What is the difference between De novo and salvage pathway of nucleotide synthesis?

∙ 16y ago
In De Novo pathways, the nucleotide bases are assembled from simpler compounds. The framework for a pyrimidine (= thymine and cytosine or uracil) base is assembled first and then attached to ribose. The framework for a purine (= adenine and guanine) base is synthesized piece by piece directly onto a ribose-based structure. In salvage pathways, performed bases are recovered and reconnected to a ribose unit.
To put it even simpler; in De Novo pathways, the bases of the nucleotides are made from scratch by using simpler starting materials (including amino acids). For this process, ATP hydrolysis is required. Salvage pathways recycle already used bases by reattaching them to a ribose. I hope this information helps answering your question!

Serves as a pathway for the transport of materials throughout the cell also associated with synthesis and storage?
The endoplasmic reticulum serves as a pathway for transport of materials throughout the cell. The endoplasmic reticulum is also associated with synthesis and storage.
What are the sources of NADPH required for fatty acid synthesis?
The Pentose Phosphate Pathway, in which Glucose-6-phosphate Dehydrogenase catalysizes the oxidation of Glucose-6-phosphate and NADP serves as the electron donor is a source of NADPH. The citrate-malate shuttle between the mitochondria and the citosol is an additional source.http://www.answers.com/pentose+phosphate+pathway

What is difference between the professional career pathway and the entry career pathway?
A professional career pathway requires a few years of education, such as high school diploma or even a college degree. An entry career pathway will usually not have many requirements.
