Question

What is vesicular transport? Examples? Does it require NRG?

a. The movement of vesicles within the Golgi apparatus. Yes, it requires energy.
b. The fusion of vesicles with the plasma membrane. No, it does not require energy.
c. The uptake of nutrients by endocytosis. Yes, it requires energy.
d. The release of neurotransmitters by exocytosis. Yes, it requires energy.

Answer 1

Vesicular transport is a type of active transport that involves the movement of substances across the plasma membrane using vesicles. It requires energy. Therefore, of the given options, option d is the correct one. The release of neurotransmitters by exocytosis. Yes, it requires energy.

Step-by-step explanation:

Vesicular transport is a type of active transport that involves the movement of substances across the plasma membrane using vesicles. It requires energy in the form of ATP. There are two types of vesicular transport: endocytosis, which is the uptake of nutrients by engulfing them with the plasma membrane, and exocytosis, which is the release of substances, such as neurotransmitters, from the cell.

Examples of vesicular transport include:

1. Endocytosis, where substances are brought into the cell. This can include phagocytosis, which is the ingestion of large particles, and pinocytosis, which is the uptake of fluid containing dissolved substances.
2. Exocytosis, where substances are released from the cell. For example, vesicles from the Golgi apparatus fuse with the plasma membrane to release proteins outside the cell.

Therefore, of the given options, option d is the correct one. Vesicular transport, specifically exocytosis, requires energy.
