STUDY
PLAY
All chemical reactions that occur in the body are.
metabolic processes
what are the two types of metabolic reactions?
Anabolism and Catabolism
anabolism
builds large molecules from simple ones; requires energy
catabolism
Process of breaking down complex materials (foods) to form simpler substances and release energy.
anabolism provides for what two things?
Cellular growth and repair
What anabolic process is used to make polysaccharides, triglycerides and proteins.
dehydration synthesis
What process is used to decompose carbohydrates, lipid and proteins?
catobolic process
What is used to split the substances during the catobolic process?
Water
enzymes
protein substances that speed up chemical reactions.
cofactors
A non-protein component that makes some enzymes active.
Coenzymes
organic molecules that act as cofactors example vitamins
What factors alter enzymes?
Heat, Radiation, Electricity, Chemicals, Changes in PH
What regulates the metabolic pathways
negative feedback adn limited number of regulatory enzymes
Examples of enzymes
Sucrase, lactase, protease, lipase
dehydration syntheisis produces what?
produces water
enzymes are ---------specific.
substrate
what determines the active site of substrate?
shape
What do enzymes do?
control the rate of metabolic reactions
Enzymes jave the suffix
--ase
enzyme action-metabolic pathways
each new substrate is the product of the previous reaction
