ETC

Question 1

Purpose of ETC

Answer 1

Pulling out hydrogen ions to create proton gradient to fuel complexes 3/4/5 to produce ATP

Question 2

Malate shuttle location

Answer 2

Kidney, liver, heart

Question 3

Glycerol-3-phosphate shuttle location

Answer 3

Brain, skeletal muscle

Question 4

Gluconeogenesis rate limiting step 1

Answer 4

Conversion of glucose to glucose-6-phosphate by GLUCOSE-6-PHOSPHATASE

Question 5

Gluconeogenesis rate limiting step 2

Answer 5

Conversion of fructose-6-phosphate to fructose 1,6-biphosphonate by fructose 1,6-biphosphatase

Question 6

Gluconeogenesis rate limiting step 3

Answer 6

Conversion of oxaloacetate to phosphoenolpyruvate by PHOSPHOPHENOLPYRUVATE CARBOXYKINASE

Question 7

Fructose metabolism rate limiting step

Answer 7

Aldolase B (deficiency results in fructose intolerance, buildup of fructose 1,6-phosphate in the liver)

Question 8

Galactose metabolism rate limiting step

Answer 8

Galactokinase (blocks ATP to ADP) or galactose-1-phosphate uridyltransferase (blocks galactose-1-P to glucose p-1-P)
