Secretion of the neurotransmitter serotonin, which is a water-soluble amine molecule
Explanation:
Exocytosis is defined as the process where cell transports secretary products which are packaged in transport vesicles such as antibodies, peptide hormones, secretory proteins, and enzymes with the help of cytoplasm to the plasma membrane.
Some example of exocytosis are:
1) Neurotransmitters secrets from nerve cells.
2) Antigens which helps to stimulate the immune response.
Option A, secretion of the neurotransmitter serotonin, which is a water-soluble amine molecule
Explanation:
Exocytosis is a transport mechanism used by cells to transport large molecules out of the cell though the the cytoplasm to the plasma membrane. The secreted molecules are packaged in vesicles. The neural cell’s soma releases large transmitter molecules (serotonin) until it produces stimulus modulated by active neurons, glia and blood vessels. This somatic exocytosis of serotonin is stimulated by sequence of intracellular Ca2+ transients that activates L-type channels thereby leading to exocytosis of serotonin from vesicles to plasma membrane
Wind pollinated have light and small pollen grains to be easily carried away. They also lack petals or have small ones, so that the pollen can be exposed and easily swept by wind.
