Homework Answers
Answer
30. Option A) Creatine phosphate
- A phosphorylated molecule of creatine serves a energy storage in the muscle cell.
- This component is very important to provide rapid energy during intense muscle contraction.
31. Option B) Myoglobin
- Like blood contains hemoglobin, muscle cells contain myoglobin pigment yo store oxygen.
- Myoglobin binds to iron as well as oxygen molecules.
- The muscles that are high in myoglobin content are red in color.

Question 44 (4 points) In the process of generating ATP, lactic acid buildup in the muscle can occur causing muscle soreness. The pathway that causes lactic acid buildup is called: Electron transport Creatine phosphate phosphorylation Aerobic cellular respiration Anaerobic cellular respiration

The excitation, contraction, and relaxation of skeletal muscle
require the use of ATP. Because only limited stores of ATP are
immediately available in muscle tissue, ATP must be continually
supplied if contractile activity is to continue.
Depending on the type of movement or exercise, one or more
pathways can be used to provide the most efficient way of supplying
the ATP.

EXERCISE 4: Muscle pH 28. If you recall, there are three different metabolic pathways driving ATP production in skeletal muscle that are active at all times. However, the predominant pathway at any given time depends on the speed of the pathway and energy demand of the muscle. a. Which metabolic pathway predominates once creatine phosphate is depleted and before oxidative phosphorylation can occur ? Where does this occur within the cell? b. What is pyruvate converted to when oxygen delivery...
