Answer:

d. A centrifuged sample of blood would yield a composition of 45% plasma and 55% cells

Explanation:

Blood is a mixture of plasma and formed elements. Plasma consists of the fluid portion of the blood and approximately makes up 55 percent of the blood. On the other hand, the formed elements are the red blood cells, white blood cells, and platelets which make up about 45 percent of blood.

Of the following lists of electron transport compounds, which one lists them in order from the one containing electrons with the

notsponge [240]

Answer:

B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2

Explanation:

FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.

NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.

So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.

51. how do the differences in amino acid sequences lead to different protein functions?

Setler [38]

DifferentDifferent amino acid produce different proteins based on the bonds formed between them .

<h3>How does the sequence of amino acids affect the functions of protein ? </h3>

The sequence of amino acid of a protein determines protein shape , since the chemical properties of each amino acids are forces that gives rise to intermolecular interaction to begin to create secondary structure .

Amino acids are monomers of protein. So , different amino acids produce different proteins based on the bonds formed between them.
