What is the process by which the body converts food into energy?

  1. Metabolism

  2. Digestion

  3. Absorption

  4. Excretion


Correct Option: A
Explanation:

Metabolism is the process by which the body converts food into energy.

What are the two main types of metabolism?

  1. Catabolism and Anabolism

  2. Glycolysis and Gluconeogenesis

  3. Krebs Cycle and Electron Transport Chain

  4. Oxidative Phosphorylation and Photophosphorylation


Correct Option: A
Explanation:

Catabolism is the process by which the body breaks down food into smaller molecules, releasing energy. Anabolism is the process by which the body uses these smaller molecules to build new molecules, such as proteins and carbohydrates.

What is the role of ATP in metabolism?

  1. It is the body's main energy currency.

  2. It is a coenzyme in many metabolic reactions.

  3. It is a hormone that regulates metabolism.

  4. It is a neurotransmitter that affects appetite and energy expenditure.


Correct Option: A
Explanation:

ATP is the body's main energy currency. It is used to power all of the body's cells.

What is the role of the Krebs Cycle in metabolism?

  1. It is the first stage of cellular respiration.

  2. It is the second stage of cellular respiration.

  3. It is the third stage of cellular respiration.

  4. It is the final stage of cellular respiration.


Correct Option: B
Explanation:

The Krebs Cycle is the second stage of cellular respiration. It is a series of chemical reactions that convert acetyl-CoA into carbon dioxide and energy.

What is the role of the Electron Transport Chain in metabolism?

  1. It is the first stage of cellular respiration.

  2. It is the second stage of cellular respiration.

  3. It is the third stage of cellular respiration.

  4. It is the final stage of cellular respiration.


Correct Option: C
Explanation:

The Electron Transport Chain is the third stage of cellular respiration. It is a series of chemical reactions that use the energy from NADH and FADH2 to pump protons across a membrane, creating a gradient that drives the synthesis of ATP.

What is the role of Oxidative Phosphorylation in metabolism?

  1. It is the first stage of cellular respiration.

  2. It is the second stage of cellular respiration.

  3. It is the third stage of cellular respiration.

  4. It is the final stage of cellular respiration.


Correct Option: D
Explanation:

Oxidative Phosphorylation is the final stage of cellular respiration. It is a series of chemical reactions that use the energy from the proton gradient created by the Electron Transport Chain to synthesize ATP.

What is the difference between basal metabolic rate (BMR) and resting metabolic rate (RMR)?

  1. BMR is the amount of energy the body needs to function at rest, while RMR is the amount of energy the body needs to function during light activity.

  2. BMR is the amount of energy the body needs to function during light activity, while RMR is the amount of energy the body needs to function at rest.

  3. BMR is the amount of energy the body needs to function during moderate activity, while RMR is the amount of energy the body needs to function during light activity.

  4. BMR is the amount of energy the body needs to function during heavy activity, while RMR is the amount of energy the body needs to function during moderate activity.


Correct Option: A
Explanation:

BMR is the amount of energy the body needs to function at rest, while RMR is the amount of energy the body needs to function during light activity.

What are the factors that affect BMR?

  1. Age, gender, muscle mass, and activity level.

  2. Age, gender, body fat percentage, and activity level.

  3. Age, gender, height, and weight.

  4. Age, gender, weight, and muscle mass.


Correct Option: A
Explanation:

The factors that affect BMR are age, gender, muscle mass, and activity level.

What are the factors that affect RMR?

  1. Age, gender, muscle mass, and activity level.

  2. Age, gender, body fat percentage, and activity level.

  3. Age, gender, height, and weight.

  4. Age, gender, weight, and muscle mass.


Correct Option: B
Explanation:

The factors that affect RMR are age, gender, body fat percentage, and activity level.

What is the relationship between metabolism and energy balance?

  1. Metabolism is the process by which the body converts food into energy, while energy balance is the relationship between the amount of energy the body takes in and the amount of energy the body expends.

  2. Metabolism is the process by which the body expends energy, while energy balance is the relationship between the amount of energy the body takes in and the amount of energy the body stores.

  3. Metabolism is the process by which the body stores energy, while energy balance is the relationship between the amount of energy the body takes in and the amount of energy the body expends.

  4. Metabolism is the process by which the body takes in energy, while energy balance is the relationship between the amount of energy the body expends and the amount of energy the body stores.


Correct Option: A
Explanation:

Metabolism is the process by which the body converts food into energy, while energy balance is the relationship between the amount of energy the body takes in and the amount of energy the body expends.

What is a positive energy balance?

  1. When the body takes in more energy than it expends.

  2. When the body expends more energy than it takes in.

  3. When the body takes in and expends the same amount of energy.

  4. When the body stores more energy than it expends.


Correct Option: A
Explanation:

A positive energy balance is when the body takes in more energy than it expends.

What is a negative energy balance?

  1. When the body takes in more energy than it expends.

  2. When the body expends more energy than it takes in.

  3. When the body takes in and expends the same amount of energy.

  4. When the body stores more energy than it expends.


Correct Option: B
Explanation:

A negative energy balance is when the body expends more energy than it takes in.

What are the consequences of a positive energy balance?

  1. Weight gain, increased risk of obesity, and chronic diseases.

  2. Weight loss, decreased risk of obesity, and chronic diseases.

  3. No change in weight, no change in risk of obesity, and no change in risk of chronic diseases.

  4. Weight gain, decreased risk of obesity, and increased risk of chronic diseases.


Correct Option: A
Explanation:

The consequences of a positive energy balance are weight gain, increased risk of obesity, and chronic diseases.

What are the consequences of a negative energy balance?

  1. Weight loss, decreased risk of obesity, and chronic diseases.

  2. Weight gain, increased risk of obesity, and chronic diseases.

  3. No change in weight, no change in risk of obesity, and no change in risk of chronic diseases.

  4. Weight gain, decreased risk of obesity, and increased risk of chronic diseases.


Correct Option: A
Explanation:

The consequences of a negative energy balance are weight loss, decreased risk of obesity, and chronic diseases.

How can you achieve a healthy energy balance?

  1. Eat a healthy diet, get regular exercise, and get enough sleep.

  2. Eat a high-fat diet, get no exercise, and get too much sleep.

  3. Eat a high-carbohydrate diet, get no exercise, and get too much sleep.

  4. Eat a high-protein diet, get no exercise, and get too much sleep.
