Metabolism Flashcards
Metabolism originates from the Greek word _
Change
Metabolism is collective term for all _ that occur within an organism to keep it alive

Processes
All organisms are constantly carrying out thousands of _ to stay alive
Metabolic processes
Metabolic processes produce _
Waste
Amount of energy organism needs to perform metabolic processes called _
Metabolic rate
Metabolic rate can be measured in
Calories per day (kcal/day)
Human’s calories per day (kcal/day) (range)
1,900
2,300
Amino acids are used to
Build proteins for cell maintenance
Products of metabolic reactions that cannot be used or stored are called _
Byproducts
Breaking down molecules such as food, into smaller molecules releases _
Energy
Muscles use an energy-carrying molecule called _ energy to contract
ATP
Amino acids circulate through bloodstream and _
Build up proteins that can be used for growth
Excess body heat lost to _
Air
_ is needed to metabolize food
Oxygen
Proteins used in (2)
Cell division
Cell repair
Proteins used in strained muscle and
Wounded tissue
Egestion is passing out _ as feces
Undigested food
Some metabolic processes require energy while others _
Release it
There are two main types of _
Reactions
First type of reaction building complex molecules out of ()
Simpler units (anabolism)
Second type of reaction breaking molecules into smaller units is called _
Catabolism
Catabolism releases _
Energy
Anabolism consumes energy while _
Linking simple molecules into simple ones
Example of anabolism is gluconeogenesis in which liver and kidneys _
Produce glucose from non-carbohydrate sources
