    The hormone that helps regulate the amoount of glucose in the blood stream is _______________.

    • Glycogen

    • Insullin

    • Ketones

    • Thyroxin

    Correct Answer
    A. Insullin
    Explanation
    Insulin is the hormone that helps regulate the amount of glucose in the bloodstream. It is produced by the pancreas and plays a crucial role in maintaining normal blood sugar levels. Insulin allows glucose to enter cells, where it is used for energy or stored as glycogen. Without insulin, glucose cannot be properly absorbed by cells, leading to high blood sugar levels, which can result in diabetes. Ketones are byproducts of fat breakdown, glycogen is a stored form of glucose, and thyroxin is a hormone that regulates metabolism.
