Which trace mineral is important for activating a key enzyme in gluconeogenesis?

1 answer:

5 0

The correct answer is Manganese (Mn).
Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.

If someone with auburn hair has children with someone with red hair (but whose mother had black hair ) what are the genotype and

tensa zangetsu [6.8K]

The phenotype is - 75 % red and 25 %brown.

The genotype is hRhR - 25%

hBkhR - 50%

hBrhBk - 25%.

<h3>Explanation:</h3>

The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.

Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be

Father - hBr and hR

Mother - hBk and hR

So, the probable combinations are hBrhBk, hBrhR and hBkhR.

The frequency of the combinations are 25%, 25% and 50% respectively.

The phenotypic ratio will be red : brown as 3:1.

Color-blindness is a x-linked recessive disease. Under what circumstances will this condition manifest in a child? (2 points)

Lera25 [3.4K]

I think the correct answer from the choices listed above is the first option. The circumstances that this condition would manifest would be if the child is a male and its mother has the recessive allele. X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be expressed in males and in females who are homozygous for the gene mutation

A qualified genetics counselor is working with a child who has been diagnosed with fragile x syndrome. after extensive research

Alenkinab [10]

Answer:

CPT® Index - 96040

icd-10-cm code - Q99.2

Explanation:

Here in this case the diagnosis came out with fragility in X chromosome. This is some thing related with medical genetics. Hence, the CPT® Index for this scenario would be 96040. As per the American Medical Association, CPT® Index 96040 cover cases that fall into the category of “Medical Genetics and Genetic Counseling Services” which also involves counseling either with the patient or family for 30 minutes. The icd-10-cm code – Q99.2 deals with the problems associated with genetic abnormality

Hence, the answer is

CPT® Index - 96040

icd-10-cm code - Q99.2
