How many times greater in volume and surface area will mature cells?
When the budding cell matures, it will be approximately how many times greater in volume and how many times greater in surface area than its current size?

As the new cell grows, its plasma membrane needs to expand to contain the increased volume of the cell. Calculate the surface area of each cell using the formula for the surface area of a sphere:
What is the approximate diameter of a membrane?
Due to these extra constituents that also include lipopolysaccharides, the overall membrane width is variably reported to be anywhere between 4 and 10 nm. The value of 4 nm is most representative of the membrane shaved off from its outer and inner protrusions.

What is the function of the nuclear pore complex found in eukaryotes quizlet?
What is the function of the nuclear pore complex found in eukaryotes? It regulates the movement of proteins and RNAs into and out of the nucleus.
Which structure is the site of the synthesis of proteins that may eventually be exported from the cell?
Ribosomes that synthesize proteins destined for insertion into cellular membranes or for export from the cell associate with specialized regions of the ER, called the rough ER owing to the attached ribosomes. Cell type-dependent and may function in lipid synthesis, carbohydrate metabolism, and drug detoxification.
What is the approximate diameter of the budding cell?
What is the approximate surface area of the budding cell? (Remember that you approximated the diameter of the budding cell to be 3 µm.)
Which of the following will be the correct average size of a typical eukaryotic cell?
The best explanation: The size of a typical eukaryotic cell is 10 – 20 μm.06-Aug-2021
What is the function of the nuclear pore complex found in eukaryotes *?
Nuclear pore complexes allow the transport of molecules across the nuclear envelope. This transport includes RNA and ribosomal proteins moving from nucleus to the cytoplasm and proteins (such as DNA polymerase and lamins), carbohydrates, signaling molecules and lipids moving into the nucleus.
What is the function of the nuclear pore complex found in eukaryote?
The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope. This envelope safeguards the DNA contained in the nucleus.
What best describes the function of the nuclear pore complex found in eukaryotic cells?
Which of the following statements best describes the function of the nuclear pore complex found in eukaryotic cells? It regulates the movement of proteins and RNAs into and out of the nucleus. Examination of a cell by transmission electron microscopy reveals a high density of ribosomes in the cytoplasm.
How does the ER and Golgi produce mature proteins?
After translation on ribosomes in the cytosolic compartment all proteins are processed either in the cytosol or in the ER/Golgi system. The initial stages of protein processing involving folding. ... Cleavage occurs commonly in the case of digestive enzymes and other secreted proteins (e.g. insulin).
Where is protein synthesis in the cell?
RibosomesRibosomes are the sites in a cell in which protein synthesis takes place.
Which structure is the site of the synthesis of proteins destined for export from the cell quizlet?
All proteins are synthesized by ribosomes in the cell. Some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. Most proteins made by free ribosomes function in the cytosol.
Which structure is the site of the synthesis of proteins destined for export from the cell quizlet?
All proteins are synthesized by ribosomes in the cell. Some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. Most proteins made by free ribosomes function in the cytosol.
Which of the following is a major cause of size limits for certain types of cells?
Which of the following is a major cause of the size limits for certain types of cells? The need for a surface area of sufficient area to allow the cell's function.
Which of the following statements best describes some aspect of cytoskeleton structure or function in eukaryotic cells?
Which of the following statements best describes some aspect of cytoskeleton structure or function in eukaryotic cells? ... It glues adjacent cells together. The cell walls of bacteria, fungi, and plant cells, and the extracellular matrix of animal cells are all external to the plasma membrane.
Which of the following functions is not associated with the endomembrane system?
Mitochondria, chloroplast and peroxisomes are not the part of endomembrane system because their function are not coordinated with the same.
Which structure is the site of protein synthesis of proteins destined for export from the cell?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
Which structures is the site of the synthesis of proteins destined for export from the cell?
Proteins that will be exported, or secreted, from the cell, are generally produced in the rough endoplasmic reticulum (rough ER).
Which of the following aspects limits the size of the cell?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes.05-Dec-2014
What kind of cell would you not expect to contain a larger than average number of mitochondria?
Different cell types have different numbers of mitochondria. For instance, mature red blood cells have none at all, whereas liver cells can have more than 2,000. Cells with a high demand for energy tend to have greater numbers of mitochondria.
What cells have large numbers of ribosomes?
Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.
Which of the following parameters is most likely to limit the maximum size of the cell?
The key factor that limits the size of a cell is the ratio of its surface area to its volume. Small cell size maximizes the ability of diffusion and motor protein to transport nutrients and waste products. Cell size affects the ability of the cell to communicate instructions for cellular functions.
Which of the following are likely to limit the maximum size of a cell?
Factors limiting the size of cells include: Surface area to volume ratio. (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane.11-Dec-2021
Which of the following statements best describes some aspect of protein secretion from prokaryotic cells?
Which of the following statements correctly describes some aspect of protein secretion from prokaryotic cells? Proteins that are secreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
What is the cytosol function?
Function. The cytosol has no single function and is instead the site of multiple cell processes. Examples of these processes include signal transduction from the cell membrane to sites within the cell, such as the cell nucleus, or organelles.
Which structure listed below is not part of the endomembrane system?
The correct answer is B) Mitochondria. Lysosomes are the cell organelles that have digestive enzymes present within its membrane.
Which organelle is not considered part of the endomembrane system?
Reason: Mitochondria, Chloroplast, and Peroxisomes are not part of the Endomembrane system because their functions are not coordinated with the same.
