They control cell reactions, biological cataylsts, speeds up a reaction, made of protiens, reduce need for high temperatures
1 of 7
How are enzymes specific?
substrate is changes in the reaction, active site joins onto substrate, protiens made
2 of 7
What is genetic engineering?
move genes from one organism to another, produce biological products.
3 of 7
What are the advantages of Genetic engineering?
produce organisms with new and useful features, however mide had unexpected harmful effects, if they become pathogenic
4 of 7
What are the stages of genetic engineering?
gene responible for desirable characteristic is selected, cut from DNA using enzymes, gene insterted into organism, organism replicates

What are the properties of diamond?
lustrous (sparkly), colourless, four covelent bonds, really hard, covelent bonds take a lot of energy to break (high melting point), doesnt conduct electricity, no free electrons
6 of 7
What are the properties of graphite?
black and opaque, three covelent bonds, lubricating material, high melting point, bonds need lots of energy to break, delocalised electrons, conduct electricity
