What is the exact transport mechanism by which proteins travel through the Golgi apparatus?
The Golgi apparatus is important in modifying, sorting and packaging macromolecules for secretion. Some people say it is similar to a post office where it packages and labels items and then sends it to different parts of the cell.
The vesicles that leave the RER are sent to the cis face of the Golgi where they fuse and empty their contents into the lumen. Once there they are modified and sorted. Then send on their way.
The transport mechanism which proteins move through the Golgi is not clear.

What is the cytoplasmic structures functions in the transport of vesicles from the endoplasmic reticulum to the Golgi apparatus?
Cytoplasmic structures, particularly microtubules and motor proteins, play a crucial role in the transport of vesicles from the endoplasmic reticulum (ER) to the Golgi apparatus. Microtubules serve as tracks along which motor proteins, such as kinesins and dyneins, move the vesicles. These motor proteins utilize ATP to facilitate the movement of vesicles through the cytoplasm, ensuring efficient and directed transport. This process is essential for the proper distribution of proteins and lipids synthesized in the ER to their respective destinations for further processing and sorting in the Golgi apparatus.
When molecules pass through a cell membrane using special proteins called transport proteins?
When molecules pass through a cell membrane using special proteins called transport proteins, this process is known as facilitated diffusion or active transport, depending on whether energy is required. Transport proteins help move substances across the membrane by forming channels or carriers that allow specific molecules, such as glucose or ions, to enter or exit the cell. This mechanism ensures that essential nutrients are absorbed while waste products are expelled, maintaining cellular homeostasis.
Can proteins pass through transport proteins?
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
How much ATP does this cost the cell if it uses transport proteins?
The cost of ATP for a cell using transport proteins depends on the type of transport mechanism employed. For active transport, which moves substances against their concentration gradient, the process typically requires the hydrolysis of one ATP molecule per transport cycle. In contrast, facilitated diffusion through transport proteins does not require ATP, as it occurs along the concentration gradient. Therefore, if active transport is utilized, it costs the cell one ATP per transport event.
What moves proteins around cells?
Proteins are moved around cells primarily by motor proteins such as kinesins and dyneins, which utilize ATP as an energy source to transport proteins along microtubule tracks. Additionally, vesicles and membrane-enclosed compartments can also facilitate the movement of proteins within cells through processes like endocytosis and exocytosis.
How are proteins transported to the Golgi apparatus?
Proteins are transported to the Golgi apparatus through a process called vesicular transport. This involves the proteins being packaged into vesicles at the endoplasmic reticulum and then transported to the Golgi apparatus where they are further processed and sorted for distribution within the cell.
How do proteins reach the Golgi apparatus within a cell?
Proteins are transported to the Golgi apparatus within a cell through a process called vesicular transport. This involves the proteins being packaged into vesicles at the endoplasmic reticulum and then transported to the Golgi apparatus where they are further processed and sorted for distribution within the cell.
How are proteins transported from the endoplasmic reticulum to the Golgi apparatus?
Proteins are transported from the endoplasmic reticulum to the Golgi apparatus through small vesicles that bud off from the ER and fuse with the Golgi membrane. This process is called vesicular transport and is essential for the proper functioning of the cell.
What is the cytoplasmic structures functions in the transport of vesicles from the endoplasmic reticulum to the Golgi apparatus?
Cytoplasmic structures, particularly microtubules and motor proteins, play a crucial role in the transport of vesicles from the endoplasmic reticulum (ER) to the Golgi apparatus.

What is the name of the organelle that moves proteins and other substances through the cell?
The endoplasmic reticulum are transport tubes made of membrane that move proteins and other materials through the cell, most likely sending them towards the Golgi apparatus/body.
What is the function of vesicles in the synthesis of proteins and the release of those proteins outside the cell?
Vesicles help transport newly synthesized proteins from the endoplasmic reticulum to the Golgi apparatus for further processing and sorting. Once the proteins are modified in the Golgi, vesicles are used to transport them to the cell membrane for secretion outside the cell through exocytosis.
How do proteins get from the ER to the Golgi apparatus?

How does the Golgi apparatus continue the function of the rough er?
The Golgi apparatus receives proteins from the rough ER, modifies them by adding sugars and lipids, and sorts them into vesicles for transport to different parts of the cell or for secretion outside the cell. In this way, the Golgi apparatus processes and packages proteins synthesized in the rough ER for distribution and use by the cell.

What organelle does cell transport occur in?
Most of the cell transport occurs through the use of vesicles created by the Golgi apparatus.
