Type II diabetes results from the body's inability to properly use which of the following?

Type II diabetes primarily results from the body's inability to properly use insulin. In a healthy individual, insulin is a crucial hormone produced by the pancreas that facilitates the uptake of glucose from the bloodstream into the cells for energy. When someone has Type II diabetes, the body's cells become resistant to insulin, meaning they do not respond effectively to the hormone. This insulin resistance leads to higher levels of glucose in the bloodstream because the cells are not able to absorb it adequately.

Understanding this concept is essential as it highlights the role of insulin in regulating blood sugar levels. Over time, if insulin is not used correctly, the pancreas struggles to produce enough insulin to compensate for this resistance, ultimately leading to abnormal blood sugar levels and associated complications.

Other terms like glucose, glycogen, and lactate pertain to various metabolic processes in the body. Glucose is the sugar that blood transports for energy, glycogen is the stored form of glucose in the liver and muscles, and lactate is produced during anaerobic metabolism. Although these substances are related to the process of energy production and metabolism, they do not specifically represent the problem associated with Type II diabetes, which revolves around the effectiveness of insulin.
