The definition of fermentation has evolved over the years. [1] The most modern definition is catabolism, where organic compounds are both the electron donor and acceptor. [1] [2] A common electron donor is glucose, and pyruvate is a common electron acceptor.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
A series of biochemical switches control transitions between and within the various phases of the cell cycle.The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases.
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Several yeasts, in particular S. cerevisiae and S. pombe, have been widely used in genetics and cell biology, largely because they are simple eukaryotic cells, serving as a model for all eukaryotes, including humans, for the study of fundamental cellular processes such as the cell cycle, DNA replication, recombination, cell division, and ...
The cell cycle is a sequence of activities in which cell organelles are duplicated and subsequently separated into daughter cells with precision. There are major events that happen during a cell cycle. The processes that happen in the cell cycle include cell development, replication and segregation of chromosomes.
In oncology, the Warburg effect (/ ˈ v ɑːr b ʊər ɡ /) is the observation that most cancers use aerobic glycolysis and lactic acid fermentation for energy generation rather than the mechanisms used by non-cancerous cells. [1]
S. cerevisiae forms a bud which can grow throughout its cell cycle and later leaves its mother cell when mitosis has completed. [ 30 ] S. cerevisiae is relevant to cell cycle studies because it divides asymmetrically by using a polarized cell to make two daughters with different fates and sizes.
