16 Questions
What is the normal physiologic process involved in cell proliferation?
Replacement of dead cells
What maintains the balance between cell proliferation and programmed cell death?
Apoptosis
What triggers cell division in healthy cells?
Growth factors
Which type of cells are constantly subject to signals that dictate their behavior?
Healthy cells
What are membrane-bound glycoprotein receptors responsible for?
Transmitting messages
What are growth factors responsible for stimulating?
Cell proliferation
Which of the following best describes the formation of cancer?
Cancer cells develop from normal cells that undergo uncontrolled growth and proliferation
What is the role of proto-oncogenes in cancer development?
They cause stimulatory proteins to be overactive, leading to excessive cell proliferation
What is the function of tumor suppressor genes?
They slow down cell division or tell cells to die at the right time
What is the significance of TP53 in relation to cancer?
It is an important tumor suppressor gene that helps keep cell division under control
How do viruses replicate?
Viruses use components of the cell to make copies of themselves
What is the structure of a virus particle?
Genetic material surrounded by a protective coat of protein called a capsid
What is the result of mutations in genes that regulate cell division?
Uncontrolled cell proliferation and cancer
How do cancer cells differ from normal cells?
Cancer cells undergo uncontrolled growth and proliferation
What causes cancer progression?
Aging, inherited mutations (Genetics), immune conditions
What characterizes metastasis in cancer?
Cancer cells break away and form new tumors in other parts of the body
Test your knowledge about the disturbance in cell physiology, specifically focusing on cancer development. Explore how healthy cells are constantly subject to signals that dictate cell behaviors such as division, differentiation, or programmed cell death.
