WebHow do SSRIs work? SSRIs increase levels of serotonin in the brain by preventing the reuptake of serotonin by nerves. Having more serotonin available in the nerve synapse means that it can transmit messages easier. All SSRI antidepressants are thought to work in this way. What types of antidepressants are there? WebShunting inhibition is indirect inhibition. Direct vs Indirect Inhibition Direct Inhibition-Molecules that directly inhibit the function or transmission of other molecules or functions in a cell. This is different from secondary inhibition, or molecules that effect a third part that is responsible for regulating the cell.

WebWhen an allosteric inhibitor binds to an enzyme, all active sites on the protein subunits are changed slightly so that they work less well. There are also allosteric activators. Some allosteric activators bind to locations on an enzyme other than the active site, causing an increase in the function of the active site.
