Answer:
Glut4 is only expressed in insulin-sensitive skeletal an heart muscles and fat tissues.
Explanation:
Glucose transporters represent a group of integral membrane proteins that allow the transport of glucose molecules across the plasma membrane by the mechanism of facilitated diffusion (i.e., without direct coupling to ATP hydrolysis). In humans, the Glucose Transporter type 4 (GLUT-4) is a glucose transporter encoded by the SLC2A4 gene. This protein plays a critical role in regulating glucose homeostasis by enabling to increase the transport of glucose in response to elevated blood insulin levels in adipocytes, skeletal and cardiac muscle tissues.
Answer: We can tell how life existed on earth and how different plants and animals are related to each other. Often we can work out how and how and where they lived, and use this information to find out about ancient environments. Fossils can tell us about the past.
