POPULATIONS EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
the "breakdown" phase where larger molecules (like carbs, fasts and proteins)
are broken down into smaller units to release energy
Catabolism
_____________ are broken down into glucose, which is used to produce ____, the
primary energy currency of cells
CARBOHYDRATES are broken down into glucose, which is used to produce ATP, the
primary energy currency of cells
_____ are broken down into fatty acids, providing a significant energy source,
especially during long-duration activities
FATS
_________ can be broken down into amino acids, used primarily when other
energy sources are depleted
PROTEINS
The "building" phase, where smaller molecules are synthesized into larger
molecule
ANABOLISM
Anabolic Processes require energy, usually in the form of ATP to: (2)
,- Build muscle tissue and other body structures
- Store nutrients in forms like glycogen (for quick energy( and triglycerides (for long-term
fat storage)
Metabolic processes are regulated by _________ and ________, which adjust
metabolic rates based on factors like activity level, diet, age, and overall health
Metabolic processes are regulated by ENZYMES and HORMONES, which adjust
metabolic rates based on factors like activity level, diet, age, and overall health
Together, catabolism and anabolism balance energy use and storage,
supporting....(3)
- growth
- repair
- overall health
Body's preferred quick energy source, especially during high intensity activity
Carbohydrates (mainly glucose)
Carbohydrates are broken down into ________, which goes through _________,
producing ATP quickly
Carbohydrates are broken down into GLUCOSE, which goes through GLYCOLYSIS,
producing ATP quickly
Glucose is stored in the liver and muscles as ________, a backup energy source
when blood glucose levels are low
GLYCOGEN
The body's long-term energy reserve and a major fuel source during low to
moderate intensity activities
, FATS (mainly fatty acids)
Fats are broken down into _______ ______, which are used in mitochondria to
produce ATP in a slow process called _____-___________. This process
(requires/doesn't require) oxygen and is slower but produces (more/less) energy
than carbohydrate breakdown.
Fats are broken down into FATTY ACIDS, which are used in mitochondria to produce
ATP in a slow process called BETA-OXIDATION. This process REQUIRES oxygen and
is slower but produces MORE energy than carbohydrate breakdown.
Fats are stored as _________ in fat cells
TRIGLYCERIDES
True or False: Carbs are a highly energy-dense substrate, providing more energy
per gram than fats
FALSE, fats are highly energy dense and produce more energy per gram than carbs
typically used as a backup energy source, especially when carbs and fat reserves
are low (e.g., during prolonged fasting or extreme exercise)
Proteins
Proteins are broken down into _______ ______, which can be converted into
________ or used directly for energy, though this is less efficient and can
compromise muscle tissue and other protein-dependent functions.
Proteins are broken down into AMINO ACIDS, which can be converted into GLUCOSE
or used directly for energy, though this is less efficient and can compromise muscle
tissue and other protein-dependent functions.
