What advantage is there to phosphoglycerate kinase having an open and closed configuration?
Andrej [43]

Answer:

The correct answer is "The induced-fit mechanism maximizes accessibility of active site without sacrificing hydrophobic environment".

Explanation:

Phosphoglycerate kinase is an enzyme that participates in a step of glycolysis by transferring a phosphate group from 1,3-bisphosphoglycerate (1,3-BPG) to ADP, generating the following intermediary compound and a molecule of ATP. The phosphoglycerate kinase has an open and closed configuration, which has the advantage that the induced-fit mechanism maximizes accessibility of active site without sacrificing hydrophobic environment. This help the enzyme to have a more stable configuration and regulates its use in glycolysis.

I am a multicellular organism. I am heterotrophic and rely on oxygen to metabolize my food. I belong to Kingdom
Fynjy0 [20]

Answer:

Kingdom Animalia

Explanation:

Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).

In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions. Therefore, a heterotrophic multicellular organism that relies on oxygen to metabolize its food belongs to KINGDOM ANIMALIA

Occasionally a child is born with an extra chromosome 13, but never do you see a child with an extra chromosome 12, why?
Morgarella [4.7K]

This is because some of the trisomies (one extra chromosome, three instead of two) are fatal, births cannot survive.

Theoretically, trisomies can occur with any chromosome, but often result in miscarriage.

The types of autosomal trisomy that survive to birth in humans are:

Trisomy 8 or Warkany syndrome 2

Trisomy 9

Trisomy 13 or Patau syndrome

Trisomy 18 or Edwards syndrom

Trisomy 21 or Down syndrome.
