Where does synthesis of membrane proteins and secretory proteins happen?
Synthesis of proteins occurs in the Rough Endoplasmic Reticulum.
What participates in lipid synthesis and synthesis of membrane or secreted proteins?
Lipid synthesis primarily involves enzymes located in the endoplasmic reticulum (ER). These enzymes include fatty acid synthase, which synthesizes fatty acids, and enzymes involved in glycerolipid and phospholipid synthesis. In addition, the synthesis of membrane or secreted proteins involves ribosomes attached to the ER, where these proteins are synthesized and processed before being transported to their target destinations.
What is a flattened membrane that packages proteins?
The endoplasmic reticulum (ER) is a flattened membrane that packages proteins. It plays a critical role in the synthesis, folding, and sorting of proteins. The ER consists of two main regions: the rough ER, which is studded with ribosomes and involved in protein synthesis, and the smooth ER, which lacks ribosomes and is involved in lipid metabolism and detoxification.
After a cell was treated with a certain chemical the ribosomes stopped functioning which cell activity was immediately affected by this change in ribosome funcation?
synthesis of proteins. And since the synthesis of proteins is necessary for maintenance of the cell, most of the processess will be stopped afterwards.
Which type of cells are surrounded by a plasma membrane made of two layers of phosphilipids and integrated proteins?
All living eukaryotic cells are surrounded by a plasma membrane made of two layers of phospholipids and integrated proteins. Prokaryotic cells also show this structure, but have additional layers of peptidoglycan and occasionally lipoproteins.
Where does synthesis of membrane proteins and secretory proteins happen?
Synthesis of proteins occurs in the Rough Endoplasmic Reticulum.
What are the types of proteins synthesize in the free ribosome?
Protein synthesis on ribosomes attached to ER membrane: secreted proteins integral membrane proteins soluble proteins destined for life in a membrane bound compartment
How is a cell affected if a cell membrane doesn't have any membrane proteins?
It dies.
Is protein sythesis a function made by the cell membrane?
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
What is the function of the free ribosomes?
Free ribosomes, present in the cytoplasm, make proteins that remain in the cytosol, cytosolic proteins. Whereas membrane bound ribosomes (on Rough ER) make membrane proteins and secretory proteins etc. Hope this helps.

What are the functions of a plasma membrane?
- Outer membrane of cell that controls cellular traffic- Contains proteins (left, gray) that span through the membrane and allow passage of materials- Proteins are surrounded by a phospholipid bi-layer
Which would least be affected by defective receptor proteins on a cell membrane?
Diffusion

diffusion

Which of the following incorrectly matches the type of cell type of protein and site of the proteins synthesis?
prokaryote, plasma membrane protein, ribosome bound to plasma membrane
What is involved in the synthesis of proteins?
RNA is involved in the synthesis of proteins.
