Glucagon

This is a peptide products in pancreatic α-cells, secreted by fasting, low BGL, stress, and exercises. Raises BGL levels

Adrenaline

This is a tyrosine-synthesised hormone and neurotransmitter, released due to perceived stress and primes the body for the fight or flight response

Mutase

This is an enzyme that isomerases glucose-1-phosphate into glucose-6-phosphate for use in glycolysis in muscle

Glucose-6-phosphatase

This is an enzyme in the liver that cleaves phosphate from glucose-6-phosphate for use in tissues

Aerobic exercise 

This is exercise that uses oxidative pathways to support prolonged and low-intensity exercise

Anaerobic exercise

This is exercise that uses non-oxidative pathways to support short and high-intensity exercise

Lactate

This a pyruvate breakdown product from anaerobic respiration, causes muscle pain and fatigue

Phosphocreatine

This is an on-site fuel in muscles that provides an energy buffer, around 20 μmol/g providing ~10 seconds worth of ATP
