Question 18

Step 10 of gluconeogenesis

Answer 18

Glucose 6- phosphatase

Question 19

The four different enzymes in gluconeogenesis

Answer 19

Pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6 - phosphatase, glucose 6-phosphatase

Question 20

Net reaction with pyruvate carboxylase

Answer 20

Pyruvate + ATP + HCO3- = oxaloacetate + ADP + Pi

Question 21

Net reaction of phosphoenolpyruvate carboxykinase

Answer 21

Oxaloacetate + gtp → phosphoenolpyruvate + GDP + pi

Question 22

Net reaction of fructose 1,6- bisphosphatase

Answer 22

Fructose1,6-bisphosphate + H2O → fructose 6-phosphate + pi

Question 23

Net reaction for glucose 6-phosphatase

Answer 23

Glucose 6-phosphate+ H2O → glucose + pi
