In the interview with CHLOE ESTEROL, O2 says that if glucose can't enter The Cell, then cellular respiration would be affected.

mrs_skeptik [129]

Answer:

I and V

Explanation:

All living organisms undergo the process of CELLULAR RESPIRATION, which is the metabolic process of breaking down glucose in order to release the stored energy in its bonds and convert them in usable form by the cell (ATP). Cellular respiration can be aerobic (presence of oxygen) or anaerobic (without oxygen). This process involves Glycolysis which is an initial step undergone by all organisms because it does not require oxygen. Glycolysis occurs in the cytoplasm of living cells in both prokaryotes and eukaryotes.

Aerobic cellular respiration further contains Kreb cycle and Oxidative phosphorylation which occurs in the mitochondria of eukaryotic cells. In a nutshell, glucose is broken down to produce ATP which the organism uses to power its life processes. water and Carbondioxide (CO2) are also released as byproducts.

The General equation for aerobic cellular respiration is as follows:

C6H12O6 + 6O2----> 6CO2 + 6H2O + ATP

the couple is also concerned about their child inheriting hemophilia, another rare disease, which is x-linked. natalie’s brother

IgorC [24]

Hemophilia is a recessive X-linked condition and is inherited from parents. . The probability that Natalie and Daniel’s first child has hemophilia is 1/4, not 1/8. The statement is false.

<h3>What is an X-linked gene?</h3>

When talking about sex-linked genes, we refer to all those genes located in one of the sex-chromosomes and not in the somatic ones.

X-linked genes are the genes located specifically in the X sex chromosome.

Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.

According to this, X-linked genetic disorders will be inherited as well.

Men have a high probability of being affected since they only have one copy of the X chromosome.

In women, the effect of the mutation might be musk in heterozygous state if the mutation is recessive.

Hemophilia is a recessive X-linked disorder, which means it is coded by the recessive allele.

X+ ⇒ X chrosomosome with Dominant allele

X- ⇒ X chrosomosome with Recessive allele

Genotype Phenotype

X+X+ Healthy woman

X+X- Healthy carrier woman

X-X- Hemophilic woman

X+Y Healthy man

X-Y Hemophilic man

Let us make a pedigree of these families,

Natalie's family:

Mother healthy carrier X+X-

Father healthy X+Y

Brother hemophilic X-Y

Natalie Healthy X+X- or X+X+

Natalie has 1/2 chances of being carrier X+X- and 1/2 of being X+X+.

Daniel's family:

Mother healthy carrier X+X-

Father hemophilic X-Y

Sister hemophilic X-X-

Daniel Healthy X+Y

He has 1/2 chances of being healthy X+Y and 1/2 of being affected X-Y.

According to the product probability rule, if events A and B are independent from each other, the probability of occurrence of both events together is

P(A∩B) = P(A) x P(B)

In this case,
