What are the characteristics of the different ways Muscle cells can produce ATP

Groups:

(a) Phosphorylation of Creatine Phosphate

,

(b) Anaerobic Fermentation

,

(c) Aerobic Respiration

• Can produce ATP for hours

• Produces ATP for a very short period of time

• Produces large amounts of ATP

• Results in Lactic Acid buildup in muscle tissue

• Produces ATP when not enough oxygen is present
