- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.
- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:
1. Damaged DNA
2. Increase of cytosolic calcium concentration
Explanation:
Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.
A group of cytoskeletal structures and related layer limited organelles found at the foremost finish of grown-up commit intracellular protozoan parasites in the phylum Apicomplexa. The apical complex is engaged with connection to and infiltration of the host cell and in parasite multiplication.
Apicomplexans
: Ciliates are pretty cool, but they're not the only group of alveolates out there. Next, we've got the apicomplexans. This group is characterized by an asymmetrical collection of alveoli at one end of the cell, which is called the apical complex.
the apical complex has shaped the way it is because it helps the cell latch onto and infects other cells.That's right, apicomplexans are parasitic. There are 4,000 known species of apicomplexans, all of them parasitic, and some of them pretty nasty.
PCOS stands for polycystic ovarian syndrome. PCOS is a condition in which the ovaries have multiple follicles that do not ovulate to release an egg due to hormonal disturbances. it is a common cause of infertility.
