enzymes Flashcards
what are enzymes ?
- enzymes are catalyst produced by living things
what do living things have inside them that goes on the whole time ?
- chemical reactions
what do living things produce and what do they act as ?
- produce enzymes that act as biological catalyst
what is a catalyst ?
- a substance that increases the speed of a reaction without being changed or used up in the reaction
enzymes are proteins , what are they made up of ?
- chains of amino acids
as well as catalyst , what else do proteins act as
- structural components of tissues e.g. muscles hormones and anitbodie s
what do enzymes have so they can catalyse recations
- they have special shapes
what is the process of lock and key hypothesis ?
- an enzyme catalyse with a section out called an active site , part out is a substance
- substance called substrate goes in to the enzymes to be a full shape -> then allows the reaction to happen
what are the 2 types of enzymes relations ?
- catabolic
- anabolic
what does it mean when a enzyme has become denatured ?
- it has lost some of its original properties
what reaction in enzyme is this (check link) - https://biochem80p.files.wordpress.com/2014/03/enzyme-working-mechanism.jpg
lock and key hypothesis
true or false ?
changing the rate of temperature changes doesn’t change the rate of an enzyme- catalysed reaction
false
it does change the rate of the enzymes reaction
what happens if the enzyme gets to hot ?
- some of the bonds holding the enzyme together break then leading to destroy the enzymes special shape
= becoming denatured
what temperature do enzymes in the human body work best at ?
- 37 c
what can effect enzymes ?
- increase of temperature
- increase of Ph
