What two cellular organelles are prominent in osteoblasts?
The two cellular organelles that are prominent in osteoblasts are the endoplasmic reticulum and the Golgi apparatus. The endoplasmic reticulum is involved in protein synthesis, while the Golgi apparatus functions in packaging and modifying proteins for secretion. Both organelles are essential for the formation and secretion of bone matrix proteins by osteoblasts.
If a cell forms large quantities of protein molecules which organelles might be numerous in the cell?
The endoplasmic reticulum (ER) would be numerous in the cell as it is involved in protein synthesis and modification. The ribosomes would also be abundant as they are responsible for protein production on the ER. Lastly, the Golgi apparatus would be prevalent as it processes and packages proteins for secretion.
Do lysosomes help in secretion?
Lysosomes are not involved in secretion. Lysosomes are organelles responsible for breaking down and recycling cellular waste and debris. Secretory vesicles are responsible for transporting materials for secretion out of the cell.
What do the nucleus DNA ribosomes rough endoplasmic reticulum and the Golgi apparatus all have in common?
they are both organelles
Which organelles are not surounded by a membrane?
The ribosome is an organelle that is not surrounded by a membrane.

What organelles are found in the Epithelial tissue?
Epithelial tissue contains various organelles that support its functions, including microvilli for increased surface area, cilia for movement of substances, and tight junctions for cell adhesion and barrier formation. Additionally, they may have numerous mitochondria to provide energy for active transport processes. The presence of rough endoplasmic reticulum and Golgi apparatus is also common, as they are involved in the synthesis and secretion of proteins, such as hormones or mucus. Overall, these organelles are crucial for the specialized roles of epithelial cells in absorption, secretion, and protection.
What does ER help in synthesis of protein?
Endoplasmic reticulum (ER) plays a crucial role in the synthesis of proteins by providing a site for ribosomes to attach and synthesize proteins. The rough ER, with ribosomes attached to its surface, is involved in the synthesis of proteins that are destined for secretion or insertion into membranes. The smooth ER is involved in the synthesis of lipids and detoxification processes rather than protein synthesis.
What organelles that assembles fats?
The endoplasmic reticulum is the organelle responsible for assembling fats in a cell. It contains enzymes that catalyze the synthesis of lipids and is involved in processes such as lipid biosynthesis and detoxification of drugs.
What cell lines the small intestine assembles fats?
Smooth Endoplasmic Reticulum (organelles) cells are responsible for absorption, synthesis, and transport of fats (in intestinal cells). They catalyze reactions involved in these processes.

The ribosomes would also be abundant as they are responsible for protein production on the ER. Lastly, the Golgi apparatus would be prevalent as it processes and packages proteins for secretion.
What are some structures and organelles that are involved in protein synthesis?
Structures involved in protein synthesis include ribosomes (where actual protein synthesis occurs) and the endoplasmic reticulum (where newly synthesized proteins are processed and packaged). Organelles involved are the nucleus (where DNA is transcribed into mRNA) and the Golgi apparatus (where proteins are modified further and sorted for transport).
What is involved in the synthesis and packaging of certain molecules produced for secretion by a cell?
During synthesis, the molecules are produced by the ribosomes and then modified in the endoplasmic reticulum and Golgi apparatus. The molecules are then packaged into vesicles in the Golgi apparatus and transported to the cell membrane for secretion.
THE DOTS ON THE ENDOPLASMIC WHAT DO THEY REPRESENT?
The dots on the endoplasmic reticulum (ER) represent ribosomes, which are the cellular structures responsible for protein synthesis. When the ribosomes are attached to the rough endoplasmic reticulum (RER), it indicates that the ER is involved in the production of proteins destined for secretion or for use in the cell membrane. In contrast, the smooth endoplasmic reticulum (SER) lacks these ribosomes and is primarily involved in lipid synthesis and detoxification processes.
Do lysosomes help in secretion?
Lysosomes are not involved in secretion. Lysosomes are organelles responsible for breaking down and recycling cellular waste and debris. Secretory vesicles are responsible for transporting materials for secretion out of the cell.
What do the nucleus DNA ribosomes rough endoplasmic reticulum and the Golgi apparatus all have in common?
they are both organelles
Describe the four organelles in eukaryotes that involved in making?
In eukaryotic cells, four key organelles are involved in protein synthesis: Nucleus: Contains DNA that encodes genes, which are transcribed into messenger RNA (mRNA). Ribosomes: These can be free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER); they translate mRNA into polypeptide chains (proteins). Endoplasmic Reticulum (ER): The rough ER, studded with ribosomes, modifies and folds proteins, while the smooth ER is involved in lipid synthesis and detoxification. Golgi Apparatus: This organelle further modifies, sorts, and packages proteins for secretion or for use within the cell.
