Energy For Muscle Contraction

Question 1

Muscles require ATP for the following

Answer 1

1. Breakdown of creatine phosphate
2. Aerobic cellular respiration
3. Fermentation or anaerobic cellular respiration

Question 2

Creatine phosphate

Answer 2

High energy compound built when the muscle is resting

Generates ATP by breaking down creatine phosphate into creatine (ADP converted to ATP)

Question 3

Aerobic cellular respiration

Answer 3

• provides most of the muscle with ATP
• Myoglobin is synthesized in the muscle cells
• has a higher affinity for oxygen than hemoglobin

Question 4

Anaerobic respiration

Answer 4

Supplies ATP without oxygen due to the following reaction

Glucose - lactate ( ADP to ATP)

Question 5

Oxygen deficit

Answer 5

• when a muscle uses fermentation to supply its own energy needs
  -replenishing and oxygen deficit requires replenishing creatine phosphate and getting rid of lactate
