Why must transport proteins be peripheral proteins?
Transport proteins must be peripheral proteins because they need to be able to move within the cell membrane to facilitate the transport of molecules across the membrane. Peripheral proteins are not embedded within the lipid bilayer of the membrane, allowing them to move more freely and interact with molecules on both sides of the membrane. This mobility is essential for transport proteins to effectively transport molecules across the cell membrane.
Where in the mitochondria is the proteins of the ETC located?
The proteins of the electron transport chain (ETC) are located in the inner mitochondrial membrane. This is where the series of complexes involved in electron transfer and ATP production are situated.
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
What are proteins that are transported in vesicles made by?
Transport vesicles play a key part in moving molecules to and from the membrane-confined chambers of the secretory pathway. Proteins are transported in vesicles; the proteins are made on the cytosolic side of membranes.
Transport proteins and cholesterol are embedded in this structure?
The Cell Membrane
Is proteins production part of membrane proteins?
Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
Where does synthesis of membrane proteins and secretory proteins happen?
Synthesis of proteins occurs in the Rough Endoplasmic Reticulum.
What is the difference between a transport vesicle and a secretory vesicle?
Transport vesicles Transport vesicles can move molecules between locations inside the cell, e.g., proteins from the rough endoplasmic reticulum to the Golgi apparatus. Membrane-bound and secreted proteins are made on ribosomes found in the rough endoplasmic reticulum. Most of these proteins mature in the Golgi apparatus before going to their final destination which may be to lysosomes, peroxisomes, or outside of the cell. These proteins travel within the cell inside of transport vesicles. Secretory vesicles Secretory vesicles contain materials that are to be excreted from the cell. Cells have many reasons to excrete materials. One reason is to dispose of wastes. Another reason is tied to the function of the cell. Within a larger organism, some cells are specialized to produce certain chemicals. These chemicals are stored in secretory vesicles and released when needed.
What biomolecule helps transport molecules across the membrane?
proteins

How is the Proteins that are secreted from a eukaryotic cell must first travel through the endomembrane system set up?
As they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.
Where are Secretory proteins and membrane molecules are synthesized mainly by what?
Secretory proteins and membrane molecules are mainly synthesized by the endoplasmic reticulum (ER) in eukaryotic cells. The ER is a network of membranes where proteins are synthesized and processed before being transported to their final destinations within the cell.
Where in the mitochondria is the proteins of the ETC located?
The proteins of the electron transport chain (ETC) are located in the inner mitochondrial membrane. This is where the series of complexes involved in electron transfer and ATP production are situated.

What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
Which of these is not an essential role of salts in the body neuromudcular activity membrane permeability secretory activity or anabolism or proteins?
Anabolism of proteins is not an essential role of salts in the body. Salts mainly play essential roles in neuromuscular activity, membrane permeability, and secretory activity in the body. They help regulate various physiological processes and maintain homeostasis.
What do the channel proteins in the cell membrane do?
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
