An understanding of anatomy is key to the practice of health and medicine
Answer:
In the dominant- recessive model of inheritance, the dominant allele fully suppresses the recessive allele. As a result, heterozygous individuals produced show the effect of the dominant trait in them. For the recessive trait to occur, both the alleles of the gene should be recessive in the organism.
In co- dominance model of inheritance, the dominant allele is not fully dominant over the recessive trait. As a result, heterozygous individuals show both the dominant and recessive characteristic in them. For a dominant trait to occur, both the alleles should be dominant. For a recessive trait to occur, both the alleles should be recessive.

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
∴
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
