What are anaplerotic reactions and why are they important? If a bacterial cell was actively synthesizing amino acids, would you expect more or less PEP carboxylase activity? Why
Homework Answers
Anaplerotic reaction are chemical reactions which forms intermediate substrates to the metabolic reactions. For example TCA cycle intermediates formation. PEP carboxylase will adds CO2 to PEP and forms Oxaloacetate(OAA) a starting compound of TCA. Which combined with Acetyl CoA and forms Isocitrate.
Here Some of PEP converts into Pyruvate and finnally forms Acetyl CoA but to meet the demand some of the PEP converts into OAA by PEP carboxylase.
We know TCA intermediates are hub for metabolism and its increased flux is essential for biosynthesis of various molecules and amino acids.

A scientist injected a gene into a bacterial cell, expecting it to synthesize functional protein product of that gene. But rather the protein product was nonfunctional and contained more amino acids than the human gene created in a eukaryotic cells. Why did this happen, please explain as much as you can. Thank you

a) You cut a gene out of the DNA of a eukaryotic cell and insert it into the DNA of a bacterial cell. You find that the bacteria do not produce the protein you wanted but instead, a much larger disorganized protein is produced. Explain what happened. b) Your teammate claims to have found a mutation in the serine tRNA synthetase that causes serine amino acids to be linked to a tRNA with a UAA anti-codon. Is this possible? If so,...
