Question 1

why can’t skeletal muscle fibers metabolize lactate nor convert glucose via gluconeogenesis?

Answer 1

skeletal muscle cells lack GLUCOSE-6-PHOSPHATASE (G6Pase) enzyme necessary for gluconeogenesis

Question 2

where/when does ANAEROBIC glycolysis occur?

Answer 2

• erythrocytes (RBCs)
• leukocytes
• testes
• renal medullar cells
• type II fast-twitch muscle fibers in high-intensity, sustained, predominantly isometric exercise

Question 3

product of ANaerobic glycolysis

Answer 3

Lactate

(Ana exercises HIIT (high-intensity, isometric training) –> lactic acid)

Question 4

product of AEROBIC glycolysis

Answer 4

ACETYL-CoA

(enters the citric acid cycle)
