What is the idea of devotion and loyalty to a country called that Africans

1. Perubahan dapat terjadi karena adanya interaksi manusia dengan lingkungan.

Lady bird [3.3K]

Answer:

Dampak negatif manusia terhadap lingkungan adalah:

Kelebihan penduduk, polusi, pembakaran bahan bakar fosil, dan penggundulan hutan. Perubahan seperti ini telah memicu perubahan iklim, erosi tanah, kualitas udara yang buruk, dan air yang tidak dapat diminum.

Dampak positif manusia terhadap lingkungan adalah:

Melindungi spesies yang terancam punah dan membersihkan danau dan laut memiliki efek positif terhadap lingkungan. Di rumah, Anda dapat membantu planet ini dengan mendaur ulang limbah dan menanam tanaman atau sayuran.

Briefly outline the steps involved in glycogen synthesis and breakdown and explain the regulatory mechanism involved in glycogen

Elenna [48]

Answer:

Glycogen is synthesized and degraded by different pathways, which provide greater flexibility for energy production through its degradation or for storage in its synthesis and thus maintain control of both metabolic pathways.

Explanation:

Synthesis and degradation pathways:

1º.- activation of glucose units at UDP-glucose.

UDP-glucose is an activated form of glucose, which is formed in a reaction catalyzed by UDP-glucose, which is formed in a reaction catalyzed by UDP-glucose pyrophosphorylase. This reaction is an example of biosynthetic reactions that are directed by the hydrolysis of pyrophosphate (PPi-2Pi).

Many biosynthetic reactions are directed by the hydrolysis of pyrophosphate, which catalyzes pyrophosphate hydrolase or pyrophosphatase, and is very favorable thermodynamically.

2nd.- polymerization or addition of glucose units to glycogen. Two steps: addition and branching.

UDP-glucose acts as the giver of glucose units for glycogen synthesis. Glucose transfer

from the UDP-glucose to a growing glycogen chain is catalyzed by glycogen synthase.

A branching enzyme [amyl (1,4 -> 1,6) -transglucosidase], moves a chain of about seven glucose residues, to form

bonds (α1-> 6) at the branching points.

To start glycogen synthesis, glycogen synthase is only effective when it is linked to glycogenin. Glycogenin is

an oligosaccharide carrier protein formed by glucose units with linkages (α1-> 4).

Oxygen must dissolve into fluid lining alveoli prior to diffusing into our pulmonary capillaries but we cannot breathe water. Ex

tamaranim1 [39]

Answer:

The strong hydrogen bonds in water made water stable and difficult to breakdown into constituent oxygen and hydrogen atoms. at a temprature less than 100 degree..

Oxygen is a strong electronegative atom than the two hydrogen atoms it is attached to in water. It pulls more electrons to itself than the hydrogen atoms.. This strengthened hydrogen bonds in water .

Consequently, it will be difficult for the needed oxygen atoms to simply diffuse into the alveoli to reach the blood,Compare to its molecular form where its atoms awere held by relatively week covalent bonds.

Besides the porosity of the thin alveolar endothelial walls of 0.2 micrometer is too small for the larger water molecules to pass through.
