L7 - Glycolysis vs gluconeogenesis

Question 1

Hexokinase: what is it, what does it do, and how present is it throughout the genome of living organisms?

Answer 1

Enzyme that converts glucose into glucose-6-phosphate

Expressed in every known organism

Question 2

Glucose-6-phosphatase: what is it and what does it do?

Answer 2

Enzyme that converts G6P into glucose

Question 3

Glucose pathway to the citric acid cycle including enzymes

Answer 3

Glucose - G6P
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

G6P - F6P
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

F6P - F16BP
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

F16BP - PEP
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

PEP - Pyruvate
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

Pyruvate - Oxaloacetate
* Hexokinase (->)
* Glucose-6-phosphatase (<-)

Pyruvate - Acetyl CoA
* Hexokinase (->)
* Glucose-6-phosphatase (<-)
