The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second. The nuclear binding energy curve.

I hope this helps

This is where fusion in the Sun happens. Every second, 600 million tons of hydrogen are being converted into helium. This reaction releases a tremendous amount of heat and energy. The process of fusion in the Sun is known as the proton-proton chain.

Producers are plants. Plants make energy from the sun through the process of photosynthesis and other living things (such as animals) eat the grass (known as grazing)

Sveta_85 [38]

I think the correct answer would be diarrhea. It is often a result of consumption of contaminated food and drinks. And each year, it was estimated that approximately 2 million children died due to this. It is a condition where bowel movements are frequent and is in liquid form which would lead to dehydration.

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).
