Ok here I go The answer is A
Answer:
The lytic cycle results in Immediate death of host cell.
Explanation:
- Lytic cycle is followed by virulent phages.
- Lysogenic cycle as well as lytic cycle are followed by temperate phages.
- During lytic cycle the host cell is lysed and new viruses are released very quickly .
- During lysogenig cycle, the viral genome integrates into the host genome and creates a prophage. When the infected cell replicates the prophage also replicates. Later at some time the prophage enter the lytic cycle.
- The main difference between the lytic and lysogenic cycle is, lytic cycle involves the lysis of the host cell while lysogenic cycle does not involve lysis of host cell.
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]}](https://tex.z-dn.net/?f=V%20%3D%20%5Cdfrac%7BV_%7Bmax%7D%5BS%5D%7D%7Bk_m%2B%5BS%5D%7D)
∴



when v= 20



equating equation (1) and (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(k_m +80) = 881.6
10k_m = 881.6 - 800
10k_m = 81.6
k_m = 81.6/10
k_m = 8.16 uM
