Answer:

D. partial pressure of oxygen

Explanation:

Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.

In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.

Thus, Option-D is correct.

. Which biomolecules do not function in supporting a cell?
charle [14.2K]

Answer:

Generally  the primary organic molecules  in cells which support the metabolic and biochemical process of the cells are bio molecules Theses are Carbohydrate

Protein

Lipids

and Nucleic acids of DNA  and RNA. They can also be the  minute  hormones and metabolites present in the cells.

Generally, CHO provide  structural supports to the cells,and acts as sources of energy.

Protein forms most enzymes for biochemical reactions,and aids movements, through muscle contractions. Besides,muscles are made of protein.Therefore protein forms the  structural basis of the muscles.This aids movement and locomotion for support.

Lipids are the richest source of energy for the cell,and provides support the cells membrane.

The nucleic acids,are primary concerned with the transfer of inheritable characteristic from mother cells to the daughters during  reproduction.While the DNA is the genetic information been transferred,the RNA is the vehicle  for transmission of the genetic information as protein  from the parents' nucleus to the offspring. Thus the nucleic acid roles it for transmission of  genetic information as genes,(DNA) and translation of these genes as proteins(RNA).Hence,Nucleic acids  does not participate in the cells' support.

Therefore
