Answer:
17.2 minutes is the value of the turnover number.
Explanation:
Using Michaelis-Menten equation:
![V = V_{max}\times \frac{[S]}{ (Km + [S])}](https://tex.z-dn.net/?f=V%20%3D%20V_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%20%28Km%20%2B%20%5BS%5D%29%7D)
Where :
= max rate velocity
[S] = substrate concentration
= Michaelis-Menten constant
V = reaction rate
= catalytic rate constant
= initial enzyme concentration
We have :
is the rate is obtained when all enzyme is bonded to the substrate. is termed as the turnover number.
17.2 minutes is the value of the turnover number.
Ooo that cool good thing I learn from this app
Answer:
Strontium, a group 2 element with an electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² , will form a +2 ion in a chemical bond.
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
So an ion is an atom or group of atoms that have an electric charge. A cation is an ion that has a positive charge.
The alkali metals in the earth (Elements IIA) lose two electrons to form a 2+ cation. Strontium is an alkali metal that loses the two electrons belonging to 5s², forming the +2 ion.
Answer:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding
