IB Sports Science Exam Questions with Correct Answers| Latest Update Graded A+
Glycogenesis Storage of Glucose in muscles and Liver
Glycogenolysis Breakdown of storage Carbohydrate
Gluconeogensis Conversion of Lactate to Glucose, Occurs in the Liver
Glycolysis Breakdown of Glucose to Pyruvate or Lactate
Lipolysis Breakdown of Fats for Aerobic Respiration
Insulin (STORAGE) Secreted by Pancreas
Lowers blood glucose
Inhibits gluconeogenesis and lipolysis
Promotes glycogenesis
Glucagon (RELEASE) Increases blood sugar
Stimulates glycogenolysis
Activated lipolysis of triglycerides
Energy Systems (Diagram on Laptop) Creatine Phosphorylation: Cytoplasm, CP, No Oxygen,
1 ATP, 20 seconds
Anaerobic Glycolysis: Cytoplasm, Glucose, No Oxygen, Pyruvate Lactate 2 Atp, 40-90 seconds
, Aerobic Respiration: Mitochondria, Pyruvate and Lactate, Oxygen, 32 ATP, hours
Excess Post Exercise Oxygen Consumption Oxygen Deficit: Lack of O2 needed to fuel activity
Oxygen Debt: During recovery, increase rate of O2 consumption
Topic 4: Movement Analysis --
Sliding Filament Theory 1) Release of Ach
2) Ach triggers release of Calcium from sarcoplasmic reticulum
3) Calcium binds to troponin
4) Myosin heads attach to actin sites
5) Myosin pulls on actin with ATP
6) Myosin head releases actin when ATP is formed
Types of Muscle Contraction Isotonic:
--Concentric: Muscle shortens during contraction
--Eccentric: Muscle is lengthening while contracting
Isometric: Muscle generates force without changing length
Isokinetic: Muscle contracts and shortens at a constant rate of speed
Reciprocal Inhabition Agonist: Causes movement
Antagonist: Works opposite to Agonist to return joint to original position
Types of Forces Vector: Magnitude and direction
