Suppose an alien life form is discovered on another planet that takes in CH4 from the atmosphere. Which of the following could b
sladkih [1.3K]

The right answer is B

A radiotracer is an entity composed of a carrier molecule and a detectable radioactive isotope using devices such as gamma cameras or positron emission tomography.

A radiotracer is either a radioactive isotope alone or the combination of a molecule and a radioactive isotope. In this case, it is said that the molecule is labeled by the radioactive isotope.

A radioactive isotope is an atom whose nucleus, unstable, emits radiation. It could be :

- alpha radiation consisting of two protons and two neutrons.

- a beta radiation consisting of a negative electron (beta) or a positive electron (beta +, positron).

- a gamma radiation consisting of a high energy photon.

Dab most likely inhibits which reaction?a. phosphorylation of glucose. phosphorolysis of glycogen. export of lactate from cellsd
Pie

Dab most likely inhibits phosphorolysis of glycogen reaction.

<h3>What is phosphorolysis?</h3>
  • Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
  • It's comparable to hydrolysis.
  • A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
  • It's comparable to hydrolysis.
  • Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
  • The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
  • The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
  • It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.
