Enzymes Flashcards
what is the function of enzymes
to break down large, insoluble molecules into small, soluble molecules
give two examples of where enzymes can be found
digestive system
washing powders
what are enzymes also known as
biological catalysts
define catalysts
molecules that speed up a chemical reaction without being changed
are catalysts reusable and made of proteins
yes
give two examples of chemical reactions where catalysts are used
respiration
photosynthesis
what do enzymes have and what are they complimentary to
enzymes have an active site which is complimentary to substrates to form an enzyme substrate complex
what happens when the enzyme substrate complex is formed
the substrate is broke into two soluble molecules which makes the products
name the three digestive enzymes
lipase
protease
amylase / carbohydrase
what does lipase break down and what is the product
lipase breaks down fat (lipids) into glycerol
what does protease break down and what are the products
protesse breaks down proteins into amino acids
what does amylase break down and what are the products
amylase breaks down starch/ carbohydrates into glucose
can protease break down starch and why
protease cannot break down starch because it’s active site does not match starch’s substrate
where is amylase made and where does it work
amylase is made in the salivary glands and pancreas
it works in the mouth and small intenstine
where is lipase made and where does it work
lipase is made in the pancreas and small intestines
it works in the small intestine
where is protease made and where does it work
protease is made in the stomach, small intestine and the pancreas
it works in the stomach and small intestine
define rate of reactions
the speed at which a chemical reaction happens
what are the 2 things a rate of reaction is measured by
the time taken for the reactant / substance to be used up
the time it takes for the product to be made
what is the equation for rate of reaction (gradient)
