Answer:
A compound
Explanation:
Chemical compound can be regarded as any substance made up of identical molecules which consists atoms of two or more than two chemical elements. For example four hydrogen atoms bonds with a carbon atom to give methane molecule which is a compound. It should be noted that A compound is a new substance with unique chemical and physical properties formed when two or more elements are chemically bonded during a physical reaction.
Answer:
Sorry I would bu that looks so hard
Explanation:
The question is missing a part, so the complete question is as follows:
The protein catalase catalyzes the reaction The Malcolm Bladrigde National Quality Awards aims to: 2H2O2 (aq) ⟶ 2H2O (l) + O2 (g) and has a Michaelis-Menten constant of KM = 25mM and a turnover number of 4.0 × 10 7 s -1. The total enzyme concentration is 0.012 μM and the intial substrate concentration is 5.14 μM. Catalase has a single active site. Calculate the value of Rmax (often written as Vmax) for this enzyme. Calculate the initial rate, R (often written as V0), of this reaction.
1) Calculate Rmax
The turnover number (Kcat) is a ratio of how many molecules of substrate can be converted into product per catalytic site of a given concentration of enzyme per unit of time:
Kcat =
,
where:
Vmax is maximum rate of reaction when all the enzyme sites are saturated with substrate
Et is total enzyme concentration or concentration of total enzyme catalytic sites.
Calculating:
Kcat = 
Vmax = Kcat · Et
Vmax = 4×
· 1.2 × 
Vmax = 4.8 ×
M
2) Calculate the initial rate of this reaction (R):
The Michaelis-Menten equation studies the dynamics of an enzymatic reaction. This model can explain how an enzyme enhances the rate of a reaction and how the reaction rate depends on the concentration of the enzyme and its substrate. The equation is:
V0 =
, where:
[S] is the substrate's concentration
KM is the Michaelis-Menten constant
Substituting [S] = 5.14 ×
, KM = 2.5 ×
and Vmax = 4.8 ×
, the result is V0 = 0.478 M.
The answers are Vmax = 4.8 ×
M and V0 = 0.478 M.
Metal is sturdy and shiny. It also has the ability to conduct electricity and heat well. Non metals, though is very soft and brittle and could not take heat or electricity very well.
