NST 10 ACTUAL TEST PAPER COMPLETE
QUESTIONS AND ANSWERS FULL
SOLUTION
●● Catabolism
Answer: breaks down into smaller units, releases energy
●● Oxidation
Answer: Loss electrons
●● Reduction
Answer: Gain electrons
●● Where do the citric acid cycle and electron transport chain take
place?
Answer: mitochondria
●● Where does Glycolysis take place?
Answer: cytoplasm
●● How do we measure the calorie content of food?
Answer: bomb calorimetry
,●● How is Basal Metabolic rate measured?
Answer: direct calorimetry, indirect calorimetry, stable isotope methods.
●● What fraction of the body fluids is intracellular and extracellular?
Answer: 1/3 is extracellular
2/3 intracellular
●● Interstitial body fluid
Answer: bathes and surrounds the tissue cells
●● Intravascular
Answer: Blood, mixtures of blood cells, colloid, solutes
●● What is body fluid composed of?
Answer: Water and Minerals (Na+, K+, Cl-)
●● What signals dehydration?
Answer: Low blood volume and high solute concentration
●● Antidiuretic hormone (ADH)
Answer: promotes reabsorption of water only
, ●● Aldosterone
Answer: promotes salt retention and water follows, increases blood
volume, reabsorbs both
