Intro to metabolism
Chemical reactions in the body's cells that convert food into energy
What is metabolism?
Also called simple sugars
What is monosaccharide and disaccharide?
Carbohydrates must be broken down into this molecule in order to initiate metabolism
Glucose
Energy expended for everything we do that is not sleeping, eating, or exercise
What is NEAT?
A ranking or numerical system that denotes the ratio of the energy expenditure of an activity relative to sitting quietly at rest.
What are metabolic equivalents (METs)?
When energy intake is less than energy expenditure
What is negative energy balance?
The first stage of cellular respiration
What is Glycolysis?
The building blocks of triglycerides
Error rate when estimating RMR using equations?
What is 10-36%?
A list of physical activity intensities in METs
The Compendium of Physical Activities
The number of calories in 1 gram of CHO, PRO, and FAT
The whole process of cellular respiration produces this many ATP per 1 glucose molecule
What is 28-32 ATP?
The thermic effect of Fats
What is 0-3%?
Major determinant of NEAT?
What is occupation?
A person ate a meal containing 20g of CHO, 10g of PRO, and 5g of FAT. How many calories came from fat?
What is 45 kcals?
Energy currency of the cell
What is ATP?
The building blocks of proteins
What are amino acids?
The process of breaking down fats in your body into smaller components, such as fatty acids and glycerol, so they can be used for energy.
What is lipolysis?
Main contributor to RMR
What is muscle?
Known as the hunger hormone
Minimum number of calories needed at rest and is measured under strict lab conditions
What is Basal Metabolic Rate (BMR)?
Type of amino acid that cannot be synthesized by the body.
What is essential?
Resting metabolic rate (RMR) accounts for this percentage of daily energy expenditure.
What is 60-70%?
This component contributes the least amount of someones TDEE
What is the Thermic Effect of Food (TEF)?
Known as the satiety hormone
What is leptin?
