What is the role of transketolase and transaldolase in the pentose phosphate pathway?
Transketolase and transaldolase are enzymes that play key roles in the pentose phosphate pathway. Transketolase helps transfer two-carbon units between sugar molecules, while transaldolase helps rearrange sugar molecules to produce important intermediates for energy production and biosynthesis. These enzymes are essential for generating NADPH and ribose-5-phosphate, which are important for cell growth and maintenance.

What is another name for pentose pathway?
pentose phosphate pathway (also called phosphogluconate pathway, or hexose monophosphate shunt [HMP shunt])
What two important compounds are generated in Pentose Phosphate Pathway?
The two important compounds generated in the Pentose Phosphate Pathway are NADPH (reduced form of nicotinamide adenine dinucleotide phosphate) and ribose-5-phosphate. NADPH is crucial for reductive biosynthetic reactions and cellular antioxidative defenses, while ribose-5-phosphate is a precursor for nucleotide biosynthesis.
What tissue does the pentose phosphate pathway occur in?
1. In the cytoplasm, and is found to be most active in the liver 2. Mammary gland 3. Adrenal cortex. It is absent in skeletal muscle tissue. 4. in plants, most steps take place in plastids.
Why is glucose-6-phosphate important?
Glucose-6-phosphate is important because it serves as an intermediate in glycolysis, providing a starting point for further energy production in the form of ATP. It is also a precursor for the synthesis of nucleotides and amino acids, contributing to various metabolic pathways in the body. Additionally, glucose-6-phosphate plays a crucial role in the pentose phosphate pathway, which generates NADPH for cellular antioxidant defense and biosynthetic processes.
What is the principle of Glucose-6-phosphate dehydrogenase?
Glucose-6-phosphate dehydrogenase catalyzes the first step of the pentose phosphate pathway by converting glucose-6-phosphate to 6-phosphoglucono-δ-lactone, producing NADPH in the process. NADPH is essential for reductive biosynthesis and is a key antioxidant in protecting cells from oxidative stress. Deficiency in G6PD can lead to hemolytic anemia due to decreased antioxidant capacity in red blood cells.
What is the coenjyme of transketolase?
The coenzyme of transketolase is thiamine pyrophosphate (TPP). It plays a crucial role in the transfer of two-carbon units in the pentose phosphate pathway.
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.
