Why is MgATP2− , instead of ATP4− , a substrate for the hexokinase reaction? Select two correct phrases. Mg2+ prevents ATP hydro

lysis. Hexokinase cannot bind ATP when it is not complexed with Mg2+ . Mg2+ makes the ???? (terminal) phosphorus atom of ATP more accessible to electrophilic attack by a glucose –OH group. Mg2+ shields the negative charges of two of the phosphate oxygen atoms of ATP. Mg2+ makes the ???? (terminal) phosphorus atom of ATP more accessible to nucleophilic attack by a glucose –OH group.

Answer:

Mg is able to give off two of its electrons to other molecule, not four. ATP, in this case is the aceptor of those electrons

Two correct answers are:

1) Hexokinase cannot bind active ATP when it is not complexed with Mg2+

2) Mg2+ makes the terminal phosphorus atom of ATP more accessible to nucleophilic attack by a glucose-OH group

Explanation:

As Mg occurs naturally as ion Mg++, it is able to give off only two of its electrons to other molecule, then it is possible for ATP to receive two electrons of Mg, forming MgATP2-

The hexokinase reaction, here cited, corresponds to the glucose phosphorylation of its sixth carbon to produce glucose-6-P, which is a glycolysis intermediate. In this way glucose is activated (ATP is initially invested to energize glucose).  Later on, Glyceraldehide-3-P is produced, and finally converted to pyruvate, NADH2 and ATP

<h3>What is eukaryotic cell?</h3>
  • Eukaryotes are organisms having cells that contain a nuclear envelope around their nucleus.
  • They are a member of the Eukaryote class of organisms.
  • One of the three domains of life is the eukaryotic domain.
  • The other two are the bacterial and archaeal domains.
  • Organisms called eukaryotes have nuclei and membrane-bound organelles in their cells.
  • Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
  • Eukaryotes are multicellular or unicellular organisms.
  • The primary distinction between these two categories of organisms is that eukaryotic cells have a membrane-bound nucleus while prokaryotic cells have not.
  • The nuclei of eukaryotes house their genetic material.
