How can electron transport be described
mario62 [17]

The electron transport chain is a chemical reaction where electrons are transferred from a high-energy molecule to a low-energy molecule. These reactions can be used to convert energy from sunlight in photosynthesis or extract energy from sugars in respiration.

Klio2033 [76]

Answer:

The control group

Explanation:

The control group can be described as the group, which is being used to test any hypothesis or experiment,  in which there are no changes made by a researcher. It serves as a platform to compare the other groups and the changes occurring in them. All the results from an experiment are deduced by comparing the changes from the control group. Thus, every experiment investigation has a control group.

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2
rusak2 [61]

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

                                 <em>C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂</em>

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

  • <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place. </em>
  • <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
