There are 30 neutrons in a single Fe2+ atom
Molodets [167]3 years ago
4 0

Answer:

There are 30 neutrons in a single Fe2+ atom.

Explanation:

<u>The mass number is equal to the sum of the protons and the neutrons.</u>

M = Z + N

Where M is the mass number, Z is the number of protons, and N is the number of neutrons.

Using the periodic table, we know that the atomic number of Fe is 26.

<u>The atomic number is equal to the number of protons.</u>

56 = 26 + N

N = 30

There are 30 neutrons in a single Fe2+ atom.

Arrange the steps of glycogen degradation in their proper order. Hormonal signals trigger glycogen breakdown. Glucose 6‑phosphat
Otrada [13]

Answer: Please see answer below

Explanation:

The steps of glycogen degradation is as follows from this order.

--->Hormonal signals trigger glycogen breakdown.

1. Glycogen is (de)branched by hydrolysis of α‑1,6‑glycosidic linkages.

2. Blocks consisting of three glucosyl residues are moved by remodeling of α‑1,4‑glycosidic linkages.

3.[Glucose 1‑phosphate is cleaved from the non reducing ends of glycogen and converted to glucose 6‑phosphate.

--->Glucose 6‑phosphate undergoes further metabolic processing

The  degradation  of Glycogen follows  three steps:

(1) the release of glucose 1-phosphate from glycogen,

(2) the remodeling of the glycogen substrate to permit further degradation, and

(3) the conversion of glucose 1-phosphate into glucose 6-phosphate for further metabolism.
