    About the Lecture

    The lecture Pyrmidine de novo Metabolism: ATCase Reaction by Kevin Ahern, PhD is from the course Purine and Pyrimidine Metabolism.


    Included Quiz Questions

    1. ATCase
    2. PRPP synthetase.
    3. PRPP amidotransferase
    4. IMP dehydrogenase
    5. Adenylosuccinate synthetase
    1. ATP and aspartate
    2. CTP and aspartate
    3. GTP and aspartate
    4. UTP and aspartate
    5. TTP and aspartate
    1. The higher concentrations of CTP inhibits the ATCase enzyme via feedback mechanism and hence stops further synthesis of pyrimidine nucleotides
    2. The higher concentrations of CTP inhibits the ATCase enzyme via feedback mechanism, and hence stops further synthesis of purine nucleotides
    3. The higher concentrations of CTP activates the ATCase enzyme, and hence synthesis of pyrimidine nucleotides gets enhanced
    4. The higher concentrations of CTP activates the ATCase enzyme, and hence synthesis of purine nucleotides gets enhanced
    5. The higher concentrations of CTP activates the ATCase enzyme, and hence synthesis of aspartate gets enhanced
    1. None of the answers are true
    2. All of the answers are true
    3. It is activated by CTP and ATP
    4. It is inhibited by aspartate
    5. It is inhibited by ATP

    By Orel G. on 24. June 2017 for Pyrmidine de novo Metabolism: ATCase Reaction

    It was very clear and explained well- the subject itself is usually hard to explain
