Understanding Cell Necrosis and Degradation

What are the main types of cell necrosis?

• Coagulative, liquefactive, caseous, fat, and fibrinoid necrosis.

• Hemorrhagic, ischemic, necrotic, and fibrotic necrosis.

• Apoptotic, necrotic, regenerative, and inflammatory necrosis.

• Granulomatous, necrotic, apoptotic, and proliferative necrosis.

Describe the mechanisms involved in cell degradation.

• Cell degradation is solely caused by inflammation.

• Cell degradation occurs through apoptosis, autophagy, and necrosis.

• Cell degradation only occurs during cell division.

• Cell degradation is a process that enhances cell growth.

How does apoptosis differ from necrosis?

• Apoptosis is a type of necrosis.

• Apoptosis occurs only in response to injury.

• Apoptosis is programmed cell death; necrosis is uncontrolled cell death.

• Necrosis is a controlled process of cell death.

What role does inflammation play in necrotic cell death?

• Inflammation has no effect on necrotic cell death.

• Inflammation solely protects against necrotic cell death.

• Inflammation reduces necrotic cell death by healing tissue.

• Inflammation exacerbates necrotic cell death by promoting immune response and tissue damage.

Can you explain the significance of apoptosis in tissue homeostasis?

• Apoptosis is unrelated to cell health and disease prevention.

• Apoptosis is significant for tissue homeostasis as it removes damaged or unnecessary cells, regulates cell numbers, and prevents diseases.

• Apoptosis increases cell numbers in tissues.

• Apoptosis only occurs during embryonic development.

Answer explanation

*A more compleMore complex, occurs in the mitochondria. Re qui

●Complex process

● Occurs in the mitocondria in the presence of O2

●Requires the heart, lungs and circulatory system to function efficiently

●supplies the body with 90% of its energy needs

● obtained from using large stores of glycogen in the body .

● This is then synthesized into ATP

● May also be obtained from breaking down carbohydrates, proteins and fats, requires more O2

● by product is CO2 + H2O. Non toxic to the body, can be excreted .
