Sample Questions

Q1.Which statement best describes an amphibolic pathway?

  • AA pathway that only breaks down molecules (catabolic)
  • BA pathway that only synthesises molecules (anabolic)
  • CA pathway involved in both catabolism and anabolism
  • DA pathway that does not involve any energy changes

Q2.In animal muscle cells during vigorous exercise, pyruvic acid is reduced to:

  • AEthanol
  • BAcetyl CoA
  • CLactic acid
  • DCitric acid

Q3.Where is the electron transport system (ETS) located?

  • AIn the cytoplasm
  • BOn the inner mitochondrial membrane
  • CIn the mitochondrial matrix
  • DOn the outer mitochondrial membrane

Q4.For aerobic respiration, pyruvate must be transported from the __(1)__ to the __(2)__.

  • A(1) mitochondria, (2) cytoplasm
  • B(1) cytoplasm, (2) mitochondria
  • C(1) nucleus, (2) chloroplast
  • D(1) endoplasmic reticulum, (2) Golgi body

Q5.Which statement correctly distinguishes respiration from combustion?

  • ABoth release energy in a single step
  • BRespiration is a stepwise, enzyme-controlled process that traps energy in ATP, while combustion releases all energy as heat in one step
  • CCombustion occurs inside cells while respiration occurs outside
  • DRespiration does not require oxygen while combustion does
