stroma biology definition

CallUrl('learn>genetics>utah>edubiomedcentral>com1186comshtml',0), Also known as the Calvin cycle, these three reactions - carbon fixation, reduction and regeneration of ribulose bisphosphate (RuPB) - form the second stage of photosynthesis, in which glucose is produced. Stroma DefinitionStroma commonly refers to the fluid filled inner space of chloroplasts surrounding thylakoids and grana. Grana are a necessary part of the process of photosynthesis. These membranes form the chloroplast envelope. 2. Stroma Definition. CallUrl('vcebiol>wordpress>combiology>arizona>eduhtml',0), For instance, in animals, an organ would usually consist of the main tissue together with the parenchymal (functional) and the ~TildeLink()l (structural) tissues. CallUrl('www>ukessays>comphp',1), Enclosed by the chloroplast membrane is the ~TildeLink(), a semi-fluid material that contains dissolved enzymes and comprises most of the chloroplast's volume. ta (-mə-tə) 1.
