Question
* Proteins are
a. Polymers of amino acids that are connected by peptide bonds
b. Are involved in the catalysis of biochemical reactions
c. Have so called “side groups” that affect how amino acids interact
d. Answers (a) and (b) are both correct
e. Answers (a), (b), and (c) are all correct
* The glycolysis pathway and the tricarboxylic acid pathway (Krebs cycle) are commonly referred to as central metabolism. This is because:
a. these physiological reactions take place in the center of the a cell’s cytoplasm
b. essentially all carbon sources (amino acids, lipids, aromatic compounds, etc.) are metabolized by first transforming them into some intermediates of these two pathways
c. essentially all carbon sources are intermediates in either the EMP or the TCA pathways
d. answers (a) and (c) are both correct
Explanation / Answer
Q.1
Option E.
Proteins are polymers of amino acid that are connected by peptide bonds.
Enzymes are protein which catalyse the biochemical reaction.
Side chain of amino acid interact with one another in a polypeptide.
Q.2
Option B.
All carbon sources such as amino acid, lipids, aromatic compounds are metabolized by first transforming them into some intermediates of these pathway.
