Answer:

Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

Tems11 [23]

Answer:

The star could also be said to be 360 Million Million miles from the earth's sun.

Explanation:

A light year equals 9.4607 × 10^{12} km.

This is also approximately 6 Million Million Miles.

If we expressed the answer in miles, then we have to multiply 6 by 60.

This is equals to 360.

Therefore, 60 Light years is approximately 360 Million Million miles.

Cheers!

Burka [1]

Answer:

The correct answer is biopsychosocial model.

Explanation:

An interdisciplinary model that provides an interrelation between the psychological, biological and socio-environmental elements is known as the biopsychosocial model. The model illustrates the facts that how the association between the mentioned factors plays an essential function in the fields of health and development of humans.  

The model was postulated by George Engel in 1977 and is the first of its type to illustrate this kind of multidisciplinary thinking. However, the model has been rejected by many, but still, it has an influence in the fields of health, medicine, psychology, and the development of human beings.

The TCA cycle in a particular tissue has been inhibited by fluoroacetate. However, it is not the fluoroacetate that is responsib
denis23 [38]

Answer:

TCA cycle in particular is inhibited by fluoroacetate. Fluoroacetate is a compound the binds to the Coenzyme A of the Krebs cycle to form Floroacetyl CoA which in turn forms fluorocitrate instead of forming citrate. This fluorocitrate is not able to bind to aconitase enzyme preventing the conversion in to isocitrate, thereby halting the Krebs cycle.

a) The inhibitor molecule here is Fluorocitrate.

t a Coa-sa Co ASH Coenzyme A Fro Nat Fluoroacetate Fluoroacetyl COA Citrate Hooc-ch-F Hooc-c-one Hooc-ch, Fluoro citrate

b) see attachment below

c) The fluoroacetate along with Coenzyme A forms Fluoroacetyl CoA which in turn forms Fluorocitrate in place of citrate formation. Fluorocitrate does not bind to Aconitase hance isocitrate is not formed and the Krebs cycle in halted.

See attached file for the continuation of c.

The above mechanism shows the inhibition of aconitase, where the presence of fluorine causes resonance to occur after the flip step preventing the Ser 642 moiety of Aconitase from binding and no isocitrate conversion.

d) As compared to the normal tissues the, due to the inhibition of aconitase enzyme, the citrate isocitrate conversion will proceed at a very slow rate thereby halting TCA cycle and the concentrations of the further produced components:

Citrate concentration increased

Isocitrate concentration reduced

Alpha - ketoglutarate concentratioin reduced

Succinyl CoA concentration reduced

Succinate concentration reduced

Fumarate concentration reduced

Malate concentration reduced

Oxaloacetate concentration reduced
