The Ubiquitin/Proteasome System (UPS) is a
highly regulated mechanism of intracellular protein degradation and turnover
. Through the concerted actions of a series of enzymes, proteins are marked for proteasomal degradation by being linked to the polypeptide co-factor, ubiquitin.
What are the packages of the cell?
Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called
the Golgi apparatus
. The Golgi apparatus is a set of flattened, membrane-bound sacs that serve as the packaging and distribution center of the cell.
Which part of the cell is like the ups of the cell?
The Golgi Apparatus
is like a UPS truck because the golgi apparatus packages and ships proteins where they are needed like a UPS truck packages and ships items where they are needed.
What is the shipping department of a cell?
The Golgi apparatus
is often considered the distribution and shipping department for the cell’s chemical products. It modifies proteins and lipids (fats) that have been built in the endoplasmic reticulum and prepares them for export outside of the cell or for transport to other locations in the cell.
What is lysosome function?
Abstract. Lysosomes are membrane-bound organelles with roles in processes involved in
degrading and recycling cellular waste, cellular signalling and energy metabolism
.
Is the powerhouse of cell?
The mitochondria
, often labeled the powerhouse of the cell, are the organelle responsible for energy production within the cell. Playing an important role in cellular respiration, the mitochondria are the main location for ATP production.
How a cell works like a factory?
A cell can be thought of as a “factory,” with different departments each performing specialized tasks. A cell’s plasma membrane regulates what enters or leaves the cell. … The cytoplasm is similar to the factory floor where most of the
products
are assembled, finished, and shipped.
What is the powerhouse of the cell?
Mitochondria
, the powerhouse of the cell, convert sustenance into energy, fueling the cell’s activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells.
Which type of transport is osmosis?
Osmosis is a type of
simple diffusion
in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.
What cell makes ribosomes?
Eukaryote ribosomes are produced and assembled in
the nucleolus
. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).
What is a cell similar to?
A cell is
like a car
. The nucleus of a cell would be like the driver of a car, they control the cell/car. Cell membrane is like the doors on a car. They regulate what goes in/out.
Why is a cell like a factory?
Cells are
similar to factories in that they are both systems, which integrate and work together
. Major cell parts function just like the structures and people who work together in a factory. … Cells have a cytoplasm, which contains the organelles of the cell and serves as a floor space would be for a factory.
What can I compare a cell to?
- The rough endoplasmic reticulum of the cell is like the hallways in a house because they transport people throughout the home like the rough ER transports materials throughout the cell.
- Sources:
- The mitochondria of the cell are like the fuse box of a house. …
- Ribosomes are like an oven.
Where is lysosome found?
Lysosome, subcellular organelle that is found in
nearly all types of eukaryotic cells (cells with a clearly defined nucleus)
and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.
What is a lysosome simple definition?
A lysosome is
a membrane-bound cell organelle that contains digestive enzymes
. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
