Which of the following is often found in individuals who are active and eating a healthy diet?
A
Low energy levels
B
Decreased cellular respiration
C
High metabolic rate
D
Reduced enzyme activity
Verified step by step guidance1
Step 1: Understand the concept of metabolic rate. Metabolic rate refers to the rate at which the body converts food into energy through cellular processes, including cellular respiration. A high metabolic rate indicates efficient energy production and utilization.
Step 2: Relate metabolic rate to activity levels and diet. Individuals who are active and consume a healthy diet typically have a higher metabolic rate because their bodies require more energy to sustain physical activity and maintain optimal cellular functions.
Step 3: Examine the incorrect options. Low energy levels and decreased cellular respiration are typically associated with inactivity or poor nutrition, not with active individuals eating a healthy diet. Reduced enzyme activity would also hinder metabolic processes, which is contrary to the scenario described.
Step 4: Connect cellular respiration to metabolic rate. Cellular respiration is the process by which cells generate ATP (energy) from nutrients. A healthy diet provides the necessary nutrients, and physical activity stimulates cellular respiration, contributing to a high metabolic rate.
Step 5: Conclude that the correct answer is 'High metabolic rate,' as it aligns with the physiological characteristics of active individuals consuming a healthy diet.
