. Which of the following is not involved in the biosynthesis
of a protein molecule?
1. Codon
2. Ribosome
3. Messenger RNA
4. Amylase - correct answer- 4
The biosynthesis of a protein molecule uses information
encoded in genes. The amino acid sequence of the protein
is delineated by the nucleotide sequence of the gene that
encodes the protein. Codons, sequences of three adjacent
nucleotides along a DNA or messenger RNA molecule,
designate the specific amino acid to be incorporated into
a polypeptide.
A catabolic enzyme:
1. Joins two or more substances into a larger molecule
2. Cleaves a molecule into two or more parts
, 3. Inserts a substance between two or more existing
molecules
4. Acts as a chemical messenger between amino cells -
correct answer- 2
A catabolic enzyme engages in destructive metabolism,
which involves degrading or breaking down complex
molecules into simpler ones with the resulting release of
energy. In the body, the breakdown of food in the
gastrointestinal tract by a variety of digestive enzymes is
an example of a catabolic process. The opposite of
catabolism is anabolism.
A proteolytic enzyme has the following action:
1. It cleaves complex sugars into simple sugars.
2. It joins fatty acids into proteins.
3. It joins proteins to sugars to form glycoproteins.
It cleaves protein molecules into smaller units -
correct answer- 4
Proteolytic enzymes, also known as proteases, catalyze
the splitting or breakdown of proteins into smaller
peptide fractions and amino acids. The process of
accomplishing this breakdown is called proteolysis.
