Flashcard 1
Q: What is metabolism?
A: Metabolism is the body's "engine" that keeps you alive and gives you energy through chemical reactions.
Flashcard 2
Q: What are the two types of metabolism?
A: Anabolism (building larger molecules) and Catabolism (breaking down molecules for energy).
Flashcard 3
Q: What is anabolism?
A: Anabolism is the "building" part of metabolism, where smaller molecules combine to make bigger ones, like glucose turning into glycogen.
Flashcard 4
Q: What is catabolism?
A: Catabolism is the "breaking down" part of metabolism, where large molecules are broken down to release energy.
Flashcard 5
Q: What are macronutrients?
A: Macronutrients are nutrients that provide energy: carbohydrates, fats, and proteins.
Flashcard 6
Q: What do carbohydrates do in the body?
A: Carbohydrates are broken down into glucose, providing quick energy, and any extra is stored as glycogen.
Flashcard 7
Q: How does the body use fats for energy?
A: Fats are broken down slowly for long-term energy and stored in the body if there's extra.
Flashcard 8
Q: Why are proteins important, and does the body store them?
A: Proteins help build muscles and structures; they aren’t stored and are used up quickly.
Flashcard 9
Q: What is glycolysis?
A: Glycolysis is the process of breaking down glucose for energy, producing either water and carbon dioxide or lactate if oxygen is low.
Flashcard 10
Q: What is glycogenesis?
A: Glycogenesis is the process of turning extra glucose into glycogen for storage in the liver and muscles.
Flashcard 11
Q: What is glycogenolysis?
A: Glycogenolysis is the process of turning stored glycogen back into glucose when the body needs energy.
Flashcard 12
Q: What is lipolysis?
A: Lipolysis is the process of breaking down stored fat into fatty acids, which can then be used for energy.
Flashcard 13
Q: What is b-oxidation?
A: b-oxidation is the process of breaking down fatty acids in the mitochondria to create energy.
Flashcard 14
Q: What does insulin do in energy metabolism?
A: Insulin helps move glucose into cells for energy, stores extra as glycogen, and promotes fat and protein storage.
Flashcard 15
Q: What does glucagon do in energy metabolism?
A: Glucagon raises blood glucose by breaking down glycogen and promoting fat breakdown for energy when food is low.
Flashcard 16
Q: What happens during short bursts of exercise in terms of energy?
A: Muscles use energy from creatine phosphate for quick bursts.
Flashcard 17
Q: What energy process is used in moderate exercise?
A: Muscles first use glucose from glycolysis, then switch to an oxygen-rich way to make energy.
