BSNC 3000 - Module 11: Cellular
Regulation & Cancer Exam Questions &
Answers (Grade A+)
What is cellular regulation? -
correct answer ✅all functions carried out within a cell to maintain
homeostasis
What are the functions of cellular regulation? -
correct answer ✅- responses to extracellular signals
- internal processes growth, proliferation, differentiation
What is the normal cell regulation process? -
correct answer ✅cells grow and proliferate when needed
When does growth and proliferation normally occur? -
correct answer ✅- during development of fetus
- tissue healing
- sperm cells
- RBCs replenishment
What is cell adaptation? -
correct answer ✅regulated changes in growth and proliferation
,BSNC 3000 - Module 11: Cellular
Regulation & Cancer Exam Questions &
Answers (Grade A+)
What are examples of cell adaptation? -
correct answer ✅- hypertrophy
- hyperplasia
- atrophy
- anaplasia
- dysplasia
What is neoplasia? -
correct answer ✅permanent uncontrolled cell growth and
proliferation
What is the size of a cell population determined by? -
correct answer ✅balance of cell proliferation and cell
death/apoptosis
What is cell proliferation? -
correct answer ✅process of increasing cell numbers by mitotic
division
, BSNC 3000 - Module 11: Cellular
Regulation & Cancer Exam Questions &
Answers (Grade A+)
What is cell death/apoptosis? -
correct answer ✅programmed death of aged, damaged, or excess
cells
Why do cells divide? -
correct answer ✅- stimulation by growth promoting factors
- availability of open space in a tissue
What does cell proliferation require? -
correct answer ✅adequate supply of O2 and nutrients
What is the process of growth promoting factors? -
correct answer ✅- growth factors bind to a specific receptor
- an intracellular signalling pathway conveys the message to the
nucleus
- transcription factors bind to DNA = proteins necessary for DNA
replication and mitosis are synthesized
- cell progresses through cell cycle
