A: Striated

Q: Why is ATP important in muscle contraction?
- It provides energy for muscle relaxation
- It allows for the attachment of actin to myosin
- It provides energy for myosin heads to detach and reattach
- It helps in the formation of muscle fibers
A: It provides energy for myosin heads to detach and reattach

Q: Which of the following muscles is primarily responsible for flexing the elbow?

- Quadriceps femoris
- Biceps brachii
- Hamstrings
A: Biceps brachii

Q: What is the role of calcium ions in muscle contraction?
- They help muscles relax
- They bind to troponin, exposing binding sites on actin
- They provide energy for ATP production
- They strengthen muscle fibers
A: They bind to troponin, exposing binding sites on actin

Q: Which muscle is located in the chest and responsible for pushing movements?
- Deltoids
- Pectoralis major
- Latissimus dorsi
- Biceps brachii
A: Pectoralis major

Q: How do cardiac muscle contractions differ from skeletal muscle contractions?
- Cardiac muscle contractions are voluntary
- Cardiac muscle contractions are involuntary and rhythmic
- Cardiac muscle contractions are faster
- Cardiac muscle contractions require more ATP
A: Cardiac muscle contractions are involuntary and rhythmic

Q: Which muscle group is primarily involved in knee extension?
- Hamstrings
- Quadriceps
- Gluteus maximus
- Gastrocnemius
A: Quadriceps

Q: What is the sliding filament theory?
- A theory explaining how muscles relax

- Biceps brachii
- Triceps brachii
- Pectoralis major
- Deltoids
A: Triceps brachii

Q: How does smooth muscle tissue facilitate digestion?
- By contracting voluntarily
- By maintaining posture
