“Cancer is a disease which is caused due to the uncontrolled division of cell which leads to growth of tumor and reduced activity of immune system.” TYPES: – There are basically six types of cancers: A.] Carcinoma Cancer: This cancer […]
In pyrimidine synthesis, firstly the pyrimidine ring is formed and then ribose phosphate group is attached. This ribose phosphate group is donated by PRPP (phosphoribosyl-pyrophosphate). The major pyrimidine nucleotide involve: TMP, CMP and UMP. Precursors for the De-novo synthesis of […]
Catabolism of purine nucleotide The end product of catabolism of purine is uric acid. Mammals oxidize the uric acid to allantoin, which further get converted into urea and then ammonia. Reactions of catabolism of purine nucleotide Firstly the phosphate group […]
Purine and pyrimidine are dietary non-essential components. Dietary nucleic acid and nucleotides do not provide essential components for the synthesis of endogenous nucleic acids. In humans, the synthesis of nucleic acid is done by 2 methods: de-novo synthesis method and […]
The rate of enzymatic reactions depends on: Substrate concentration Enzyme concentration Effect of Ph Effect of temp Time Activators: it refers to the one that activates the enzymatic reaction. So activators are directly proportional to rate enzymatic reactions Inhibitors:– these […]
