Organelle associated with photorespiration is (a) Ribosome (b) Peroxisome (c) Nucleosome (d) Mesosome
Answers
" Organelle associated with photorespiration is (b) Peroxisome.
Peroxisomes are membrane bound organelles which produce around fifty different enzymes which are involved in various metabolic reactions in the cell.
In leaves, the peroxisomes play a major role in photorespiration.
Sometimes, during the first step, RUBISCO enzyme adds one molecule of oxygen instead of carbon-dioxide and thus forms one molecule each of 3-phosphoglycerate and phosphoglycolate.
Phosphoglycolate is converted into glycolate and then is sent to peroxisomes where it is converted to glycine.
Two molecules of glycine combine to produce serine in the mitochondria and this serine is taken up by the peroxisomes and is converted into glycerates which reenters into the Calvin Cycle.
