Nicotinic receptor activation causes the opening of the channel formed by the receptor. This increases the Na+ movement into the target cell, leading to depolarization and generation of the action potential. This rapidly developing change, termed a fast EPSP, is illustrated in Figures 4.3, and 6.2.
Just like red pepper, black pepper has a thermogenic effect when ingested. The spice stimulates your metabolism and thus temporarily increases body heat. A higher basal metabolic rate means higher energy expenditure or more calories burned.
Common symptoms of allergic reaction to pepper depend on how the pepper comes in contact with you. Since black, white and green peppers are the same fruit in different stages of processing, if you are allergic to black pepper, it will be no surprise to find you are allergic to white and green peppers as well.
