you need carbohydrates to make ATP. Mitochondria needs oxygen to make ATP.
1. Hydrolysis of ATP releases energy required for muscular contraction
2. Adenosine triphosphate (ATP) binds to the myosin cross bridge
3. Factors that help with energy production
a. Creatine phosphate - AA attached to the phosphate (high energy bond to make ATP w/o going to mitochondria)
b. Myoglobin - binds oxygen, carries oxygen
c. Glycogen - liver/carbs makes glycogen & ATP
d. Anaerobic respiration - results in oxygen debt
e. Aerobic respiration - mitochondria
4. Oxygen debt - mitochondria (ATP) & myoglobin (ATP) are gone. skeletan muscles. fatigue = muscle cramps
ex. chickens don't fly, don't need oxygen, therefore, use myoglobin.
