Hace 5 días · Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.
- A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of...
- Cell theory states that the cell is the fundamental structural and functional unit of living matter. In 1839 German physiologist Theodor Schwann an...
- The cell membrane surrounds every living cell and delimits the cell from the surrounding environment. It serves as a barrier to keep the contents o...
Hace 3 días · In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth. Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes.
Hace 1 día · Eukaryotes have a life cycle that involves sexual reproduction, alternating between a haploid phase, where only one copy of each chromosome is present in each cell, and a diploid phase, with two copies of each chromosome in each cell.

Hace 18 horas · Abstract. Cellular metabolism comprises a complex network of biochemical anabolic and catabolic processes that fuel the growth and survival of living organisms. The enzyme malate dehydrogenase (MDH) is most known for its role in oxidizing malate to oxaloacetate (OAA) in the last step of the tricarboxylic acid (TCA) cycle, but it also participates in the malate-aspartate shuttle in the ...
