Inner concave surface of Golgi apparatus is:
Correct answer: A. Trans face (maturation face)
- A. Trans face (maturation face)
- B. Cis face (forming face)
- C. Convex face
- D. Vesicle release face
Explanation
The Golgi apparatus consists of a series of flattened membrane-bound sacs known as cisternae, with distinct cis and trans faces. The inner concave surface is the trans face, or maturation face, responsible for packaging and dispatching vesicles to their destinations. This contrasts with the cis face, which is the entry point for vesicles from the endoplasmic reticulum and is convex. The terms 'convex face' and 'vesicle release face' do not specifically describe any part of the Golgi apparatus.
