converts excess glucose to glycogen for storage
converts excess amino acids to urea (deamination)
destroys hormones
removes alcohol from blood
generates heat by respiration, produces bile which emulsifies fat, breaks down toxins (alcohol and drugs as well), produce urea, stores vitamins and minerals ...

Re: Biology,Chemistry & Physics Help Available Here !

am still confused bout diff b/t DNA n Chromosome.......
Chromosomes are thread like structures found in the nucleus and it is made up of DNA and proteins.
DNA is a nucleic acid which contains the genetic information for development and functioning of living organisms.

Q.5(D) can someone please give a rough sketch of how the graph's supposed to be?
if it asked to explain why there is no net movement of CO2 then how?
these are my answer:
1)The carbon dioxide produced during the process of respiration is totally used up the photosynthesis so no extra carbon dioxide is needed.
2)The photosynthesis process is slowing down so the uptake of carbon dioxide is releasing and the net movement of carbon dioxide is zero at that particular time.

Any of these two correct? can i get full mark if this question worth 3marks?! :confused:
