Epidermal cells become keratinized, meaning that they.

A. They give the body essential amino acids: Carbohydrates do not provide amino acids; proteins are the primary source of amino acids.

B. They give the body quick energy: Simple carbohydrates (monosaccharides) provide quick energy as they are rapidly absorbed and metabolized.

C. They give the body nonessential amino acids: Carbohydrates do not contribute to amino acid supply; nonessential amino acids can be synthesized by the body.

D. They give the body sustainable energy: Complex carbohydrates, such as whole grains and fiber, provide long-lasting energy as they take longer to break down into glucose.

A. Hypernatremia: Hypernatremia refers to high sodium levels, which are not directly related to impaired glucose metabolism.

B. Hyperglycemia: Aging reduces insulin sensitivity and pancreatic function, leading to higher blood glucose levels, or hyperglycemia, which is a risk factor for diabetes mellitus.

C. Hypoglycemia: Aging-related insulin resistance typically results in elevated glucose levels (hyperglycemia), not low blood sugar (hypoglycemia).

D. Hyperkalemia: Hyperkalemia is an excess of potassium in the blood, which is not directly linked to impaired glucose metabolism.
