DNA
DEOXYRIBONUCLEIC ACID
2 of 22
ENZYMES
ADVANATGES: USING LOWER TEMP AND PRESSURES MEANS LOWER COST AND SAVES ENERGY DISADVANTAGES: CAN BE DENATURED ( DON'T WORK ANYMORE) BY EVEN A SMALL RISE IN TEMP, ENZYMES CAN BE EXPESIVE (£) TO PRODUCE.

MEIOSIS
MAKES NEW SEX CELLS- GAMETS ARE SEX CELLS!! EG, SPERM CELL/EGG CELLS THIS TYPE OF CELL DIVISION IS MEIOSIS.

ATOMS, COMPOUNDS AND ISOTOPES
ATOMIC NUMBER ( N U M B E R O F P R O T O N S) MASS NO ( T O T A L N U M B E R O F P R O T O N S A N D N E U T R O N S)
5 of 22
IONIC BONDING
IN IONIC BONDING ATOMS LOSE OR GAIN ELECTRONS TO FORM IONS(POSTIVE/NEGATIVE CHARGE) OPPOSTIE CHARGE IONS ARE ATTRACTED TO EACH OTHER TO FORM IONIC BONDS .
6 of 22
HYDROGEN AND CHLORINE
HYDRO ATOMS HAVE 1 ELECTRON AND NEED ONE MORE TO COMPLETE FIRST SHELL ( 8 IS A FULL SHELL) CHLORINE ATOMS NEED 1 MORE TO FILL OUTER SHELL!
7 of 22
POLYMERS
THERMOSOFTENING POLY ARE MADE UP OF LOTS OF TANGLED CHAINS OF POLYMERS. THESE SLIDE OVER EACH OTHER AND ARE E A S Y T O M E L T!!! THERMOSETTING- CROSSED LINKS BETWEEN CHAINS OF POLYMERS, THESE HOLD THE CHAINS TOGETHER IN A S O L I D STRUCTURE
8 of 22
RATE OF REACTION
TEMPERATURE CONCENTRAITON CATALYSTS SURFACE AREA OF SOLIDS
9 of 22
COLLISONS
TEMP INCREASED PARTICLES MOVE QUICKER ( IF MOVED QUICKER THEY COLLIDE OFTEN)
10 of 22
CATALYSTS
MANY REACTIONS CAN BE SPEEDED UP BY ADDING A CATALYST-DIFFERENT REACTIONS NEED DIFF CATALSYST ( ENZYMES IS A CATALYST)
11 of 22
EXOTHERMIC AND ENDOTHERMIC
EXO- GIVES ENERGY TO ITS SURROUNDINGS ENDO- TAKES IN ENREGY FROM SURROUNDINGS
12 of 22
PH SCALE
ACID HAS A PH LESS THAN 7!! ACIDS FORM HYDROGEN IONS ( H+) IN WATER, BASE HAS PH BIGGER THAN 7! ALKALINE BASE DISSOLVES IN WATER!
13 of 22
ACIDS REACTING WITH METALS
ACID + METAL ----> SALT + HYDROGEN
14 of 22
ACCELERATION AND VELOCITY
ACCELERATION =CHANGE IN VELOCITY/ TIME TAKEN ( DIVIDED) CHANGE IN VELOCITY THEN - INITIAL VELOCITY FROM FINAL VELOCITY
15 of 22
FORCES AND ACCELERATION
A NON ZERO RESULTANT FORCE PRODUCES AN ACCELERATION - F=MA OR A=F/m
16 of 22
KINETIC ENERGY
MOVING CAR= LOTS OF KINETIC ENERGY. TO STOP OR SLOW DOWN A CAR THIS KINETIC ENERGY NEEDS TO BE TRANSFERED INTO OTHER TYPES OF ENERGY, WHEN THE BRAKES ARE USED WORK IS DONE BY THE FRICTION BETWEEN THE WHEELS AND THE BRAKE PADS, KINE-HEAT
17 of 22
POWER!!!!!!!!!!!!!!!!!!!!
POWER= WORK DONE ( OR ENERGY TRANSFERED/ TIME TAKEN) OR P=E/t THE PROPER UNIT OF POWER IS WATTS 1W=1JOULE OF ENERGY TRANSFERED PER SECOND
18 of 22
CURRENT AND POTENTIAL DIFFERENCE
CURRENT=ELECTRIC CHARGE AROUND THE CIRCUIT POTENTIAL DIFFERNCE IS DRIVING FORCE THAT PUSHES THE CURRENT ROUND. RESITANCE IS ANYTHING IN CIRCUIT THAT SLOWS DOWN FLOW
19 of 22
NUCLEAR FISSION
THIS IS WHERE AN ATOMIC NUCLEUS SPLITS NUCLEAR FISSION REACTIONS ARE USEFLUL AS THEY RELEASE LOTS OF ENERGY
20 of 22
NUCLEAR FUSION
TWO LIGHT NUCLEI ( SUCH AS HYDROGEN) JOIN TO CREATE NUCLEUS THIS IS NUCLEAR FUSION. IT RELEASES LOTS OF ENERGY ALL ENERGY RELASEAD IN STARS COMES FROM FUSION!

PHOTOSYNTHESIS
CARBON DIOXIDE + WATER SUNLIGHT( OVER CHLOROPHYLL) -----> GLUCOSE + OXYGEN
