State the organelle used to transport proteins and lipids. Explain the function of mitochondria, ribosomes, and lysosomes. Where in the cell can one find ribosomes and what is the main biological function of the ribosome? (a) Describe the structure of the ribosome. (b) Describe its function...
each with increasing acidity. Cargo is first internalized into mildly acidic early endosomes, where the molecules are either recycled back to the cell surface or delivered to late endosomes. Late endosomes (~pH 5.5) mediate the de...
What organelles do lysosomes interact with?Lysosome:A lysosome is an organelle present in both animal and plant cells. They may contain many different enzymes that help with the digestion of cellular components and processing of biomolecules such as proteins, lipids, nucleic acids, and carbohydrates....
NCL-associated proteins (CLN1 to CLN14) differ in their function and their intracellular localization (see Table 1). NCL proteins have been localized mostly in lysosomes (CLN1, CLN2, CLN3, CLN5, CLN7, CLN10, CLN12 and CLN13) but also in the Endoplasmic Reticulum (ER) (CLN6 and CLN8...
5. The accumulation of “junk” within the cell. The junk in question is a collection of complex material that results from the cell’s breakdown of large molecules. Intracellular structures called lysosomes are the primary microchambers for such breakdown; the junk tends to collect in them, ca...
of HCMV, which originally granted the virus its name, is that of forming in the infected cell a voluminous intranuclear inclusion body and one or more intra-cytoplasmic inclusion bodies, the so-called "owl's eye" inclusions, made up of clusters of newly formed viruses and lyso...
This latter is crucial in order to avoid degradation of the cargo in lysosomes, and to enable the cargo to reach its extra-endosomal target and exert its biological activity. The favorable conditions for endosomal escape (e.g. the physico-chemical properties of the CPPs) are not yet known,...

Are proteins made in the cytoplasm or the ribosomes? What is the phagocyte in the process of phagocytosis? What allows an ion to move across a cell membrane? What are the organelles characterized by a double membrane? Describe the function of organelles, cells, tissues, and the organ system...
Proteins destined to be delivered to the extracellular space do not enter the trans-Golgi cisternae. a. True. b. False. Golgi apparatus Proteins received from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where ...
