Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
<span>An example of an epithelial tissue where gases are exchanged is alveolar epithelium, which can be found in the lungs. This tissue is simple epithelial tissue. This is to be expected because the cell layer needs to be thin enough for the gasses like carbon dioxide and oxygen to diffuse or pass through. Stratified epithelial tissue contains several cell layers that would impair the exchange of gasses.</span>
Answer: The correct answer is Kreb cycle.
Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).
It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.
Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.
On the contrary, glycolysis and fermentation occur in the cytoplasm.
Thus, mitochondria is host to Kreb Cycle of the cellular respiration.
Answer:
Accessing food because while they lay on the ocean floor they search for foods and use the water to digest it
