respiration

respiration

glucose + oxygen-- carbon dioxide + water+ energy
energy
1. cannot be created or destroyed
2. measured in joules many forms
3. types of energy
  1. kinetic
    1. found in moving objects
  2. light
    1. radiant energy
  3. heat
    1. thermal energy
    2. heat
  4. chemical
    1. stored in fuel and batteries
why do organisms need to respire
1. metabolism
  1. sum of all chemical process occur in living organisms
2. catabolic process
  1. metabolic reactions that break down large molecules into small molecules
3. anabolic process
  1. metabolic reactions that build larger molecules from smaller molecules
what is respiration
1. it occrs in living cells
2. the process wereby energy stored in complex organic molecules are made to make atp
3. energy currency
  1. all cells are able to make use of the energy released from atp when it is hydrolysed into adp and pi
where atp comes from
1. delivered from rna nucleotide
  1. contains ribose dna deos not contain ribose
biological process
1. movement
  1. mscle contraction microtubule motors
2. activation of chemicls
  1. making molecules more unstable
3. active transport
  1. move molecules across membrane against con grad
what stands for atp
1. adenosine triphosphate
  1. this is an energy bearing molecule found in all living cells
