What else can I help you with?
What are the stacks of membrane covered sacs that package and transport protein to the outside of the cell called?
The stacks of membrane-covered sacs that package and transport proteins to the outside of the cell are called Golgi apparatus or Golgi bodies. They receive proteins from the endoplasmic reticulum, modify them, and package them into vesicles for transport.
What are the membrane-bound sacs the Golgi complex packs proteins and other materials into called?
The membrane-bound sacs in the Golgi complex are called vesicles. These vesicles transport and package proteins and other materials synthesized within the cell for storage or secretion.
What is Golgi body?
Golgi bodies are stacked, flattened membranes which sort proteins and other cellular substances and package them into membrane-bound structures called vesicles.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What are proteins embedded in the plasma membrane called?
Proteins embedded in the plasma membrane are called integral membrane proteins. These proteins are permanently attached to the lipid bilayer and play important roles in various cellular functions such as cell signaling, transport, and cell recognition.
What membrane bound sacs package and transport proteins?
The Golgi apparatus is responsible for packaging and modifying proteins before they are transported to their final destinations within the cell or outside of the cell. It consists of membrane-bound sacs called cisternae that help in the processing and sorting of proteins.
Are carrier proteins peripheral membrane proteins?
The cell membranes that can act as channels are called integral proteins. Peripheral proteins are the ones that are attached to just one side of the cell membrane.
Structure of a membrane?
An animal cell membrane is made up of something called a phospholipid bilayer. Along with that, there are proteins that sit on the membrane called membrane proteins. Membrane proteins can either be receptor proteins, which receive signals coming to the cell, channel proteins, which allow large molecules such as lipids (fats) and proteins to come through, or lastly, marker proteins, which identify the type of cell it is.
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
The process is called facilitated diffusion. It is a type of passive transport that involves the movement of molecules across a membrane with the help of specific proteins called carrier proteins or channel proteins. These proteins assist the molecules in crossing the membrane by providing a pathway.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.
What proteins are embedded in the plasma membrane?
They are called integral proteins
How do proteins leave the cell?
Proteins leave the cell through a process called exocytosis, where they are packaged into vesicles and transported to the cell membrane. The vesicle then fuses with the cell membrane, releasing the proteins outside of the cell.
