Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis : regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes). [2]
Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
Phagocytosis is the process in which a cell engulfs a particle, digests it, and expels the waste products. Process of phagocytosis: 1. A particle is ingested by a phagocyte after antigens are recognized which results in the formation of a phagosome. 2. The fusion of lysosomes with the phagosome creates a phagolysosome. 3.
In molecular biology and biochemistry, processivity is an enzyme's ability to catalyze "consecutive reactions without releasing its substrate". [1]For example, processivity is the average number of nucleotides added by a polymerase enzyme, such as DNA polymerase, per association event with the template strand.
Lysosomes are structures that use enzymes to break down substances through phagocytosis, a process that comprises endocytosis and exocytosis. In the mitochondria, metabolic processes such as cellular respiration occur. The cytoskeleton is made of fibers that support the structure of the cell and help the cell move. [2]
In biology, a mechanism is a system of causally interacting parts and processes that produce one or more effects. [1] Phenomena can be explained by describing their mechanisms. For example, natural selection is a mechanism of evolution ; other mechanisms of evolution include genetic drift , mutation , and gene flow .
Process costing, a cost allocation procedure of managerial accounting Process management (project management) , a systematic series of activities directed towards planning, monitoring the performance and causing an end result in engineering activities, business process, manufacturing processes or project management
