PAPER 2026 COMPLETE QUESTIONS AND
SOLUTIONS GRADED A+
◉ Define homeostasis? Answer: Maintenance of a constant internal
temperature in the body
◉ What is metabolism? Answer: Biochemical processes within a
living organism that sustain life
◉ List and define the two phases of metabolism Answer: Phase1:
Catabolism (break-down)
Phase2: Anabolism (Build-up)
◉ What is BMR and how does it relate to a humans metabolic set
point? Answer: The lowest amount of energy required to maintain
the body's life function while in a resting state. This is Usually
expressed in calories per hour per square meter of the surface of the
body.
◉ How do a kilocalorie and a calorie relate? Answer: There are 1000
calories in a kilocalorie
,◉ Define the thermic effect? Answer: The heat liberated from food
as a measure of its energy content.
◉ Metabolic adaptations to endurance training Answer: - Increased
muscle glycogen storage capacity
- Increased muscle mitochondrial density
- Increased resting adenosine triphosphate(ATP) content in muscles
- Increased resting Creatine phosphate(CP) content in muscles
- Increased resting creatine content in muscles
◉ Anaerobic training adaptations Answer: - Increased size and
number of fast-twitch muscle fibers
- Increased tolerance to higher levels of blood lactate
- Increases in enzymes that are involved in the anaerobic stage of
glucose breakdown (known as glycolysis)
- Increased resting levels of ATP CP creatine, and glycogen content in
muscles.
- Increased levels of growth hormone and testosterone after short
bouts (45 to 75 min) of high-intensity weight training
◉ ATP Answer: A compound know as Adenosine Triphosphate
whose breakdown leads to energy release used for muscle
contraction

◉ Describe the respiratory system and its function Answer: The
organ system responsible for oxygen intake and carbon dioxide
excretion.
◉ Explain the "training effect and how it influences the lungs
throughout exercise Answer: An increase in activity results in an
increased oxygen demand, which in turn causes the lungs to work
more.
