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!

The extrinsic pathway is faster than the intrinsic pathway
The endoplasmic reticulum serves as a pathway for transport of materials throughout the cell. The endoplasmic reticulum is also associated with synthesis and storage.
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
Rough endoplasmic reticulum or Rough ER
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
The old pathway in the brain refers to well-established neural connections and habits, while the new pathway refers to forming new connections through learning and adaptation. The old pathway is efficient but can lead to automatic responses, while the new pathway allows for flexibility and personal growth. Stimulating the new pathway can help break free from old patterns and create new ways of thinking and behaving.

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.
