In my opinion, the correct answer among the choices listed is option C. The members of the kingdom Protista are least similar to a bacteria. Protists are eukaryotic organisms which cannot be classified as a fungus, animal, or a plant. They are mostly unicellular organisms.
NAD +molecule
Explanation:
Krebs cycle and electron transport chain are important steps in cellular respiration.
In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.
NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.
Now in the Krebs cycle, it is ready to take electrons again.
<span>Autosomes are
non-sex chromosomes, meaning they are non-sex determining chromosomes inside
cells. Humans naturally have 46 chromosomes in each body cells; 44 of these are
actually autosomes that a person inherits from his/her parents. All persons get
22 autosomes from the mother and the other 22 autosomes will be coming from the
father. These autosomes always come in pairs and since everyone has 44 of these
autosomes in their cells, it should be noted that there are only 22 types that
are obviously numbered from 1 to 22. </span>
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
