BTEC (Business and Technology Education Council) Sport Exam with Questions and Answers

BTEC (Business and Technology Education Council) Sport Exam with Questions and Answers Which structure is primarily responsible for the production of red and white blood cells in the human body during exercise and rest? a) Cartilage b) Bone marrow c) Tendons d) Ligaments Correct Answer b) Bone marrow Rationale Bone marrow, particularly red bone marrow, is responsible for hematopoiesis (production of blood cells). This is essential in sport because red blood cells transport oxygen to working muscles, while white blood cells support immune function and recovery. Cartilage provides cushioning, tendons attach muscle to bone, and ligaments connect bone to bone, none of which produce blood cells. During high-intensity exercise, which energy system is primarily used for a 100m sprint? a) Aerobic system b) ATP-PC (phosphocreatine) system c) Lactic acid system d) Oxidative system Correct Answer b) ATP-PC (phosphocreatine) system Rationale The ATP-PC system provides immediate energy for short, explosive activities lasting up to around 10 seconds, such as a 100m sprint. It does not require oxygen and rapidly replenishes ATP. The lactic acid system dominates slightly longer high-intensity efforts, while the aerobic system is dominant in endurance activities.
