So inside our body, to be able to fine tune the regulation of this biochemical process, we basically depend on different types of isozymes of glucose transporters. And in fact, we have over ten different isozymes of glucose transporters. And in this lecture, we're going to focus on the first five, perhaps the most important of these glucose transporter molecules. So we have glute one, glute two, glute three, glute four and glute five, where glute basically stands for glucose transporter. Let's begin with glute one and glute three. Now, glute one as well as glute three are actually responsible for establishing something called the basal rate of glucose uptake.
