Question

Name the factors on which the energy requirement of a person dependsa person depends

Answer 1

Metabolism consists of the sum of enzyme-catalyzed reactions occurring within a living organism. It consists of anabolic and catabolic reactions, which are building up and breaking down reactions respectively. The rate at which these reactions occur depends on the organism's behavior and size.

Answer and Explanation:

A person's Basal Metabolic Rate (BMR) is the daily amount of energy their body requires if at rest in a temperate environment. An average person's BMR accounts for around 70% of their total daily energy expenditure, while physical activity accounts for 20% and digestion accounts for the remaining 10%. Therefore, an individual with higher body mass will have a higher energy requirement/basal metabolic rate as there are more cells which need energy. Furthermore, those individuals who are more physically active will have a higher energy requirement as they need more energy to perform said physical activity.
