Apoptosis Programmed Cell Death

The video explains apoptosis, a process of programmed cell death crucial for organismal health. It discusses how apoptosis prevents cancer by eliminating faulty cells and details the molecular mechanisms involved. The video explores apoptosis in C. elegans, highlighting key genes and proteins, and contrasts this with the more complex human system. It also covers the role of apoptosis in development and its implications in diseases like Alzheimer's and Parkinson's.

What is the primary function of apoptosis in an organism?

• To increase enzyme production

• To enhance DNA replication

• To eliminate faulty cells

• To promote cell growth

During apoptosis, what happens to the cellular components?

• They are preserved for future use

• They are fragmented and removed

• They are converted into energy

• They are transferred to other cells

Which organism is used as an example to explain genetic regulation of apoptosis?

• Mouse

• Zebrafish

• Fruit fly

• C. elegans

What role does the Ced-9 protein play in apoptosis?

• It promotes cell division

• It initiates DNA replication

• It acts as a brake to regulate apoptosis

• It enhances protein synthesis

How does cytochrome c function outside the mitochondrial matrix?

• As a DNA repair enzyme

• As a cell growth promoter

• As a protein synthesis inhibitor

• As an apoptotic factor

What is a potential outcome if apoptosis fails to occur due to genetic mutations?

• Increased cell differentiation

• Formation of tumors

• Improved organ function

• Enhanced immune response

Which diseases are associated with problems in the apoptosis mechanism?

• Diabetes and hypertension

• Arthritis and osteoporosis

• Alzheimer's and Parkinson's

• Asthma and allergies
