Question

Match List I with List II.

List I	List II
A. Phosphagen system B. Anaerobic glycolytic system C. Aerobic system D. Immediate energy system	I. Major source of energy during the first 30 seconds II. The maximum capacity of the system is small III. Lactic acid is produced IV. The maximum capacity of the system is great

Choose the correct answer from the options given below:

• A. A-I, B-III, C-IV, D-II
• B. A-I, B-IV, C-III, D-II
• C. A-II, B-III, C-IV, D-I
• D. A-I, B-III, C-II, D-IV

Hint:

ATP-PC = instant but low capacity, Anaerobic = short + lactic acid, Aerobic = long duration + high capacity

Answer 1

The Correct Option is A

Concept:
Energy systems in the human body are classified based on oxygen requirement, duration, and energy capacity.

Step 1: Phosphagen system.

• Provides immediate energy
• Dominant in first 10–30 seconds of activity Thus: \[ A \rightarrow I \]

Step 2: Anaerobic glycolytic system.

• Breaks down glucose without oxygen
• Produces lactic acid as a by-product Thus: \[ B \rightarrow III \]

Step 3: Aerobic system.

• Uses oxygen for energy production
• Has large energy capacity for prolonged activities Thus: \[ C \rightarrow IV \]

Step 4: Immediate energy system.

• Refers to ATP-PC system
• Has very limited energy stores Thus: \[ D \rightarrow II \]

Step 5: Final mapping.
\[ A\!-\!I,\; B\!-\!III,\; C\!-\!IV,\; D\!-\!II \] \[ \boxed{\text{Correct answer = Option (1)}} \]
