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.
B) Apoptosis (main type of programmed cell death). This is the type of cell death that occurs deliberately under physiological and genetic control, which involves a single cell or a small group of cells in a tissue.Unlike necrosis, in apoptosis, other cells in the tissue are not affected and functioning normally.he uncontrolled cell death that occurs as a response to lethal injury leading to a severe physical damage in the cell as well as the tissue containing it. This is usually not an energy-dependent active process but a result of a sudden abnormal change in the microenvironment that destroys the function of the cell.
