what is the formula of anaerobic respiration? |
glucose → lactic acid (+ energy released) C6H12O6 → 2C3H6O3 |
|
what is the formula of aerobic respiration? |
glucose + oxygen → carbon dioxide + waterC6H12O6 + 6O2 → 6CO2 + 6H2O
|
|
where does respiration take place? |
in our cells all the time! |
|
what is aerobic respiration? |
when glucose reacts with oxygen inside cells to release energy THIS OCCURS IN EVERY LIVING THING |
|
what type of reaction is respiration? |
it is an exothermic reaction because it gives off energy it doesn't take it in |
|
what is the energy transfer during respiration? |
from chemical energy (glucose) to kinetic, heat and some is used to build larger molecules |
|
how to measure the rate of respiration? |
-volume of oxygen taken in _ volume of co2 produced - temperature change |
|
what is anaerobic respiration? |
during intense exercise our lungs can't deliver oxygen quick enough to our muscle cells for aerobic respiration so anaerobic respiration takes place |
|
why does anaerobic respiration release much less energy? |
because glucose is only partially broken down in anaerobic respiration so not all energy is released |
|
when lactic acid builds up in the muscles what does it cause ? |
pain and fatigue |
|
what does lactic acid do to cells pH? |
lowers the pH of cells so the enzymes in the body can denature so it has to be broken down |
|
what is oxygen debt? |
when we respire anaerobically we have a lack of oxygen getting to muscle cells |
