WACE Physical Education Studies ATAR Practice Questions - WACE ATAR Physical Education Studies Units 3 & 4 (SCSA Year 12 Assessment) Exam - WACE Physical Education Studies ATAR Practice Questions - WACE ATAR Physical Education Studies Units 3 & 4 (SCSA Year 12 Assessment) Exam

Question 1

Which energy system resynthesizes ATP at the fastest rate to power high-intensity explosive movements lasting up to 10 seconds?

Anaerobic glycolysis (Lactic Acid) system Aerobic energy system Beta-oxidation pathway ATP-PC (Phosphocreatine) system

Correct Answer:

ATP-PC (Phosphocreatine) system

Question 2

What primary metabolic by-product accumulates during high-intensity exercise powered by anaerobic glycolysis, leading to muscular fatigue and acidosis?

Carbon dioxide Hydrogen ions (H+) Creatine kinase Acetyl-CoA

Correct Answer:

Hydrogen ions (H+)

Question 3

Which substrate yields the greatest total number of ATP molecules per molecule oxidized during prolonged submaximal aerobic exercise?

Blood glucose Muscle glycogen Free fatty acids (Triglycerides) Phosphocreatine

Correct Answer:

Free fatty acids (Triglycerides)

Question 4

During a maximal 400m track sprint lasting approximately 50 seconds, which statement best describes the interplay of energy systems?

The ATP-PC system provides 100% of energy for 10s, followed exclusively by anaerobic glycolysis until 45s. All three energy systems contribute from the onset, but anaerobic glycolysis becomes the dominant provider after 5–10 seconds. The aerobic system is inactive for the first 30 seconds until heart rate reaches maximum. Anaerobic glycolysis is the sole energy contributor throughout the entire 50-second race.

Correct Answer:

All three energy systems contribute from the onset, but anaerobic glycolysis becomes the dominant provider after 5–10 seconds.

Question 5

What is cardiac output (Q), and how is it calculated?

The volume of blood ejected from the left ventricle per beat ($Q = SV / HR$). The total volume of blood in the circulatory system ($Q = EDV - ESV$). The rate of oxygen extraction by working skeletal muscles ($Q = atext{-}vtext{O}_2 text{ diff}$). The volume of blood pumped by the heart per minute ($Q = HR times SV$).

Correct Answer:

The volume of blood pumped by the heart per minute ($Q = HR times SV$).
