Arrange the sequence of events for the overall mitochondrial respiratory assembly in the correct order.
kotykmax [81]

Answer:

Option D, 4,2,1, 3

Explanation:

The mitochondrial respiratory chain (MRC) comprises of four membrane bound complexes and it involves the following steps

a) RC complexes (RCC) I and II reduces the RC’s equivalent where RCCI i.e receives electron from the NADH.  

b) These electrons are then transferred to the flavin mononucleotide factor and then passed on to the Fe-S embedded cluster .

c) These electron reduces the coenzyme Q  to ubiquinol  

d) With in the inner mitochondrial membrane (IMM), protons are trans located from IMM to the  intermembrane space (IMS)

e) RC complex II then transfer electron from succinate to the cofactor FAD

f) From FAD proton are transferred to the FeS cluster and on the other hand electron move from QH2 to the RC complex III

g) This RC complex III give its electrons to the cytochrome and they are further passes on to the RC complex IV

h) With four redox centers, the terminal RC complex translocate protein by using energy produced in electron transfer thereby converting oxygen into water.

Hence, the correct option is D

Which of the following is the best reason to protect a section of an oak forest?
Alla [95]

Answer:

<em>The correct option is D) to maintain the diversity of the living environment</em>

Explanation:

Forests, such as the oak forest, are of utmost ecological importance as they are rich in wild-life animals and plants. They biodiversity in such areas is huge as there are different types of plants and animals living here. Even if we have to cut down a forest, we should try to protect a section of it so that all this huge biodiversity is not lost. Cutting down the whole oak forest will result in no habitat for the different animals that lived there. As a result, many species of organisms might become extinct.

when a neurotransmitter opens a chemically gated ion channel that allows sodium to enter the postsynaptic cell, the result is an
KatRina [158]

This will result to an excitatory postsynaptic potential ((EPSP)

Neurotransmitters are those chemical messages that transmits signals from nerve cells to their target cells.

Neurotransmitters are packed inside vesicles at the presynaptic nerve terminal.

The arrival of an action potential at this terminal leads to opening of Voltage gated channels.

This leads to a change in membrane voltage of the postsynaptic cell following the influx of positively charged ions (sodium ion) into the cell which is called the excitatory postsynaptic potential.

Therefore, excitatory postsynaptic potential ((EPSP) occurs when a neurotransmitter opens a chemically gated ion channel that allowing sodium to enter the postsynaptic cell.
