Types of respiration: Anaerobic and aerobic
Definition
a process occur in cells that breakdown complex organic molecules into simple molecules (catabolic rxn) to produce ATP which involves redox rxn
roles of cellular respiration
in the form of ATP and heat energy
energy flows into ecosystem as sunlight and leaves as heat, photosynthesis generates O2 and organic molecules which are used in cellular respiration
to produce energy by living organisms
cells use chemical energy stored in organic molecules to regenerate ATP which powers work
adenosine triphosphate
function
when ATP is hydrolyzed, large amount of energy is released
Adding phosphate is called phosphorylation
act as temporary energy store
enzyme : ATPase
breaking the high- energy bonds between last two phosphate in ATP through hydrolysis process
product
36/38 molecules of ATP formed
structure
ribose sugar
nitrogenous base, adenine
nucleotide with unstable phosphate bond
3 phosphate groups
Needs of energy
respiration
cellular respiration
excitability
transmission of impulse
growth
cell division
excretion
excretion of waste in kidney
reproduction
sperm motility
nutrition
ingestion and digestion
movement
ATP for muscle contraction
types of respiration
aerobic respiration
occur in presence of oxygen
to produce carbon dioxide, water, ATP
complete oxidation of organic compound(glucose)
oxidation of glucose to CO2
reduction of oxygen to H2O
anaerobic respiraton
does not involve oxygen
in plant, anaerobic respiration will produce ethanol,CO2 and ATP
incomplete oxidation of organic compound
in amimal, anaerobic respiration will produce lactic acid and ATP
