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.
Programmed cell death. Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. PCD is carried out in a regulated process, which usually confers advantage during an organism's life-cycle.
