Sodium benzoate is a bitter chemical often used in tiny amounts as a food preservative. The ability of humans to taste sodium be

If the dominant allele is t and the recessive allele ("non-taster") is n, than tn and tt are the  genotypes of a "taster". tn is heterozygous and tt is dominant homozygous. nn is the genotype of a "non-taster" and it is recessive homozygous.

Two different enzymes catalyze the same reaction and both exhibit the same Vmax. When Enzyme A was run with a 40 uM substrate, t
Vinil7 [7]

Answer:

a) k_m = 4.08 uM

  V_{max} = 20.07 uM/min

b) k_m = 8.16 uM

Explanation:

Given that:

For Enzyme A:

the substrate concentration [S] = 40 uM

the initial velocity rate v = 10 uM/min

when it was 4mM, v = 20 uM/min

i.e.

at 4mM = 4000 uM;

Using Michealis -menten equation;

when v = 10

V = \dfrac{V_{max}[S]}{k_m+[S]}

∴

10 = \dfrac{V_{max}\times 40}{k_m + 40}

10 (k_m + 40) = V_{max}40

40V_{max} -10k_m = 400 --- (1)

when v= 20

20= \dfrac{V_{max}\times 4000}{k_m + 4000}

20 (k_m + 4000) = V_{max}4000

4000V_{max} -20k_m = 8000 --- (2)

equating equation (1) and (2):

40V_{max} -10k_m = 400 --- (1)

4000V_{max} -20k_m = 8000 --- (2)

let multiply equation (1) by 100 and equation (2) by 1

4000V_{max} - 1000K_m = 4000

<u>4000V_{max} - 20 k_m = 8000     </u>

  0        -980k_m = 4000

k_m = 4000/-980

k_m = 4.08 uM

replacing the value of k_m into equation (1)

40{V_max } - 10(4.08) = 400

40{V_max } - 40.8 = 400

40{V_max } = 400 +  40.8

40{V_max } = 440.8

V_{max} = 440.8/40

V_{max} = 11.02 uM/min

b)

Since V_{max} of A ie equivalent to that of B; then:

V_{max} of B = 11.02 uM/min

Here;

[S] = 80  uM

V = 10 uM/min

∴

10 = \dfrac{11.02 \times 80}{k_m + 80 }

10(k_m +80) = 881.6

10k_m = 881.6  - 800

10k_m = 81.6

k_m = 81.6/10

k_m = 8.16 uM

Why is the cell wall responsible for the crispness of vegetables
Naddika [18.5K]
<span>The outermost covering of a plant cell is called cell wall. It is made up of cellulose. It surrounds the cell membrane. Its function is to protect the cell, provide mechanical support and maintain the pressure inside the cell. Fluid collects in the vacuole and pushes out against the cell wall. This turgid  pressure is responsible for the crispiness of fresh vegetables and flowers.</span><span />
