The rough endoplasmic reticulum is this organelle and it acts as an assembly line in a factory. Ribosomes are positioned on the rough endoplasmic reticulum where the proteins are assembled and act as the work stations. These proteins are usually shipped out of the cell. Other ribosomes in the cytoplasm make proteins as well but they are usually for use by the cell.
Endoplasmic reticulum is the organelle associated with protein synthesis. The information to do so is obtained from DNA through mRNA. Ribosomes also play key role in assembling the desired aminoacids for synthesis of proteins.

What else can I help you with?
What is the function of the rough endoplasmic reticulum in the mammalian cell?
Rough endoplasmic reticulum is studded with ribosomes, which make proteins. It makes proteins that are destined to leave the cell to go elsewhere, for example, proteins in a mothers breast mild.
Which molecules help control movement of substances through cell membranes?
Proteins such as transporters, channels, and pumps are the main molecules that help control the movement of substances through cell membranes. These proteins facilitate the selective transport of ions, molecules, and other substances into and out of cells, maintaining proper cellular function. Additionally, phospholipids in the membrane also play a role in regulating the movement of substances across the cell membrane.
What large molecules use proteins to help move across cell membranes?
Large molecules such as glucose, amino acids, and ions use transporter proteins to help facilitate their movement across cell membranes. These proteins provide a channel or carrier to help these molecules pass through the membrane, overcoming the barrier imposed by the lipid bilayer.
What do mitrochondrial membranes and thykaloid have in common?
Mitochondrial membranes and thylakoids share similarities in their roles as sites of energy conversion within cells. Both structures contain folded membranes that increase surface area, facilitating processes like oxidative phosphorylation in mitochondria and photosynthesis in thylakoids. Additionally, both contain proteins and complexes essential for their respective functions—such as electron transport chains—highlighting their importance in energy metabolism. Finally, both membranes have distinct compartments that help create electrochemical gradients essential for ATP production.
What are the two main components of cell membranes?
The two main components of cell membranes are phospholipids and proteins. Phospholipids form a lipid bilayer that gives the membrane structure and acts as a barrier to the passage of molecules, while proteins function as channels, receptors, and enzymes that help with various cellular processes.

What uses channel proteins to help it across the cell membranes?
Water is one specific molecule. Its channel proteins are called aquaporins.

Are protein part of cell membranes and store energy?
no proteins do not store energy they help active transport
What role do proteins play in the structure and function of plasma membranes?
Proteins in plasma membranes help maintain the structure and regulate the functions of cells by serving as channels for molecules to enter and exit the cell, as well as facilitating cell signaling and recognition.
How do proteins enter the mitochondria and what is the process involved?
Proteins enter the mitochondria through a process called protein import. This involves the recognition of specific targeting signals on the protein by receptors on the mitochondrial outer membrane. The protein is then guided through channels in the outer and inner membranes of the mitochondria, with the help of protein translocases, to reach its final destination within the organelle.

Are cellular organelles associated with membranes?
Yes, all organelles within the cell are bound by membranes that are all made up of the same basic structure but have different kinds of proteins within them that allow them to have a distinct cellular function. These membranes are always in exchange with one another as well, things called vesicles will bud off from one membrane and fuse with another to deliver things from one organelle to another. So for example the nucleus is bound by the nuclear membrane and the cell is bound by the plasma membrane. Parts of the plasma membrane can bud off to form a vesicle, basically like a bubble and can travel to the nucleus (or any other organelle) where it will fuse with the nuclear membrane (or the membrane of the particular organelle) and deliver its contents into the interior of the organelle or simply deliver new membrane to that organelle. There is an entire branch of scientific research that is concerned with understanding how this whole process works and how membranes bud and form vesicles and fuse, and what is contained within the different membranes of the different organelles, its called membrane trafficking. Hope that helps!
Is this question true or false most polar molecules cannot cross cell membranes without the help of certain proteins?
true
Which integral proteins with carbohydrates sugars attached that stick out on the exterior surface of cell membranes help recognize self?
Glycoproteins are integral proteins with carbohydrate sugars attached that stick out on the exterior surface of cell membranes to help recognize self. They play a crucial role in cell recognition and immune response by distinguishing between self and non-self cells.
