Resource summary

Question Answer
Pyruvate Carboxylase- Requirements Biotin and Mg2+
Pyruvate Carboxylase- Pyruvate, ATP & HCO3 --> OAA, ADP & Pi
Pryruvate Carboxylase- Activators Acetyl CoA & Pyruvate
Pyruvate Carboxylase- Inhibitors Calcium, glutatmate & ATP
Increasing Pyruvate Carboxylase Activity- Short Term Increase enzyme activity through allostery
Increasing Pyruvate Carboxylase Activity- Long Term Make more Pyruvate Kinase
PEPCK- OAA + GTP PEP + GDP + CO2
PEPCK- Control No allosteric/covalent
PEPCK - Activation Glucagon, cAMP & Diabetes (switched off by insulin)
