b) from infoldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions

c) from the nuclear envelope folding outward and forming mitochondrial membranes

d) by secondary endosymbiosis

e) from engulfed, originally free-living proteobacteria

Answers

Answer:

e) from engulfed, originally free-living proteobacteria

Explanation:

The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!

According to the endosymbiotic theory of the origin of eukaryotic cells, mitochondria formed from engulfed, originally free-living proteobacteria. The correct option is e.

What is proteobacteria?

Proteobacteria are a major phylum (group) of bacteria. Pathogens such as Escherichia coli, Salmonella, Vibrio cholerae, Helicobacter pylori, and many others are among them.

Others are free-living, and they include many of the bacteria that fix nitrogen.

Proteobacteria, which includes mesophilic and neutrophilic bacteria, is the second largest phylum of hydrogenogenic CO oxidizers. Members of this phylum can be found in a variety of classes.

According to the endosymbiotic theory, mitochondria and chloroplasts were once free-living bacteria that were phagocytized but not digested by another cell.

According to the endosymbiotic theory of eukaryotic cell origin, mitochondria evolved from a rickettsia that was phagocytized but not digested by the larger cell.

Thus, the correct option is e.

Which region of the Ig molecule interacts with the antigen? What makes the region suited for this purpose?

Answers

Answer and Explanation:

Immunoglobulins (Ig) are proteins that are composed of 4 polypeptidic chains: 2 heavy chains (H) and two light chains (L). They assemble in a structure with a 'Y' form. This structure has two regions: the Fab region and the Fc region.

The region of Ig which interacts with the antigen is the Fab region. That is possible because the Fab region presents variability in the amino acid sequence which determines the specific complementary shape with the antigen structure (like a lock and the key).
