WebMar 26, 2024 · During the process of photorespiration carbon dioxide is released and also energy is utilized. So we can say photorespiration wastes energy and decreases the synthesis of sugar as it releases carbon dioxide utilized for the sugar production. It is also known as the C$_2$cycle. It is initiated in chloroplast but it occurs in peroxisomes. WebJan 13, 2024 · The analysis revealed that increasing CO 2 during the last 100 years has reduced photorespiration, which has probably boosted carbon storage in peatlands to date and dampened climate change. WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3.
