Answer:

In Diels alder reaction

It's an Adduct that is fromed from the reactants

Explanation:

I.e diene + dienophile= Adduct

E.g 1,3-butadiene + ethene = cyclohexene

Express your answer using two significant figures.<br><br><br> 2.7 cm3 = m3<br><br> 2.0 mm3= m3
natka813 [3]

Answer:

2.7 cm³ = 2.7 x 10⁻⁶ m³

2.0 mm³ = 2.0 x 10⁻⁹ m³

Explanation:

The values are multiplied by the conversion ratio, being sure to raise the ratio to the power of 3 so that the units properly cancel:

(2.7 cm³)(1m/100cm)³ = 2.7 x 10⁻⁶ m³

(2.0 mm³)(1m/1000mm)³ = 2.0 x 10⁻⁹ m³

Given that the concentration of myosin is 25pmol·L−1 and Rmax(Vmax)=208pmol·L−1·s−1 , determine the turnover number of the enzym
DedPeter [7]

Answer:

8.32 s⁻¹

Explanation:

Given that:

The concentration of myosin = 25 pmol/L

R_max = 208 pmol/L/s

The objective is to determine the  turnover number of the enzyme molecule myosin, which has a single active site.

In a single active site of enzyme is known to be a region where there is binding of between substrate molecules, thereafter undergoing chemical reaction.

The turnover number of the enzyme is said to be the number of these substrate molecule which binds together are being converted into products.

The turnover number of the enzyme molecule of myosin can be calculated by the expression: \dfrac{R_{max}}{concentration}

⇒ \dfrac{208 pmol/L/s}{25 pmol/L}

= 8.32 s⁻¹

Which of the following you do NOT need to pay attention while using a centrifuge?
Phoenix [80]

Answer:

The radius of the centrifuge.

Explanation:

Hello,

Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.

Best regards.
