What packages molecules for various destinations?
The finished new proteins end up in the trans Golgi network, which packages them in transport vesicles and dispatches them to their specific destinations in the cell.
What are the advantages of an electron microscope over a light microscope for what tasks would it be preferable to use a light microscope?
What are the advantages of an electron microscope? for what tasks would it be preferable to use a light microscope? An electron microscope has greater resolving power and is capable of greater magnification than a light microscope, enabling it to reveal finer details than a light microscope.
What transports proteins from rough endoplasmic reticulum to the Golgi apparatus?
Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus. Lysosomes are vesicles that are formed by the Golgi apparatus.
What part of the cell carries secretions for export from cell?
Endoplasmic reticulum is found inside your cells.
What cell structure sorts packages proteins?
Once proteins are created, they move to another organelle, the Golgi (GAWL jee) apparatus. The Golgi apparatus modifies, sorts, and packs the proteins into sacs called vesicles. The vesicles fuse with the cell’s plasma membrane.
What packages are useful materials?
Explanation: Golgi apparatus modifies & packs the protiens & lipids within the cell. And after that endoplasmic reticulum generates those materials with the help of vesicles.
What Cannot be seen with a light microscope?
With light microscopy, one cannot visualize directly structures such as cell membranes, ribosomes, filaments, and small granules and vesicles.
What are the advantages and disadvantages of a light microscope?
Advantage: Light microscopes have high magnification. Electron microscopes are helpful in viewing surface details of a specimen. Disadvantage: Light microscopes can be used only in the presence of light and have lower resolution.
What types of proteins are synthesized by the rough ER?
Rough ER contains two integral membrane proteins, ribophorins I and II, that have molecular masses of 65 kDa and 63 kDa, respectively. These proteins remain attached to ribosomes when the ER membrane is dissolved with detergent and they can be crosslinked to ribosomes by chemical reagents.
What is the sticky layer that holds animal cells together?
The middle lamella is a layer of sticky material, also containing pectin, which serves as “glue” to hold adjacent cells together.
What structure in the cell transports proteins?
The Endoplasmic Reticulum
The Endoplasmic Reticulum or ER is an extensive system of internal membranes that move proteins and other substances through the cell. The part of the ER with attached ribosomes is called the rough ER. The rough ER helps transport proteins that are made by the attached ribosomes. New proteins enter the ER.
What are the major cellular structures?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.
