Bioenergetics (Lec 6)

Question 1

Glycogen Phosphorylase

Answer 1

Aids in the transformation of Glycogen -> Glucose, activated by ↑ ADP, Ca2+, Epinephrine, inhibited by ↑ ATP and Fatty Acids

Question 2

Hexokinase

Answer 2

Aids in transformation of blood Glucose -> glucose-6-phosphate, inhibited by glucose-6-phosphate and ↑ Fatty acids

Question 3

Phosphofructokinase (PFK)

Answer 3

Aids in transformation of glucose-6-phosphate -> fructose 1,6 biphosphate, activated by ↑ fructose 1,6 biphosphate, ADP and ↓CP, inhibited by ↑ H+, Citrate (Krebs cycle), ATP, Fatty acids

Question 4

Pyruvate Kinase

Answer 4

Activated by ↑ fructose 1,6 biphosphate, inhibited by ATP and Alanine

Question 5

Kreb’s Cycle

Answer 5

Known as Cytric Acid Cycle or Tricarboxylic acid cycle, complete oxidation of C, H, O, fats and sometimes proteins for use in Electron Transport Chain (chemiosmosis)
