Answer:5
μM is the initial concentration of the substrate, [S], used in the reaction.
Explanation:
Michaelis–Menten 's equation:
![v=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}](https://tex.z-dn.net/?f=v%3DV_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%28K_m%2B%5BS%5D%29%7D%3Dk_%7Bcat%7D%5BE_o%5D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%28K_m%2B%5BS%5D%29%7D)
![V_{max}=k_{cat}[E_o]](https://tex.z-dn.net/?f=V_%7Bmax%7D%3Dk_%7Bcat%7D%5BE_o%5D)
v = rate of formation of products =
μM/s
[S] = Concatenation of substrate = ?
![[K_m]](https://tex.z-dn.net/?f=%5BK_m%5D)
= Michaelis constant = 15.0 μM
= Maximum rate achieved
= Catalytic rate of the system = 221 
![[E_o]](https://tex.z-dn.net/?f=%5BE_o%5D)
= Initial concentration of enzyme. =0.0100 μM
On substituting all the given values:
![[S]=7.26\times 10^{-6}](https://tex.z-dn.net/?f=%5BS%5D%3D7.26%5Ctimes%2010%5E%7B-6%7D)
μM
μM is the initial concentration of the substrate, [S], used in the reaction.
Answer: bacteria, archaea, plants, protists, animals, and fungi
Explanation: Throughout the history of evolution, cellular respiration has been a central element of many organisms' functioning. Even as species have developed and changed through the process of natural selection, all of the successful, surviving individuals have kept the genes that allow them to produce the enzymes needed for cellular respiration.
It should probably be chemical
