What is the primary action of insulin on skeletal muscle tissue?
Understand the Problem
The question is asking about the main effect that insulin has on skeletal muscle tissue, specifically which option correctly describes its primary action.
Answer
Insulin promotes glucose uptake into skeletal muscle tissue.
The primary action of insulin on skeletal muscle tissue is to promote glucose uptake into the cells.
Answer for screen readers
The primary action of insulin on skeletal muscle tissue is to promote glucose uptake into the cells.
More Information
Insulin is critical for regulating blood glucose levels by facilitating glucose uptake into cells. In skeletal muscles, this process involves activating specific signaling pathways leading to glucose transporters allowing glucose entry into the cells.
Tips
A common mistake might be confusing insulin's role in muscle tissue with its role in fat tissue, where it also promotes lipid storage. Focusing on glucose uptake and storage is key for understanding its role in muscle tissue.
