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

Where does the pentose phosphate pathway occur?
The pentose phosphate pathway occurs in the cytoplasm of cells. It is a metabolic pathway that generates NADPH and produces ribose-5-phosphate, which is important for nucleotide synthesis and other cellular processes.
What is the connecting link between hexose monophosphate shunt and lipid synthesis?
The connecting link between the hexose monophosphate shunt (pentose phosphate pathway) and lipid synthesis is the generation of NADPH. NADPH produced during the pentose phosphate pathway is utilized as a reducing equivalent in the fatty acid synthesis pathway. This NADPH provides the necessary reducing power for the synthesis of fatty acids from acetyl-CoA.
Which of the following represents a difference between extrinsic and intrinsic blood clotting pathways?
An important difference between the extrinsic and intrinsic blood clotting pathways is the way they are initiated. The extrinsic pathway is activated by external trauma that exposes tissue factor, while the intrinsic pathway is triggered by factors within the bloodstream, such as collagen or platelets. Additionally, the extrinsic pathway is faster and primarily involved in the initial response to injury, while the intrinsic pathway is more complex and amplifies the clotting process.
In a cell what serves as a pathway for the transport of materials throughout the cell also associated with synthesis and storage?
The endoplasmic reticulum (ER) serves as a pathway for the transport of materials throughout the cell. It is also involved in protein synthesis and lipid metabolism. The smooth ER is involved in lipid synthesis and detoxification, while the rough ER is involved in protein synthesis.
What is the difference between a direct or an indirect pathway for bioaccumulation?
In a direct pathway for bioaccumulation, organisms take in contaminants directly from the environment through processes like ingestion or absorption. In an indirect pathway, organisms accumulate contaminants by consuming other organisms that have already bioaccumulated the contaminants.
What is HMP pathway?
The HMP (Hexose Monophosphate) pathway is a metabolic pathway that generates NADPH and ribose-5-phosphate. It is important for generating reducing power (NADPH) and nucleotide precursors for processes like fatty acid synthesis and nucleotide synthesis. This pathway is also known as the pentose phosphate pathway.

What is the difference between series and parralal circuit?
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.

This NADPH provides the necessary reducing power for the synthesis of fatty acids from acetyl-CoA.
What is the end product of the pentose phosphate pathway?
The end product of the pentose phosphate pathway is nicotinamide adenine dinucleotide phosphate (NADPH) and ribose-5-phosphate. NADPH is an important reducing agent used in biosynthetic processes and ribose-5-phosphate is a precursor for nucleotide synthesis.
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.

What is the major difference between sinus and fistula?
A fistula is an abnormal pathway between 2 anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
