Question

1.Type of fiber that slows gastric emptying and lowers blood glucose.

Polysassacharide

Soluble

HDL

Insoluble

2.What is meant by Amino Acid Sequence?

Number of side chains in the protein

Folding arrangement of the peptide chain

Order of amino acids in the peptide chain

Order of the essential amino acids in the protein

Answer 1

Answer [Q-1]: Soluble

Explanation: Soluble fibers delay the gastric emptying and also decrease the glucose absorption.

- This decrease in the rate of the glucose is done through alteration in the pancreatic and intestinal enzyme activity & gel.

Incorrect options:
- Option A: Polysaccharide are chains of monosaccharides. Starch, Glygogen, cellulose are some important polysaccharides. They come under the category of soluble nad insoluble fiber. Like cellulose is insoluble fiber, hemicellulose is water soluble fibers as well as insoluble fiber.

- Option C: HDL is a cholestrol and not fiber.

- Option D: Insoluble mainly increase the fecal bulk and increase the intestinal transit time. Example is starch.

Answer [Q-2]: Order of amino acids in the peptide chain.

Explanation: Amino acid sequence is a long chain of amino acid arranged in an orderly manner to form a polypeptide chain.

Incorrect options:

- Option A: Number of side chains decide the type of amino acid whether it is polar, nonpolar, neutral and various other types.

- Option B: Folding arrangement is to decide the types of protein structure: Primary, Secondary, Tertiary and Quaternary.

- Option D: There are 20 amino acids out of which 9 are essential amino acids. So, it is not necessary a peptide chain always consists of only these essential amino acids. It can be made out of combination of any 20 amino acids.
