Final answer:
Chromium works closely with insulin to regulate blood sugar levels by enhancing A) insulin's actions.
Step-by-step explanation:
Chromium is a trace mineral that works closely with insulin to help regulate blood sugar levels. It is important in the metabolism of carbohydrates, fats, and proteins. The correct answer to the question, "With what does chromium work closely?" is (a) Insulin.
Chromium enhances the actions of insulin, which is crucial for the metabolism and storage of carbohydrate, fat, and protein in the body. Insulin helps to control the amount of sugar (glucose) in the blood and allows cells to absorb glucose for energy. A deficiency in chromium may lead to impaired glucose tolerance and contribute to the development of diabetes.
There are two common forms of chromium: Cr(III) and Cr(VI). Cr(III) is present in many dietary supplements, has low toxicity, and is not very soluble in water. In contrast, Cr(VI) is more toxic and can be harmful to health, affecting the respiratory, gastrointestinal, and immune systems, as well as the kidneys, liver, blood, and skin.
Chromium forms a complex with hemoglobin called chromodulin, which helps regulate insulin sensitivity and glucose metabolism in the body.
For example, chromium deficiency can impair the function of chromodulin and lead to insulin resistance, which can increase the risk of developing type 2 diabetes.
