How does fermentation allow the cell to continue to make atp when oxygen is not present?
kap26 [50]

Explanation:

Usually most cells that carry anaerobic respiration utilize the Glycolysis pathway because it does not require oxygen. It is also believed it is the ancient metabolic pathway by utilized by primordial cells  when the earth's atmosphere was not mainly oxygen,  

Glycolysis consumes 2 ATPs (during the conversion of Glucose to Fructose 1,6 bisphosphate ) but produces a gross $ ATPs. It, therefore, has a net ATP of 2. This is inefficient when compared to the Krebs cycle that utilizes oxygen to produce 34 ATPs. Anaerobic respiration produces pyruvate. This pyruvate is broken down into an organic acid like lactic acid which is excreted from the cell, which is why fermented food tastes sour.

Reaching 29,029 feet (8,848 meters) above sea level, Mount Everest is the highest mountain on Earth. Located in the Mahalangur section of the Himalayas, the mountain's summit straddles the border separating China and Nepal.

Or if you want a more literary description, try some devices to describe it i.e what's there, the atmosphere, the height/gradient etc.

Cohesion, adhesion, and surface tension are characteristics of water that ________. increase when pH increases increase when tem
Ray Of Light [21]

Answer:

are a result of hydrogen bonding.

Explanation:

The <em>surface tension</em><em> is the amount of energy required to stretch or increase the surface of a liquid by a unit area</em>. <u>Liquids that have strong intermolecular forces also have high surface tensions.</u> Thus, because of hydrogen bonding, water has a considerably greater surface tension than most other liquids.

Another example of surface tension is capillary action. A thin film of water adheres to the wall of the glass tube. The surface tension of water causes this film to contract, and as it does, it pulls the water up the tube. Two types of forces bring about capillary action.

One is <em>cohesion</em><em>, which is the intermolecular attraction between like molecules (in this case, the water molecules)</em>. The second force, called <em>adhesion</em><em>, is an attraction between unlike molecules, such as those in water and in the sides of a glass tube</em>. If adhesion is stronger than cohesion, the contents of the tube will be pulled upward. This process continues until the adhesive force is balanced by the weight of the water in the tube.

This <u>characteristics of water are a consequence of a particularly strong type of intermolecular attraction, called the </u><u>hydrogen bond</u><u>, which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.</u>

Write the balanced NET ionic equation for the reaction when chromium(III) bromide and sodium phosphate are mixed in aqueous solu
Mariulka [41]

The balanced NET ionic equation for the reaction is CrBr₃(aq) + Na₃PO₄(aq) ==> CrPO₄(s) + 3NaBr(aq)

<h3>What is a balanced Ionic equation ?</h3>

In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.

Additionally, the net charge is the same on both sides of the equation.

Separate into the complete ionic equation.

It should be obvious that the aquous solutions ionize and the solid is shows as the molecule since it doesn't dissolve.

Cr³⁺(aq) + 3Br⁻(aq) + 3K⁺(aq) + PO₄³⁻(aq) ==> CrPO₄(s) + 3K⁺(aq) + 3Br⁻(aq)

Now look and cancel those ions common to both sides. What is left is the net ionic equation.

Cr³⁺(aq) + PO₄³⁻aq) ==> CrPO₄(s)
