For an enzyme that displays Michaelis-Menten kinetics, what is the reaction velocity, v(as a percentage of Vmax), observed at:a)

fiasKO [112]

Answer:

a) 50% of the maximum velocity

b) 33.33% of the maximum velocity

c) 9.09% of the maximum velocity

d) 66.66% of the maximum velocity

e) 90.9% of the maximum velocity

Explanation:

The Michaelis-Menten kinetis is represented by

v = Vmax*S/(Km+S)

where

v= reaction rate

S= Substrate's concentration

Vmax= maximum rate of reaction

Km= constant

a) for S=Km

v = Vmax*Km/(2Km) = Vmax/2

v/Vmax = 1/2= 50% of the maximum velocity

b) for S=Km/2

v = Vmax*(Km/2)/(3/2Km) = Vmax/3

v/Vmax = 1/3= 33.33% of the maximum velocity

c) for S= 0.1*Km=Km/10

v = Vmax*(Km/10)/(11/10Km) = Vmax/11

v/Vmax = 1/11= 9.09% of the maximum velocity

d) for S=2*Km

v = Vmax*(2*Km)/(3*Km) = (2/3)* Vmax

v/Vmax = 2/3 = 66.66% of the maximum velocity

d) for S=10*Km

v = Vmax*(10*Km)/(11*Km) = (10/11)* Vmax

v/Vmax = 10/11 = 90.9 % of the maximum velocity

How can i make babies

Studentka2010 [4]

Answer with Explanation:

Babies are formed when the sperm cell from the male testicular gonad meets with the women's egg cell (from the ovaries). This penetration causes the "fertilization process." This naturally occurs two weeks from the woman's last day of menstruation. The fertilization allows the egg to rapidly divide. This is followed by "implantation," a process whereby the blastocyte attaches to the woman's endometrium. Around three weeks, the blastocyte is formed into an embryo. This will be called fetus once the woman reaches its 8th week of pregnancy.

This is a brief process regarding your question on how babies are formed.

Explain why (CH3)2CHCH(Br)CH2CH3 reacts faster than (CH3)2CHCH2CH(Br)CH3 in an E2 reaction, even though both alkyl halides are 2

NikAS [45]

Answer:

The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure.

The second structure has more hydrogens attached to the β carbons than the first structure.

Explanation:

It is possible to explain the reaction based on Zaitsev’s rule that states that an elimination will normally lead to the most stable alkene as the major product. This normally translates to it giving the most substituted alkene.

The two adjacent carbons in the first molecule are secondary. That means the two products will produce a disubstituted alkene but in the second molecule just one product will be disubstituted. Thus:

The first structure has more hydrogens attached to the β carbons than the second structure. FALSE. If the structure has more hydrogens will produce an alkene less stable.

The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure. TRUE. As the first structure have more alkyl groups the product is most stable.

The major and minor products formed from the second structure have more alkyl groups on the C═C than those formed from the first structure. FALSE. Is the opposite of the last option.

The second structure has more hydrogens attached to the β carbons than the first structure. TRUE. As the second structure has more hydrogens, the alkenes produced will be less substituted being less stable.

I hope it helps!

A sample of C3H8 has 6.96 × 1024 H atoms. How many carbon atoms does the sample contain?

Anastaziya [24]

A sample has 3.28 X 10^24 h atoms

so first we will find the moles of Hydrogen by putting values in formula
that is
. moles = no. of atoms/ Avogadro's no (NA) moles
= 5.446 we got this
 now the ratio of Carbon and Hydrogen is: C = H 
 3 = 8 
now multiply it with the moles
3/8 * 5.466 = 5.466 2.05 is the moles of C
. now:find the no of C atoms by this
 = moles X NA 
= 2.05 X 6.022 X 10^23
= 1.27 X10^2
now will find the mass of sampl:
so One mole of C3H8 = 3 moles of C 1/3 * 2.05 = 2.05 moles of C
 0.68 moles of C3H8. 
now the mass of C3H8 = moles X molar mass mass of C3H8
which is = 0.68 X 44 =
 30.2 grams of C3H8
