C1.2 #2 Flashcards
(11 cards)
order of respiratory substrates we use
glucose
lipidd and fatty acids
diffrent sugard and carbohydrates
proteins (last resport)
aerobic and anaerobic repsiraton comparrison
oxygen:
aerobic needs
anaerobic doesnt
<location
aerobic cytoplams and mitochonria
anaerobic only cytoplams cause only does glycolysis
respiratory substratex
aerobic- all
anaerobic only carbohydrates
ato yeild
aeobic-high
anaerobic-low
waste products-
aerboic co2 and water
anaerobic lactate/lactic acid
aerobic respiration equation in humans
c6h12o6+6o2=6co2+6h2o + atp
aerobic respiration equation in humans
c6h12o6= C6H12O6 (lactate ) and atp
respiration rate is impacted by
ºc
ph
substrate concenttation(glucose)
o2 concentration
we can measure respiration using a
respirometer
how does a respirometer measure the amount of respiration (write down)
n Tube A, the organisms to be tested (such as insects or germinating seeds) are positioned, and the tap is closed. The organism starts respiring, consuming O2 and producing CO2 and H2O. The alkaline solution at the bottom of Tube A will absorb the CO2 which will decrease the volume of gas by an amount equivalent to the volume of oxygen absorbed. Tube B is the control where no O2 is used or CO2 produced because no living organism is present. The capillary connecting the two tubes is a manometer.
The reduction in oxygen in Tube A will reduce the pressure in Tube A and will move the coloured liquid in the manometer in the direction of Tube A. This provides an indirect measurement of the oxygen consumed, allowing the rate (amount of oxygen consumed per time unit) to be calculated.
rate=
amount/time
NAD
coenzyme
can be reduced or oxidised
H carrier- so is an oxidiser, while becoming reduced
becomes NADH
generates majority of atp in oxidative phosphoyrlation
aim of glycolysis
splits single molecule of glucoes (6c) into 2 pyruvate (3c)
