practise
respiration
aerobic - uses oxygen
anaerobic - doesn’t use oxygen
both are exothermic reactions
aerobic - oxygen + glucose —> carbon dioxide + water (+ energy)
anaerobic - glucose —> lactic acid (+ energy)
transfers of heat
conduction
heat transfer between two solid objects
particles gain kinetic energy and vibrate
good conductors - copper and other metals
can be stopped by insulators or bad conductors
good insulators - wool
bad conductors - wood
convection
convection current
cold particles replaced by heat particles
can be stopped by air pockets
cold particles are more dense so they fall to the bottom
heat particles are less dense so they rise
radiation
travels in waves
surface area to volume ratio
smaller surface area to volume ratio, cool quicker
larger surface area to volume ratio, cool slower
cells
animal cells
plant cells
