Answer
  • Mitochondria
  • Ribosome
  • Nucleolus
  • Lysosome

Question 3

Question

Answer
  • Lysosomes
  • Peroxisomes
  • Ribosomes
  • Oxyhydrosomes

Question 4

Question
Which cell component is capable of cellular autodigestion when it is released during cell injury?
Answer
  • Ribosome
  • Golgi Complex
  • Smooth Endoplasmic Reticulum

Question 5

Question
What is the sequence of steps in the development of a digestive enzyme by the pancreas cells from the initial transcription to the release from the cell?
Answer
  • The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to the ribosome for synthesis, and is transported in a secretory vesicle to the cell membrane.
  • The enzyme is transcribed from RNA by DNA in the nucleus, proceeds to the lysosome for synthesis, and is transported in an encapsulated membrane to the cell membrane.
  • The enzyme is transcribed by the mitochondria in the nucleus, proceeds to the ribosome for synthesis, and is transported in a cytoskeleton to the cell membrane.
  • The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to the Golgi complex for synthesis, and is transported in a cytosol to the cell membrane.

Question 6

Question

Answer
  • G1
  • S
  • G2
  • M
