Although the genes that cause LHON are found in cells throughout the body, LHON especially affects specific cells in the eyes an

d heart. Why do you think that tissues with these cells are among the first to fail as a result of defective mitochondria? How could a mitochondrial defect be related to vision and heart problems?Cite evidence

Answer:

Leber’s hereditary optic neuropathy (LHON) is defined as a disorder caused by a mitochondrial mutation that affects the visual and heart cells.

A  defective mitochondria is the primary cause of the LHON because it causes mtDNA is involved in the encoding of ubiquinone oxidoreductase         (subunits of NADH) that is the first complex of the electron transport chain. So, any defect or mutation in mtDNA causes neuronal defects.

<u>Mitochondrial defect due to mutation in amino acid exchanges in ubiquinone oxidoreductase affects optic nerves causing loss of retinal ganglion cells (RGCs) and their axons that leads to vison loss.</u>

<u>Mitochondrial biogenesis is the process in which mitochondrial ATP produced, and ATP transfer to heart and defect in mitochondrial biogenesis causes defect in heart cells.</u>

In two or more complete sentences explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps.
Basile [38]
First of all you have to make both sides of the equation equal

KClO3 -------- KCL + O2

this is the way i would do it first

K - 1                K - 1
Cl - 1               Cl - 1
O - 3                O-2   From this we can see that the oxygen of both don't equal

So than from this we would need to find the common factor of the oxygen which is 6. So we would multiply 3 by 2 to get 6 as well as 2 by 3 to get 6.
The equation will now look like
K - 1                         K - 1
Cl - 1                        Cl - 1
O - 3 (2) = 6             O - 2 (3) = 6

so the final answere:

KCl2O3 --------- KCl + 3O2
