Study Notes
Cellular Processes
- Exocytosis is tightly regulated and energy-dependent.
- Endocytosis is characterized by the formation of membrane-bound vesicles.
Genetic Analysis
- DNA fragmentation shows a ladder pattern on agarose gel electrophoresis.
Cellular Stress
- Necrosis is characterized by the release of cell contents and an inflammatory response.
- Facilitated diffusion occurs at 4°C and is a passive process.
Cellular Response to Stress
- Heat shock proteins (HSPs) protect cells against protein denaturation during cell stress.
- Hypertrophy is NOT an example of a physiological adaptive response during cell stress.
- Hyperplasia is an increase in cell number, while hypertrophy is an increase in cell size.
Apoptosis
- Apoptosis targets damaged or unwanted cells for destruction.
Pathology
- Necrosis is triggered by ischemia, which can cause cell death.
- Pathology does NOT encompass the study of normal cellular function.
- R.Virchow proposed that disease arises from cellular changes.
- Cellular stresses can be caused by pathological stimuli, such as radiation or chemicals.
- Genetic and immune factors play a role in cellular adaptation to environmental stresses.
- Cancer is a pathological process that may result in abnormal cell growth.
- Healing can be stimulated in response to pathological stress through various mechanisms, such as protein synthesis.
- Cellular stresses can be caused by factors such as hypoxia, radiation, or chemicals.
