Apoptosis refers to a programmed cell death; a biological process in which the body of an organism destroys its cells for different reasons. In reality, apoptosis and necrosis involve different mechanisms, and this implies they are different. In addition, the changes that occur in the process of cell death are differing in terms of morphology and chemical composition.
Evidence indicates that there are various factors that make cells commit suicide. In most cases, cells commit suicide due to imbalances between positive and negative signals that determine cell survival. Cells can consider committing suicide upon the recipient of negative signals.
This research will provide a comprehensive overview of apoptosis. It will discuss mechanisms of apoptosis and the factors involved in the process. It will also explain the association between apoptosis.

Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This chapter provides an overview of apoptosis, defining it as a programmed cell death that plays a crucial role in various biological processes, including development, aging, immune reactions, and disease responses. It highlights the complex nature of apoptosis, which is triggered by diverse stimuli and involves a cascade of events leading to cell demise.
- Distinguishing Apoptosis from Necrosis: This chapter contrasts apoptosis and necrosis, emphasizing that they are distinct cell death processes with different mechanisms and morphological changes. Necrosis is described as cell death due to injury, while apoptosis is characterized as a programmed suicide process.
- Factors Leading to Cell Suicide: This chapter explores the various factors that can trigger apoptosis. It emphasizes the role of imbalances between positive and negative signals in determining cell survival or death. The chapter discusses how the withdrawal of positive signals, such as growth factors, and the presence of negative signals, such as defective proteins and DNA damage, can initiate the apoptotic program.
Schlüsselwörter (Keywords)
This research focuses on the molecular mechanisms of apoptosis, examining the processes involved in programmed cell death, the differences between apoptosis and necrosis, and the factors that influence cell suicide, including positive and negative signals. Key concepts include cell survival, cell death pathways, DNA damage, growth factors, and the role of apoptosis in biological processes such as development, aging, and disease responses.
