respiration Flashcards
what is respiration
respiration is a series of chemical reactions in every cell that continuously releases energy from food molecules.
what is the word equation for aerobic respiration
glucose + oxygen —> carbon dioxide + water + energy
what is the balance chemical equation for respiration
C6 H12 O6 —->6co2+ 6h20 + atp
what is the word equation for anaerobic respiration in muscles in the box below.
carbon dioxide —> glucose + oxygen
what is the word equation in anaerobic respiration in yeast
glucose—>carbon dioxide + ethanol + little energy
what happens to the air when it passes throw the nasil cavity
-warmed
-filtered
what does the adaption of the repertory surfaces include.
-large surface area
-thin
-moist
-permeable
-good blood supply
-diffusion gradient
what is breathing rate
the numbers of breaths per minute
what is recovery rate
is the time taken for your breathing rate to return to normal
how leaves adapt for gas exchange
large surface area this is because there are so many spongy messily cells surrounding the air spaces
what is exothermic reaction
a chemical reaction that gives out or releases energy.
what is oxygen
a gas that makes up 21%of air and is needed for combustion and respiration
what is carbon dioxide
a gas that is released by the combustion of fuels and in respiration
what is a lung
made up in the alveoli and is the main organ of gas exchange in the body
what is diffusion
the random movment of molicules or ions from where they are high in concentrations to where they are in a lower concentration
