WebPhotorespiration is a process which involves loss of fixed carbon as CO 2 in plants in the presence of light. It is initiated in chloroplasts. This process does not produce ATP or NADPH and is a wasteful process. Photorespiration occurs usually when there is the high concentration of oxygen. WebDuring Photorespiration, no sugar or ATP molecules are synthesized but carbon dioxide is released at the expense of ATP, making the whole process wasteful. As a result, C3 plants undergoing photorespiration often do not yield a decent yield. popular perfumes early 2000s

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. 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.
