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

Theresa comes up with four examples of waves: Sound wave, Ocean wave, Light wave, and Hand wave. Which of Theresa’as examples is
In-s [12.5K]

Answer:

Hand wave

Explanation:

Transverse wave and longitudinal wave are two types of wave. Some of the examples of a wave are Sound wave, Ocean wave, Light wave etc. The disturbance in a medium is called wave.

Here, Theresa comes up with four examples of waves: Sound wave, Ocean wave, Light wave, and Hand wave. But hand wave is not an acutal scientic wave. It is just movement of hands. There is no transfer of energy takes place. Hence, hand wave is not an actual scientific wave.
