A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
Answer:The cell cycle a. includes mitosis as an event.
Explanation:
The cell cycle consists of two stages:
interface and phase M (mitosis). In the first, the cell grows and doubles its DNA; It consists of phases G1, G2 and S. In phase M, the cell divides its already duplicated DNA and the cytoplasm divides into 2 (cytokinesis), forming 2 daughter cells. There is a G ° phase, where the cell is in a "vegetative" state, called "senescence." The cell cycle is regulated cyclin / CDK complexes, tumor suppressor genes (example: p53).
Hello.
TP is a molecule with adenosine and three phosphate groups attached to it (adenosine triphosphate). To get energy from ATP, one of the bonds between the phosphates is broken, yielding energy and the molecule ADP - adenosine diphosphate, a molecule with adenosine and two phosphates.
<span>In order to 'recharge' the molecule, a phosphate group is re-attached to ADP by ATP-synthase to yield ATP. In other words, energy is stored in the bonds between phosphates, and breaking the bond releases that energy.
