The chloroplast stroma contains ribulose-1, 5-biphosphate carboxylase/ oxygenase (rubisco).Rubisco catalyze the first step of carbon fixation in the Calvin cycle #OrganelleVoteAllen
There are two types of reactions that occur in the chloroplast and they have different locations. The light reaction takes place in the thylakoids and the dark reaction takes place in the stroma of the chloroplast #OrganelleVoteAllen
The chloroplasts thylakoid membrane is extensively folded so it has a bigger surface area to make it easier for diffusion in the chloroplast #OrganelleVoteAllen
When sunlight strikes the thylakoids, the light energy excites chlorophyll pigments, causing them to give up electrons. The electrons then enter the electron transport chain, which is a series of reactions that ultimately drive phosphorylation of ADP #OrganelleVoteAllen
Idk if you knew but chloroplasts use ATP and NADPH during the light-dependent reactions of photosynthesis, which is where carbon and water are assimilated into organic compounds #OrganelleVoteAllen
As a result of the genomes, any proteins by nuclear DNA have become essential to chloroplast function and it uses the transmembrane channels to get the nuclear encoded proteins #OrganelleVoteAllen
Chloroplasts genome is typically round and is roughly 100-120 kilo bases in length before evolution and now the chloroplast genome has been reduced in size #OrganelleVoteAllen
The chloroplast actually has three membranes & they are the outer membrane and the inner membrane which are the membranes that protect the chloroplast & then the thylakoids membrane & it has a space where the stacks of thylakoid stack are also called a granum #OrganelleVoteAllen
Chloroplasts have there own DNA and make there own building blocks. About 10 percent of chloroplasts proteins are encoded by its own DNA #OrganelleVoteAllen
The first photosynthetic eukaryotes originated more than 1000 million years ago through the primary acquisition of a Cyanobacterial endosymbiont #organellevoteallen
Chloroplasts come from a ancient eukaryote engulfing a photosynthesizing bacteria or also know as blue- green algae (can also be Cyanobacterium) #organellevoteallen
In plants, chloroplast occurs in all green tissues even though they are concentrated particularly in the parenchyma cells of the leaf mesophyll #organellevoteallen
The chloroplast is essential to all cells because all life needs plants and the chloroplasts is what keeps them alive by making the sugar that they need to accomplish the other functions they need to accomplish to thrive #OrganelleVoteAllen
Chloroplasts are essential to life and not just plant life because during the reactions that occur through photosynthesis oxygen and glucose and animal life needs oxygen to be able to go through the process of cellular respiration #organellevoteallen
The chloroplast constantly works to make sugars and to do that it goes through a light-dependent photosynthesis which is the series of chemical reactions that light energy is converted to chemical energy #OrganelleVoteAllen
Chloroplasts are important because they help plants stay alive by going through the process of photosynthesis which takes carbon dioxide, sunlight, and water to make energy #Organellevoteallen
