slamgirl [31]
Talking of taxonomic kingdoms, the organism belongs to kingdom Animalia. Among other kingdoms, Archaea, Bacteria, and Protozoa are unsuitable since they include unicellular organisms. This organism can move freely from place to place, thus, it couldn't be neither Plantae nor Fungi, leaving Animalia as the only matching kingdom.

Most protein purification procedures require that all steps be done at refrigeration temperatures (4 °C). This is done partly to
svlad2 [7]

Explanation:

A protein purification is a series of processes that allow the isolation of a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function, structure interactions of the protein of interest, for example an enzyme a cell receptor or an antibody. The initial material is generally a biological tissue or a microbial culture. There are several steps in the purification process; it can release the protein from the matrix that confines it, separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all the others. This last step may be the most laborious aspect of protein purification.

Techniques used

Homogenization

Cell fractionation

Reversible denaturation with ammonium sulfate

How many molecules of glucose is needed to undergo cell respiration?
masya89 [10]

Answer:

<em><u>One molecule of glucose is needed to produce approximately 38 molecules of ATP in each round of aerobic respiration.</u></em>

Explanation:

In respiration, organisms use food, or glucose made in photosynthesis to obtain energy. Photosynthesizing organisms use light to synthesize chemical energy.

Mitochondria in some organisms provide the most favorable environment for energy metabolism, glucose undergoes a form of combustion, this results in carbon dioxide and water production, together with energy as ATP or adenosine triphosphate.  

<h3> </h3><h3>C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP </h3>

<em>    glucose+ oxygen                      →  carbon dioxide+ water+ energy </em>

Thus, only one molecule of glucose is needed to produce approximately 38 molecules of ATP.
