enzymes Flashcards
what is a biological catalyst?
not living but found in living organisms (a type of protein)
what do enzymes do?
they break down nutrients into small, soluble molecules that can be absorbed into the blood stream
what are the three types of enzymes?
amylase, lipase and protase
what does amylase break down?
carbohydrates
what does lipase break down?
lipids
what does protease break down?
proteins
what do carbohydrates get broken down into?
sugars
what do lipids get broken down into?
fatty acids+ glyceol
what do proteins get broken down into?
stomach+small intestine
what are the factors that can effect enzymes?
pH
temperature
concentration
what is the optimum temperature of enzymes?
around 37.5 degree celsius
what happens to the protein structure of enzymes if the temp in above optimum?
the protein structure is affected. the long amino acid chains unravel , and as a result the shape site change. if this occurs we say the enzyme has been denatured
what makes up a protein molecule?
a long chain of amino acids
what makes up a starch molecule?
a long chain of glucose
