Proteins and Mutations Flashcards
what are proteins made of?
a chain of animo acids
what are structural proteins used for?
to build cells and tissue (Cologne)
what are hormone (proteins) used for?
they carry messages to control chemical reactions in the body (insulin in the bloodstream)
what do carrier proteins do?
carry substances around the body (haemoglobin that carries oxygen)
what is an enzyme?
a protein that controls and speeds up chemical reactions in the body.
how does each type of protein have its own shape and function?
because the
how does each type of protein have its own shape and function?
because the coding puts the chain of amino acids in a certain order
how does each type of protein have its own shape and function?
because the coding puts the chain of amino acids in a certain order
why are enzymes called biological catalysts
because they speed up reactions.
which reactions do enzymes catalyse?
respiration, photosynthesis, protein synthesis
what is an active site?
the part of the enzyme (on the surface that attaches to substrates
are all active sites different?
yes, each type of enzyme has its own active site to fit the substrate the enzyme needs to attach to
what is the lock and key process?
the enzyme attaches (via active site) to a substrate creating a substrate complex, the substrate splits into new products and detaches
what is the lock and key process?
the enzyme attaches (via active site) to a substrate creating a substrate complex, the substrate splits into new products and detaches
why do enzymes work best at a certain ph and temperature?
because anything lower slows the reaction down, anything more and it becomes misshapen
