Answer:
A. Phospholipid bilayer
Explanation:
Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.
The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
Answer: Digesting food is a chemical change.
Explanation:
Chemical changes cannot be undone so digesting the food is considered a chemical change.
The host cell bursts to release the newly formed virus particles and then it dies.
Answer:
C. oxidative deamination requiring NAD⁺.
Explanation:
Oxidative deamination is the first step in breaking down the amino acids in order to be converted into sugars. This process begins by removal of amino group of the amino acids. The amino group then becomes ammonium as it is lost and subsequently, undergoes the urea cycle to become urea in the liver. From there, It is released into the blood stream, where it is transferred to the kidneys, which will secrete the urea as urine.
The remaining portion of the amino acid becomes oxidized, forming an alpha-keto acid. The alpha-keto acid thus proceed into the Citric acid cycle, in order to produce energy.
The alpha-keto acid can also enter glycolysis, where it will be eventually converted into pyruvate. The pyruvate is then converted into acetyl-CoA so that it can enter the Citric acid cycle cycle and convert the original pyruvate molecules into ATP, or usable energy for the organism.
