During a cellular study, a biologist observes vesicles containing fully modified glycoproteins budding off and exiting from a specific face of the Golgi apparatus. Which of the following combinations of terms correctly describes the face from which these vesicles are exiting?
Options
- Acis face, convex, and forming face
- Btrans face, concave, and maturing face
- Ctrans face, convex, and maturing face
- Dcis face, concave, and forming face
Correct answer
B. trans face, concave, and maturing face
Step-by-step solution
The Golgi apparatus receives materials from the endoplasmic reticulum at its entry face and releases modified materials (such as glycoproteins) from its exit face. Vesicles containing fully modified proteins bud off from the exit face, which is known as the trans face. According to NCERT, the trans face is morphologically concave in shape and is functionally referred to as the maturing face. The cis face is the convex, forming face where vesicles from the ER initially fuse, making options containing 'cis' or 'conve
