NTDT Metabolism

Terms in this set (35)

Metabolism
all of the life-sustaining chemical reactions that occur in living organisms that convert one molecule to another molecule.
Energy
the capacity to do work

Four Kinds:
Heat - Maintains Body Temperature

Mechanical - Moves muscles

Electrical - Sends nerve impulses

Chemical - Stored energy to power cells
Wheres the site of metabolic reactions?
In the cells
Anabolic
Building up
Glucose + Glucose = Glycogen
3 FA + Glycerol = Triglyceride
Gly + Ala + Leu = Tripeptide
Energy requiring
Catabolic
• Breaking down
• Glycogen = glucose + glucose
• Triglyceride = 3 FA + glycerol
• Tripeptide = Gly + Ala + Leu
• Energy releasing
Energy metabolism
All the ways the body obtains and uses energy from food
Adenosine Tri-Phosphate: (ATP)
High energy compound
Energy is releases when high energy phosphate bond in ATP is broken
• ATP is released during the breakdown of glucose, fatty acids and amino acids
• This energy is used to do most of the body's work
What are the two helpers in metabolic reaction
Enzymes and coenzymes
Enzymes
Facilitators of metabolic reactions
Coenzymes
• Organic
• Associate with enzymes
• Without coenzyme, an enzyme cannot function
Digestion: Carbs to
Glucose (and other monosaccharides)
Digestion: Fats to
glycerol and fatty acids
Digestion: Proteins to
Amino acids
Catabolism
Break bonds
So glucose, glycerol, amino acids and fatty acids
to carbon, nitrogen, oxygen and hydrogen
Cellular respiration
Cellular respiration is the process by which the energy stored in fuels is transferred to ATP by a series of enzyme-catalyzed reactions.
