- B2 Revision
- cells
- all have neucleas
- except red blood cells
- bacteria cells
- no nucleus
- chromosomes control the cells
- reproduction
- all have membrane
- plants have cell walls
- bacteria cells
- no nucleus
- chromosomes control the cells
- reproduction
- all have neucleas
- DNA
- double helix
- Adenine-Thymine
- Guanine-Cytosine
- Building Blocks of life
- Protein Structure
- DNA
- double helix
- Adenine-Thymine
- Guanine-Cytosine
- Building Blocks of life
- Enzymes
- catalysts produced by living things
- different chemical reactions happening all the time
- easy catalyst caused by heat rising
- catalysts produced by living things
- what works with internal reactions
- protease-protein
- Amylase -breaks down starch
- protease-protein
- have different shapes to they can catalyse reactions easier
- enzyme controlled reaction
- heat has to be right otherwise
- if to cold it wont work properly
- if its to warm the enzyme will break apart and will die
- heat has to be right otherwise

- cloning
- produces clones that are genetically identical --> jango fett/boba fett
- neucleus is taken from an adult cell containing the full number of chromosomes
- the neucleas is then entered into an egg cell of a female of that specias which is devoid of its egg
- the egg cell then is electrically stimulated thus brining it to life(Frankenstein)
- when it grows into a bundle of cells its reimplanted into the womb of the female and grows like a normal child
- excersise and respiration
- breath more when ecersising
- cardiac output =HR*Stroke volume
- Photosynthisis
- plants making their own food
- it happens in all green plants
- leaves are full of stomata
- carbon dioxide +water --> glucose+oxygen
- the rate of photosynthesis
- light needs to be right
- the amount of carbon dioxide has to be right
- the peak tepreature has to be around 40 degreees centegrade
- cells
