Idina claims she has a good metabolism. What does this most likely mean for Idina?

• A. Her body stores more fat than usual after eating.
• B. She requires less oxygen for cellular respiration than most people.
• C. Her body efficiently converts food into energy and she may burn calories faster than average.
• D. She has a higher than normal body temperature at all times.

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the term 'metabolism' in biology. Metabolism refers to all the chemical reactions in the body that convert food into energy and support life processes, including cellular respiration, growth, and repair.
2. Step 2: Recognize that a 'good metabolism' typically implies efficient energy conversion. This means the body processes food effectively to produce energy and may burn calories faster than average.
3. Step 3: Evaluate the options provided in the problem. For example, storing more fat after eating is not indicative of a good metabolism, as it suggests inefficient energy use.
4. Step 4: Consider the role of oxygen in cellular respiration. While oxygen is essential for energy production, requiring less oxygen does not necessarily correlate with a 'good metabolism.'
5. Step 5: Conclude that the correct interpretation of 'good metabolism' aligns with the idea that Idina's body efficiently converts food into energy, supporting faster calorie burning and overall energy use.
