Two protons are translocated across the inner mitochondrial membrane by complex iv for every pair of electrons passing through the electron transport chain.

<h3>What is inner mitochondrial membrane?</h3>
  • The mitochondrial membrane that divides the intermembrane gap from the mitochondrial matrix is known as the inner mitochondrial membrane (IMM).
  • As a result, the inner mitochondrial membrane maintains the proton gradient that powers oxidative phosphorylation and serves as a functional barrier to the passage of tiny molecules between the cytosol and the matrix.
  • Cristae are the name for the inner membrane folding of mitochondria.
  • They broaden the surface.
  • The inner or cytoplasmic membrane controls the flow of nutrients, metabolites, macromolecules, and information into and out of the cytoplasm and preserves the proton motive force necessary for energy storage.
  • It is impermeable to polar molecules.
  • The inner membrane of E is connected to more than 100 distinct proteins.
  • Similar to the cell membrane, the mitochondrial inner membrane is mostly composed of a phospholipid bilayer.
  • Several proteins that function to carry out the electron transport chain are embedded in this bilayer.
  • The membrane's surface area is increased by folds called christae.

Which statement about the molecules in ice and water is correct?
Assoli18 [71]
The molecules in ice are close together and do not have any movement, or energy at all (frozen). The molecules in water are apart from each other and do have motion and energy. The molecule in gas or vaporization, are far apart from each other, have rapid movement, and have a great amount  of energy. Just think that the lighter the liquid state of matter gets, the more energy and motion it has.

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells fo
lora16 [44]

Answer:

B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.

Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.

Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.

Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.

Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathin
Ahat [919]

About the question:

You will find the pedigree in the attached files

Answer:

  • individual 4 → Affected woman → Black circle
  • individual 5 → Affected woman or man → Black circle or square
  • individual 7 → Healthy woman → Empty circle
  • individual 10 → Affected boy → Black Square

Explanation:      

Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.

<em>Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny</em>, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.

Before answering the question, let us remember the pedigree symbols.

  • Squares represent Males/Men
  • Circles represent Females/Women
  • Empty symbols represent healthy/non-affected individuals
  • Solid black symbols represent sick/affected individuals

In the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the <em>disease is mitochondrially inherited</em>.

Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple <em>had one boy and two girls</em>. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).  

On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.      

And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.
