What happens to the concentration of H+ in the intermembrane space and the matrix as electrons move down the ETC?

Biology

Delicious77 [7]3 years ago
6 0
In electron transport chain, the multiprotein structure pumps out H+ ions into the intermembrane space. As the H+ ions get pumped out, the concentration of H+ in the intermembrane space gets higher. As a result, H+ ions will start flowing down back to the chromosomes matrix through the ATP molecule.

Compare and contrast the role of secretory vesicles, the lysosome, and the peroxisome.
Daniel [21]

Lysosomes ( common in animal cell but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion in white blood cells that eat bacteria) lysosomes contents are carefully released Into the cytoplasm can also cause cell death.  

Peroxisomes: this organelle is responsible for protecting the cell form its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria .The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.

Secretory vesicles: cell secretions –e.g, hormones, neurotransmitters, are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for releases.

Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individ
Ne4ueva [31]

 Answer:

<u> The following four traits are -: </u>

  • <u>Pedigree 1 -</u> A recessive trait (autosomal recessive)  is expressed by pedigree 1.
  • <u>Pedigree 2- Recessive inheritance is defined by Pedigree 2. </u>
  • <u>Pedigree 3</u> - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
  • <u>Pedigree 4-</u> An X-like dominant trait is expressed by Pedigree 4.    

Explanation:

<u>Explaination of each pedigree chart</u>-

  • Pedigree 1 demonstrates the <u>recessive trait </u>since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. X^A In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
  • <u> Recessive inheritance</u> is defined by <u>Pedigree 2</u>. This is<u> X-related inheritance as autosomal recessive</u> inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical  Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes (X^A) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical X^A must be contributed by II-6.
  • The inheritance of the<u> dominant trait</u> is demonstrated by <u>Pedigree 3 </u>because affected children still have affected parents (remember that all four diseases are rare). The trait must be <u>autosomal dominant</u> because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
  • <u>Pedigree 4</u> is an <u>X-linked dominant function</u> characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.    

In the question the pedigree chart was missing ,hence it is given below.
