Answer: 1/16, or approximately 6.25% (see explanation below)
Explanation:
Answering this question requires two steps.
First, we need to figure out the probability that this couple will have a child with albinism in the first place. We know the following:
- Both parents are unaffected.
- The couple has already had one affected child.
- Albinism follows an autosomal recessive inheritance pattern.
Let ( M = normal gene ) and ( m = mutated gene ). Since the condition is recessive, the affected child can be assumed to have a “mm” genotype. Barring the possibility of a de novo mutation (which are assumed to be rare), the affected child must have inherited one ”m” allele from each parent. Since both of them are unaffected, however, we can assume that they are both carriers (genotype “Mm”). In conclusion, 1/4 of their offspring (25%) <em>for any given pregnancy</em> may be expected to have albinism. See the resulting Punnett square:
<u> | M | m </u>
<u>M | MM | Mm </u>
<u>m | Mm | mm </u>
Note that the question asks about the probability that not one but two consecutive births result in affected children. Since it can be assumed that both events are independent (meaning: the outcome of a pregnancy does not influence the outcome of following ones), we may apply the rule of multiplication for probabilities. The final answer is therefore 1/4 * 1/4 = 1/16.
Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two molecules. This is because glycolysis is at first endergonic.
<h3>
What is glycolysis?</h3>
- The metabolic process that turns glucose into pyruvic acid is known as glycolysis.
- The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process.
- A series of ten enzyme-catalyzed processes make up glycolysis.
- The process by which glucose is broken down to provide energy is known as glycolysis.
- It generates two pyruvate molecules, ATP, NADH, and water.
- There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
- Both aerobic and anaerobic creatures experience it.
- The initial process in breaking down glucose to release energy for cellular metabolism is called glycolysis.
- An energy-consuming phase and an energy-releasing phase make up glycolysis.
