검증된 단계별 안내1
Step 1: Understand the concept of energy-yielding nutrients. Energy-yielding nutrients are those that can be metabolized by the human body to produce ATP, the primary energy currency of cells. These include carbohydrates, proteins, and fats.
Step 2: Analyze each option provided in the question. Carbohydrates are a primary energy source, as they are broken down into glucose, which is metabolized through glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP.
Step 3: Consider the role of minerals. Minerals do not yield energy directly; instead, they serve as cofactors for enzymatic reactions and structural components in the body.
Step 4: Evaluate water's role. Water is essential for maintaining cellular homeostasis and facilitating biochemical reactions, but it does not provide energy as it is not metabolized.
Step 5: Assess vitamins. Vitamins are organic compounds that act as coenzymes or precursors for enzymatic reactions, but they do not yield energy directly when metabolized.
