Metabolism
the sum of all chemical reactions in the body
what are the two types of metabolism
catabolism and anabolism
catabolism
BREAKdown - EXergonic
what does exergonic mean
release energy
anabolism
BUILDing - ENDergonic
what does endergonic mean
consumes energy
what is the 1st law of thermodynamics
the law of conservation of energy
law of conservation of energy
energy can be neither created or destroyed, only converted
ATP
useful form of chemical energy in our bodies
What are the two types of energy transfer
oxidation and reduction
oxidation
involves the REMOVAL of electrons from an atom or molecule
reduction
involves the addition of electrons to an atom or molecule
what is the main energy transfer rule
oxidation and reduction must ALWAYS be COUPLED
Redox reactions
if one is reduced the other is oxidized
what is another term for oxidation
DEHYDROGENATION
What is another word for reduction
HYDROGENATION
What are the main macronutrients
carbohydrates, lipids and proteins
glycolysis
glucose breakdown to produce ATP
What type of metabolism reaction does glycolysis experience
CATABOLIC
gluconeogenesis
formation of glucose from lipid or protein
what type of metabolic reaction does gluconeogenesis experience?
ANABOLIC
glycogenolysis
breakdown of glycogen into glucose
what type of metabolic reaction does glycogenolysis experience?
CATABOLIC
glycogenesis
synthesis of glycogen from glucose
