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.
Cayenne pepper contains capsaicin that helps stimulate the proper flow of blood throughout the body and organs. It also strengthens the arteries and capillaries. Plus, it helps reduce symptoms of poor blood circulation like pain, headaches, cold feet and tingling sensations in the legs.
