Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds 
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
 One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions. 
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
 The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin. 
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
 
        
             
        
        
        
Answer:
1) Natural fibers come from many sources. These sources can include plants, animals, and minerals. We are probably most familiar with plant and animal fibers from a consumer standpoint. Common natural fibers sourced from the plant kingdom include cotton, flax, hemp, bamboo, sisal, and jute
2) Benefits of a high-fiber diet
Normalizes bowel movements. Dietary fiber increases the weight and size of your stool and softens it. ... 
Helps maintain bowel health. ... 
Lowers cholesterol levels. ...

<h2>cAMP and glucose mobilization</h2>
Explanation:
It would maintain high cAMP level and elevate glucose mobilization
- Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
- Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
- As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it 
- Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
- In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood
 
        
        
        
Answer:
The bacteria in our bodies help degrade the food we eat, help make nutrients available to us and neutralize toxins, to name a few examples[8]; [9]; [10]. Also, the microbiota play an essential role in the defense against infections by protecting the colonized surfaces from invading pathogens.
