The velocity of any gas particles is inversely proportional to the molecular mass of the the gases. Lighter gases posses higher kinetic energy than heavier gases. From the list given, Neon is the lightest of the four gases with an atomic mass of 4.03 thus it is the lightest. Velocity contributes to the Kinetic energy of the particle. Thus A) Neon is the correct answer.
Answer:
A metabolic pathway
Explanation:
Biologically, a metabolic pathway is a series of chemical reactions in which the end product of a reaction serves as a substrate (or reagent) for the reaction thereafter, the reactions being interdependent with one another. These reactions are catalyzed by enzymes. The metabolic pathways are fundamental for the maintenance of the cell and consequently of the body's homeostasis.
An example of the metabolic pathway can be seen in the above question where glucose is converted to glucose 6-phosphate by hexokinase. Glucose 6-phosphate then serves as a substrate for the enzyme phosphoglucose isomerase, which converts this reagent to fructose 6-phosphate. Fructose 6-phosphate serves as a substrate for phosphofructokinase, which converts fructose 6-phosphate into fructose 1,6-bisphosphate.
