The pater familias, also written as paterfamilias (pl.: patres familias), [1] was the head of a Roman family. [2] The pater familias was the oldest living male in a household, and could legally exercise autocratic authority over his extended family. The term is Latin for "father of the family
Mitosis is generally preceded by the S phase of interphase, when the cell's DNA is replicated, and either occurs simultaneously with or is followed by cytokinesis, when the cytoplasm and plasma membrane are divided into two new daughter cells. Colloquially, the term "mitosis" is often used to refer to the entire process of cell division, not ...
Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
Maintenance respiration in plants refers to the amount of cellular respiration, measured by the carbon dioxide (CO 2) released or oxygen (O 2) consumed, during the generation of usable energy (mainly ATP, NADPH, and NADH) and metabolic intermediates used for (i) resynthesis of compounds that undergo renewal (turnover) in the normal process of metabolism (examples are enzymatic proteins ...
The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The bacterial cell wall is omitted, gram-positive bacterial cells do not have outer membrane. [6] The complete breakdown of glucose releasing its energy is called cellular respiration. The last steps of this process occur in mitochondria. The reduced molecules NADH and FADH 2 are generated by the Krebs cycle, glycolysis, and pyruvate processing.
