Question
These are simple true and false reasoning biochemistry questions, so please help.
True or False (explanation) (15 pts)
a). Feedback inhibition and feedback repression are two processes for metabolic regulation and they are fundamentally the same.
b). Bacteria can be used for protein production with much a lower cost than using animal cells, therefore, the production of therapeutic antibody using bacteria needs to be highly encourage.
c). Aerobic process of glucose can take place in both prokaryotic and eukaryotic cells, but the energy efficiency is lower in prokaryotic cells.
d) Glycolysis can take place in both prokaryotic and eukaryotic cells, but the energy efficiency is lower in prokaryotic cells.
e). Ribosome is a critical components for protein synthesis, because it is a very large protein.
Explanation / Answer
Question - a). Feedback inhibition and feedback repression are two processes for metabolic regulation and they are fundamentally the same.
Answer - True because a product in excess in metabolic system will repress the enzyme called feed back repression which inturn inhibits the metabolism called feedback inhibition.
b). Bacteria can be used for protein production with much a lower cost than using animal cells, therefore, the production of therapeutic antibody using bacteria needs to be highly encourage.
Answer - True, because bacteria can be easily culture in basic laboratory conditions but animal cell culture requires advance systems and laboratory condition are very expensive.
c). Aerobic process of glucose can take place in both prokaryotic and eukaryotic cells, but the energy efficiency is lower in prokaryotic cells.
Answer - False because prokaryotes produces 5ATPs, where as eukaryotes produces 3ATPs from 2NADH Molecules of glycolysis @ Electron Transport System
d) Glycolysis can take place in both prokaryotic and eukaryotic cells, but the energy efficiency is lower in prokaryotic cells.
Answer - False because prokaryotes produces 5ATPs, where as eukaryotes produces 3ATPs from 2NADH Molecules of glycolysis @ Electron Transport System
e). Ribosome is a critical components for protein synthesis, because it is a very large protein
Answer - False because Ribosome is not protein alone it is the combination of Ribonucleic acid & few proteins containing Catalytic property ( Enzymatic ability - peptidyl transferase) at larger subunit. so involved in protein synthesis, similarly smaller sub unit has anti shine dalgarnow sequence binds to mRNA . so Ribosome is a critical components for protein synthesis
