Answer:

17.2 minutes is the value of the turnover number.

Explanation:

Using Michaelis-Menten equation:

V = V_{max}\times \frac{[S]}{ (Km + [S])}

V_{max }=k_{cat}\times E_o

Where  :

V_{max} = max rate velocity

[S] = substrate concentration

K_m = Michaelis-Menten constant

V = reaction rate

k_{cat} = catalytic rate constant

E_o = initial enzyme concentration

We have :

K_m=10.0mM

E_o=10.0\mu M=10.0\times 0.001 mM

V_{max}=0.172 mM/min

V_{max} is the rate is obtained when all enzyme is bonded to the substrate. k_{cat} is termed as the turnover number.

k_{cat}=\frac{V_{max}}{E_o}=\frac{0.172 mM}{10.0\times 0.001 mM}

=17.2 minutes

17.2 minutes is the value of the turnover number.

Which one of the following statements about mixtures is correct [2] [3] The different substances in a mixture are always in a de
aivan3 [116]

Answer: Option (4) is the correct answer.

Explanation:

A mixture is defined as a substance that contains two or more different substance that are physically mixed with each other.

If solute particles are evenly distributed in a solvent then it is known as a homogeneous mixture.

For example, salt dissolved in water is a homogeneous mixture.

If solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.

For example, sand in water is a heterogeneous mixture.

Thus, we can conclude that the statement a mixture must contain at least two different substances, is correct about mixtures.

MrRa [10]

During the riding of the steep mountain, the body needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.

<h3>What is the effect of cycling?</h3>

Cycling is a good exercise as swimming, while cycling, happy hormones are released like dopamine and serotonin.

The primary forces that work while cycling are gravity, friction, rolling resistance, and air resistance.

Thus, During the riding of the steep mountain, the bod needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.
