CARDS B1 ( mitochondria, cell wal, ribosome...) Flashcards
Mitochondria
they are complex organelles
performs cellular respiration (cell energy)
produce of the most energy of the cells, through the process called cellular respiration
Centriole
perform out cell division participates in the formation of cilia and fragellos. Has structures proteins how, aquitin, keratin,
Nucle/core
Storage of genetic information
DNA duplication
Synthesis and processing of messenger, transporter, and ribosomal RNA
Ribosome
performs protein synthesis in all cell types
Granular endoplasmic reticulum
stores proteins that cells use, common in cell types that are involved in intense protein synthesis, such as pancreatic cells and plasma cells. have ribosome
Non-graulous endoplasmic reticulum
doesnt have ribosome, participe in muscle contraction and synthesis of some phospholipid hormones. These organelles are found in striated muscle cells and act by accumulating and releasing calcium ions to ensure the contraction process
Lysosome
acts in intracellular digestion, ensuring the degradation of materials captured by the cell, as well as the recycling of some cellular components (autophagy).
Peroxisome
helps detoxify molecules in the bloodstream and breaks down fatty acids.
Golgi complex
modifys proteins and lipids from the endoplasmic reticulum. transports and addresses substances
Cytoplasm
It is composed of hyaloplasm and the differentiated cytoplasm that encompasses organelles and inclusions. in the hyaloplasm is where important reactions take place, such as the binding between transfer RNAs and amino acids
1-Prokaryotic cell
2-where is prokariotic cell found?
1-They lack a nucleus and their genetic material is dispersed in the cytoplasm
2- its found in bacteria and arkea
Prokariotic cell, where is found?
doesnt have nucleus, its found in animals plants, algae…
Cell membrane
its a structure that delimits the citoplasme, separating the intracellular environment from the extracellular environment. It also does the Recognition of foreign substances
Cell membrane composition
it has a lipoprotein composition. the main lipids present are the phospholipds, whose head is hydrophilic ( has an affinity for water) because it is formed by glycerol, phosphate and apolar nitrogenous molecule, linked to a hydrophobic non-polar tail (with water repulsion) formad by fatty acids
Plasma membrane specialties
Microvilli: these are folds in the plasma membrane on the surface of intestinal, that increase the absorption of nutrients.
Desmosomes: they are protein plaques attached to protein the ads that stick on cell to another, make adhesion, very present in epithelial tissue.
Interdigitations: very common in muscle cells, they serve to unite one cell to another and exchange substances.
