane of the nuclei of the bonding atoms. ... Three sigma bonds are formed from each carbon atom for a total of six sigma bonds total in the molecule.
