The Golgi body
will produce and modify polysaccharides that will be secreted from the cell. The Golgi body is responsible for modifying and packaging…
What organelle makes proteins for secretion?
| Organelle Function | Rough Endoplasmic Reticulum (RER) Protein production; in particular for export out of the cell | Golgi apparatus Protein modification and export | Peroxisome Lipid Destruction; contains oxidative enzymes | Lysosome Protein destruction |
|---|
Which of the following organelles produces and modifies proteins that will be secreted?
The endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins.
The Golgi apparatus
modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.
Which of the following modifies proteins and lipids that will be secreted?
The endoplasmic reticulum (ER)
is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids.
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.
What is the Golgi apparatus function?
The Golgi apparatus, or Golgi complex, functions as
a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes
, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.
Where are proteins synthesized?
Ribosomes
are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.
How are proteins secreted from the cell?
Proteins destined to be secreted move through the secretory pathway in the following order:
rough ER → ER-to-Golgi transport vesicles
→ Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.
What are the examples of organelles?
A eukaryotic cell contains many organelles, for example, the
nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, and chloroplast (plastid)
. However, not all these organelles are found in only one cell or in an organism. The chloroplast, for instance, is abundant in plant cells but not in animal cells.
Which organelle is the major site of ATP synthesis?
Most eukaryotic cells contain many
mitochondria
, which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles, the main sites of ATP production during aerobic metabolism, are among the largest organelles, generally exceeded in size only by the nucleus, vacuoles, and chloroplasts.
What proteins are made by free ribosomes?
In contrast, proteins destined to remain in the cytosol or to be incorporated into the nucleus,
mitochondria, chloroplasts, or peroxisomes
are synthesized on free ribosomes and released into the cytosol when their translation is complete.
Which proteins are made by bound ribosomes?
Proteins that function within the endomembrane system (
such as lysosomal enzymes
) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
What is the powerhouse of cell?
Mitochondria
are more than just the powerhouse of the cell, they’re a dynamic network of tubules that perform multiple essential functions.
What is the full form of ATP *?
Adenosine triphosphate
(ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
What is the powerhouse?
A powerhouse is a powerful, forceful, or dominant person, group, or thing. In a literal sense, a powerhouse is
a station or plant that generates electricity
. Although it can still be used this way, terms like power plant and power station are much more common.
What is Golgi apparatus short answer?
(GOL-jee A-puh-RA-tus) A stack of small flat sacs formed by membranes inside the cell’s cytoplasm (gel-like fluid). The Golgi apparatus prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. The Golgi apparatus is a
cell organelle
. Also called Golgi body and Golgi complex.
