Class 11 Biology — Chapter 17: Locomotion and Movement
60 practice questions · 20 Easy · 20 Medium · 20 Hard
Practise Class 11 Biology Chapter 17, "Locomotion and Movement", with 60 NCERT-aligned multiple-choice questions. The set is split into 20 Easy, 20 Medium and 20 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams and NEET UG.
"Locomotion and Movement" is one of the chapters where diagram-based recall, terminology and NCERT line-by-line accuracy really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Locomotion and Movement, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Biology mastery score. A few sample questions are shown below; sign in free to practise all 60.
Key concepts: Locomotion and Movement (Class 11 Biology)
This chapter covers types of movement, the structure of muscle and the sliding-filament mechanism of contraction, and the human skeletal system.
- Types of movement
- Amoeboid, ciliary and muscular movements; locomotion is movement that changes the body's location.
- Muscle structure
- Skeletal muscle fibres contain myofibrils with actin (thin) and myosin (thick) filaments arranged in sarcomeres.
- Sliding-filament theory
- Contraction occurs as actin filaments slide over myosin (cross-bridge cycle), driven by ATP and Ca²⁺.
- Skeletal system
- The axial and appendicular skeleton (206 bones in adults) supports the body and protects organs.
- Joints & disorders
- Joints (fibrous, cartilaginous, synovial) allow movement; disorders include arthritis, osteoporosis and gout.
💡 Exam tips for Locomotion and Movement
- In the sliding-filament theory the filaments don't shorten — they slide past each other, shortening the sarcomere.
- Ca²⁺ release and ATP are both required to trigger and power muscle contraction.
Sample questions
Voluntary muscles are:
Attached to bones; under conscious control.
Sliding filament theory: contraction is due to:
Cross-bridges and ATP power the slide.
Ca²⁺ binds ___ to initiate muscle contraction.
Ca²⁺-troponin shifts tropomyosin off binding sites.
