Now, this also means that T three and T four, because they are lipid soluble, they can easily dissolve across our cell membrane. And that means they basically enter the nucleus of our cell that targets out, and they influence our cell on a transcriptional level. So they basically affect the different processes in our body, especially protein synthesis. So it turns out that T three and T four hormones affect the different types of cells in our body in very similar ways. They essentially affect the basal metabolic rate, also known as the resting metabolic rate. So this concept basically incorporates all the different processes and reactions that take place in our body in our cells.
