Question 8

cori cycle - summary of reaction

pyruvate formed from the glycolytic pathway is converted to lactate via enzyme _____

it is then transported to the liver and is converted into glucose by the _____ after transport

Answer 8

lactate dehydrogenase; liver

Question 9

cori cycle activator

is the enzyme _____

Answer 9

lactate dehydrogenase

Question 10
