Cellular respiration 1. Cellular respiration. Typical eukaryotic cell. Cellular respiration is the set of the. metabolic reactions and processes that take. place in the cells of organisms to convert. biochemical energy from nutrients into. adenosine triphosphate (ATP), and then. release waste products.[1] The reactions. involved in respiration are catabolic.
Programmed cell death. The programmed cell death is one of the two major kinds of cell death. The other is necrosis. Programmed cell death is a kind of cell death that is regulated by an intracellular program.1 The cell undergoes a natural process of death after completing a number of cell divisions. The cell ceases to carry out its functions and dies to be replaced by new ones.
Apoptosis and autophagy are both forms of programmed cell death, but necrosis is a non-physiological process that occurs as a result of infection or injury. Necrosis is the death of a cell caused by external factors such as trauma or infection and occurs in several different forms.poptosis is the process of programmed cell death (PCD) that may occur in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death.
