Metabolism is all chemical reactions that occur in organisms, including those that occur at the cellular level.

<h2> Further Explanation </h2>

The three main goals of metabolism are:

  • Converting food into energy to run cellular processes.
  • Conversion of food / fuel into a constituent of proteins, lipids, nucleic acids and some carbohydrates.
  • Nitrogen waste disposal. The reaction catalyzed by this enzyme allows the organism to grow and multiply, maintain its structure, and respond to its environment.

In general, metabolism has two directional trajectories for organic chemical reactions:

catabolism, which is a reaction that breaks down molecules of organic compounds, such as the breakdown of glucose into pyruvate by cellular respiration;

anabolism, which is a reaction that assembles (synthesis) organic compounds such as proteins, carbohydrates, lipids, and nucleic acids from certain molecules.

Catabolism is a series of metabolic processes that break down large molecules, including breaking down and oxidizing food molecules. The purpose of catabolic reactions is to provide the energy and components needed by anabolic reactions in order to build molecules.

Anabolism is a metabolic pathway that arranges several simple organic compounds into chemical compounds or complex molecules. This process requires outside energy. The energy used in this reaction can be either light energy or chemical energy. The energy, then used to bind these simple compounds into more complex compounds. So, in this process the required energy is not lost, but stored in the form of chemical bonds in the complex compounds formed.

A 265-mL flask contains pure helium at a pressure of 751 torrs. A second flask with a volume of 465 mL contains pure argon at a
Nadya [2.5K]

Answer:

Total Pressure = 745.6 torr

Partial Pressure of He = 272.8 torr

Partial Pressure of Ar =  472.8 torr

Explanation:

Step 1: Data given

Volume of the flask helium = 265 mL

Pressure in the helium flask = 751 torr = 751/760 atm

Volume of the flask argon = 465 mL

Pressure in the argon flask = 727 torr = 727/760 atm

The total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture.

Step 2: Calculate total volume

Total volume = 265 mL + 465 mL = 730 mL =  0.730 L

Step 3: Boyle's Law:

P1V1=P2V2

⇒ with P1 = total pressure gas exerts in its own flask

 ⇒ with V1 = volume of flask with stopcock valve closed

 ⇒ with P2 = partial pressure of gas exerts on total volume of both flasks when stopcock valve is opened  

 ⇒ with V2 = total volume of both flasks with stopcock valve opened

Helium using Boyle's Law equation from above:

P1V1=P2V2

⇒ with P1 = Pressure of helium = 751 /760 = 0.98816 atm

 ⇒ with V1 = volume of helium = 0.265 L

 ⇒ with P2 = The new partial pressure of helium

 ⇒ with V2 = total volume = 0.730 L

(0.98816 atm)(0.265L)=P2(0.730L)

P2=0.359 atm

Argon using Boyle's Law equation from above:

P1V1=P2V2

⇒ with P1 = Pressure of argon = 727/760 = 0.95658 atm

 ⇒ with V1 = volume of argon = 0.465 L

 ⇒ with P2 = The new partial pressure of argon

 ⇒ with V2 = total volume = 0.730 L

(0.95658 atm)(0.465L)=P2(0.730L)

P2=0.609 atm

Step 4: Convert pressure in atm to torr

Pressure helium = 0.359 atm = 272.8 torr

Pressure argon = 0.609 atm = 472.8 torr

Step 5: Calculate Total pressure

Ptotal = P(He)+P(Ar)

⇒ Pt  = total pressure of the gas mixture

⇒ P(He) = partial pressure of Helium

 ⇒ P(Ar)  = partial pressure of Argon

Pt = 272.8 torr + 472.8 torr

Pt = 745.6 torr

Total Pressure = 745.6 torr

Partial Pressure of He = 272.8 torr

Partial Pressure of Ar =  472.8 torr
