Answer:

NADH and FADH2

Explanation:

Energy is released in glycolysis and krebs cycle in the form of NADH and FADH2 ,electron transport chain transforms this energy into ATP

Endosymbiotic theory is supported by similarities between chloroplasts and * Cyanobacteria Viruses Yeasts None of the above
stiv31 [10]

Answer:

Endosymbiotic theory is supported by similarities between chloroplasts and * Cyanobacteria.

Explanation:

The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living bacteria that were phagocytized by another cell but not digested. These bacteria got to adapt to their host, and both cells became interdependent.  

Both organelles have many similarities with other free-living bacteria. Chloroplasts probably derivate from cyanobacteria because both cells absorb sunlight, produce ATP, and organic molecules. And mitochondria derivate from rickettsias because they produce ATP in the same way by using the Krebs Cycle and Oxidative Phosphorylation.

From the phagocytosis moment, these two cells became so dependant on each other, they could not survive without the other one.  

Chloroplasts and mitochondria share some traits with free-living bacteria, that support the theory.  

• Both organelles present their genetic material. This DNI is independent of the cells´ DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells.

• Both organelles divide by binary fission, not by mitosis, and can synthesize their ribosomes and organelles.    

• Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one.  

In fact, in this internal membrane are placed the energy centers, just as it occurs in bacterias membrane.  

• Finally, the sizes of the organelles are similar to the size of some procaryotes

True [87]

Answer:

Ribosomes,cytoplasm ,cell wall and circular DNA could be used to justify that the cell is a prokaryote.

Explanation:

Ribosome  Ribosome is present in both prokaryotic cell and eukaryotic cell.The prokaryotic cell 70S ribosome which contain 2 subunits the larger subunit is 50S and the smaller subunit is 30s

Cell wall  Prokaryotes such as bacterial cell contain cell wall.Cell wall  of bacteria contain various carbohydrates which are crosslinked with peptides resulting in the formation of peptidoglycan.

Cytoplasm The cytoplasm of prokaryotic cell such as bacteria contain ribosomes,chromosome and extracellular genetic material called plasmid.

Circular DNA Almost all prokayotic chromosome contain circular DNA molecule that does not contain any free ends.
