Metabolic rate is relatively low in:
a. Youth
b. Physical exercise
c. Old age
d. Fever

검증된 단계별 안내

Understand the concept of metabolic rate: Metabolic rate refers to the amount of energy expended by the body to maintain basic physiological functions such as breathing, circulation, and cellular processes. It can be influenced by factors such as age, physical activity, and health conditions.

Analyze the options provided: Youth, physical exercise, old age, and fever. Consider how each factor affects the metabolic rate based on physiological principles.

Recall that metabolic rate tends to be higher during physical exercise and fever due to increased energy demands for muscle activity and immune responses, respectively.

Consider the impact of age: In youth, metabolic rate is generally higher due to growth and development processes. In old age, metabolic rate tends to decrease due to reduced muscle mass and slower physiological functions.

Conclude that the metabolic rate is relatively low in old age compared to the other options provided, based on the physiological changes associated with aging.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Metabolic Rate

Metabolic rate refers to the rate at which the body converts food into energy. It is influenced by various factors including age, physical activity, and overall health. A higher metabolic rate means the body burns calories faster, while a lower rate indicates fewer calories are burned, which can affect weight and energy levels.

Age and Metabolism

As individuals age, their metabolic rate typically decreases due to a loss of muscle mass and hormonal changes. This decline can lead to weight gain if dietary habits remain unchanged. Understanding how age affects metabolism is crucial for managing health and weight in older adults.

Impact of Physical Activity

Physical activity significantly boosts metabolic rate, as exercise increases energy expenditure both during and after workouts. Regular exercise can help counteract the natural decline in metabolism associated with aging, making it an essential component of a healthy lifestyle for maintaining weight and overall health.
