What would the Golgi apparatus be in a factory?
The Golgi apparatus is analogous to the finishing and packing room in a factory. Once the ribosome finishes manufacturing a protein in the rough ER, the protein needs to be prepared for use or export.
Where are secretory vesicles produced?
Secretory vesicles are synthesized in the Golgi apparatus so the correct answer is A. The smooth endoplasmic reticulum synthesizes lipids.
How are ribosomes like a factory?
Ribosome are like a factory, because ribosomes make proteins like factories make different products. The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate.
What would the nucleolus be in a factory?
Factory Floor: The job of the Nucleolus is to produce ribosomes for the cell. It has a very important job, creating the ribosomes which then make crucial proteins.
What organelle is considered a factory?
Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.
Where do proteins go after Golgi?
The Golgi apparatus is often found in close proximity to the ER in cells. Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface.
Who produces secretory vesicles?
The cytoskeleton, especially microtubules, contributes to the transport of newly synthesized secretory vesicles from the Golgi to the cell surface and also may direct them toward a specific plasma membrane domain. As shown in Fig. 1, several stages have been recognized in exocytosis.
What are secretory vesicles made out of?
Secretory Vesicle Structure It is enclosed by an outer membrane known as the bilayers of lipids. This layer is made up of clusters of hydrophilic heads and hydrophilic tails. Vesicles are the small membrane-enclosed sacs that are involved in the storage and transport of substances from one cell to another.
What everyday object is like a ribosome?
What everyday object is like ribosomes? The ribosomes in a cell are like the kitchen in a house. In the kitchen, meals are cooked and prepared. It is similar to ribosomes using amino acids to make proteins.
What are the parts of factory?

What are peroxisomes in a factory?
Plant peroxisomes are organelles enclosed by a single membrane whose biochemical composition has the capacity to adapt depending on the plant tissue, developmental stage, as well as internal and external cellular stimuli.
Why nucleolus is called ribosome factory?
Ans: Because nucleolus is the location of the active synthesis of rRNA. rRNA is required for the synthesis of ribosomes along with ribosomal proteins.
What is an example of exocytosis?
Specific examples of exocytosis include cells of the stomach and pancreas producing and secreting digestive enzymes through exocytosis ( Figure 3.1.10) and endocrine cells producing and secreting hormones that are sent throughout the body.
What is the difference between pinocytosis and receptor-mediated endocytose?
(b) In pinocytosis, the cell takes in small particles in fluid. (c) In contrast, receptor-mediated endocytosis is quite selective. When external receptors bind a specific ligand, the cell responds by endocytosing the ligand.
What part of the cell membrane does the receptor endocytose?
Once the surface receptors have bound sufficient amounts of the specific substance (the receptor’s ligand), the cell will endocytose the part of the cell membrane containing the receptor-ligand complexes. Iron, a required component of hemoglobin, is endocytosed by red blood cells in this way.
How do cells regulate the endocytosis of specific substances?
When external receptors bind a specific ligand, the cell responds by endocytosing the ligand. Phagocytosis and pinocytosis take in large portions of extracellular material, and they are typically not highly selective in the substances they bring in. Cells regulate the endocytosis of specific substances via receptor-mediated endocytosis.
