What is the relationship of NADP and NADPH?
Lynna [10]
NADPH is the reduced form of NADP+. This simply means that NADPH has an extra hydrogen ion. NADPH is formed when upon the reduction of NADP+ . NADP stands for nicotine amide dinucleotide phosphate. It is a coenzyme that is involved in a wide range of anabolic reactions. During the synthesis of carbohydrates in plants, NADPH acts as a reducing agent, likewise in the synthesis of nucleic acids and lipids. As a reduced compound, NADPH becomes a molecule with high energy thus being especially useful in driving the Calvin cycle.

What was the purpose of adding methotrexate to the cells expressing a genetically-engineered Dihydrofolate Reductase enzyme in t
ira [324]

Answer:

Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.

Explanation:

Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
