What does the cis face of the Golgi apparatus do?
What does the cis face of the Golgi apparatus do?
The main function of the cis face of the Golgi apparatus is to receive proteins and lipids from the endoplasmic reticulum. Therefore, the CGN always faces the endoplasmic reticulum. Since the cis face receives vesicles, this face is always called the forming face. Also, it is the initial packaging stage of substances.
Which of the face of Golgi complex is associated with?
The aspect of the Golgi complex facing the ER is the cis face; the opposite side is termed the trans face. Glycoproteins are thought to be transported between the Golgi sacs via shuttle vesicles.
Do molecules enter on the cis face of the Golgi apparatus?
A striking feature of the Golgi apparatus is its distinct polarity in both structure and function. Proteins from the ER enter at its cis face (entry face), which is convex and usually oriented toward the nucleus. They are then transported through the Golgi and exit from its concave trans face (exit face).
Which face of the Golgi apparatus faces the nucleus?
Thus, the correct answer is ‘Convex and pointing towards plasma membrane.
Why does the cis face of the Golgi not face the plasma membrane?
Why does the cis face of the Golgi not face the plasma membrane? Because that face receives chemicals from the ER, which is toward the center of the cell.
Where the cis face of Golgi apparatus is located?
The cis face lies near the transitional region of the rough endoplasmic reticulum, while the trans face lies near the cell membrane. These two networks are responsible for the essential task of sorting proteins and lipids that are received (at the cis face) or released (at the trans face) by the organelle.
How is cis face convex?
The membranes of Golgi apparatus are called cisternae or face. Cis face is also called as convex or forming face. This face receives vesicles containing enzyme or protein from the ER and they have very thin membranes. Trans face is also called a concave or maturing face.
Which cell organelle is involved in synthesis of vacuoles a chloroplast B nucleus C Golgi apparatus D mitochondria?
Sol: (d) Mitochondria.
What is the function of the nuclear envelope?
The nuclear envelope separates the contents of the nucleus from the cytoplasm and provides the structural framework of the nucleus. The nuclear membranes, acting as barriers that prevent the free passage of molecules between the nucleus and the cytoplasm, maintain the nucleus as a distinct biochemical compartment.
Is Golgi apparatus is involved in processing of salivary amylase?
So, the correct answer is ‘Golgi apparatus’.
