What process is indicated by C?
What process is indicated by C? exocytosis of secreted proteins. The event indicated by C includes the fusion of a secretory vesiclel with the plasma membrane and the subsequent release of the vesicle contents to the extracelluar space.
Which organelle is labeled C and stores DNA?
Nucleus. Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid).
Where is the smooth endoplasmic reticulum located?
The smooth endoplasmic reticulum like the rough endoplasmic reticulum is connected to the nuclear envelope. The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is reticular in appearance.
Which of the following best describes the structure of the cell membrane?
Which of the following best describes the structure of the plasma membrane? The plasma membrane is a phospholipid bilayer surrounding the cell.
Which of the following lists the regions of the pharynx from superior to inferior?
From superior to inferior, the pharynx is divided into three regions: the nasopharynx, oropharynx, and laryngopharynx.
Which specific protein structure is indicated by the letter c?
What process is indicated by C? exocytosis of secreted proteins. The event indicated by C includes the fusion of a secretory vesiclel with the plasma membrane and the subsequent release of the vesicle contents to the extracelluar space.
What does the small circular structure indicated by the letter C represent?
What does the small circular structure indicated by the letter C represent? The mitochondria each have a small circular DNA chromosome that contains genes for several mitochondrial proteins. These proteins are translated within the mitochondria (on the ribosomes indicated by the small red dots).
What is the function of organelle C?
Organelles and their Functions
| Organelle | Cell Type | Function |
|---|---|---|
| Vacuoles | Eukaryotic | Store water and nutrients |
| Vesicles | Eukaryotic | Transport materials around the cell |
| Cell Membrane | All | A thin flexible barrier that separates the cell from its environment |
| Cell Wall | Plants, fungi and prokaryotes | Rigid barrier that protects the cell |

What is in the Golgi apparatus?
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.
What is the structure of the rough endoplasmic reticulum?
rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
What is the structure of ER?
The endoplasmic reticulum is the largest single structure in eukaryotic cells. It consists of a range of interconnected shapes, including sheets and tubules, and comprises a lumen enclosed by a membrane that is continuous with the membrane that surrounds the nucleus of the cell (Figure 1).
What is the structure of a plasma membrane?
Plasma Membrane Structure The plasma membrane is composed of a phospholipid bilayer, which is two layers of phospholipids back-to-back. Phospholipids are lipids with a phosphate group attached to them. The phospholipids have one head and two tails. The head is polar and hydrophilic, or water-loving.
Which structure is the cytoplasm?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
Where is laryngopharynx located?
pharynx The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass. Specifically, it refers to the point at which the pharynx divides anteriorly into the larynx and posteriorly into the esophagus.
What are the three regions of nasal chamber?
Within each cavity are three regions; nasal vestibule, respiratory region, and olfactory region.
Is the tertiary structure of protein?
The tertiary structure of a protein refers to the overall three-dimensional arrangement of its polypeptide chain in space. It is generally stabilized by outside polar hydrophilic hydrogen and ionic bond interactions, and internal hydrophobic interactions between nonpolar amino acid side chains (Fig.
What organelle is indicated by the letter c what cellular process occurs here?
What organelle is indicated by the letter c what cellular process occurs here? The event indicated by C includes the fusion of a secretory vesicle with the plasma membrane and the subsequent release of the vesicle contents to the extracellular space.
In which part of the cell are organelles found?
cytoplasm These organelles are found in the cytoplasm, a viscous liquid found within the cell membrane that houses the organelles and is the location of most of the action happening in a cell.
What is in Golgi apparatus?
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.
Where is Golgi apparatus located?
The Golgi is located right near the nucleus. It's called a perinuclear body, and it's actually right near the endoplasmic reticulum as well. And when proteins come out of the endoplasmic reticulum, they go into the Golgi for further processing.
What is the function and location of Golgi apparatus?
The Golgi apparatus is a series of stacked membranes that are located within the cytoplasm (i.e., gel-like fluid held in the cell membrane) in all eukaryotic cells (i.e., complex cells). It can typically be found adjacent to the nucleus and rough endoplasmic reticulum (an organelle involved in protein synthesis).
What is Golgi apparatus structure?
The Golgi apparatus is a central intracellular membrane organelle for trafficking and modification of proteins and lipids. Its basic structure is a stack of tightly aligned flat cisternae. In mammalian cells, dozens of stacks are concentrated in the pericentriolar region and laterally connected to form a ribbon.
What is RER and SER?
Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER). The SER is generally used for the creation/ storage of lipids and steroids, while the RER plays a significant role in the synthesis of various proteins.
What is structure of Golgi apparatus?
The Golgi apparatus is a central intracellular membrane organelle for trafficking and modification of proteins and lipids. Its basic structure is a stack of tightly aligned flat cisternae. In mammalian cells, dozens of stacks are concentrated in the pericentriolar region and laterally connected to form a ribbon.
Where is the plasma membrane located?
cells The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface.
Where is the cell membrane located?
The cell membrane or plasma membrane is the outer covering of the living cell, which encloses the cytoplasm and the nucleus.
Where is cytoplasm located?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
Where is cytoplasm found in a cell?
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
What is the structure of the pharynx?
The pharynx anatomy includes: Nasopharynx: The top part of the throat connects to the nasal cavities (nose) and lets air pass through. Oropharynx: The middle part of the throat connects to the oral cavity (mouth). It allows air, food and fluid to pass through.
