Document Summary
Chloroplasts originated as cyanobacteria and can divide by binary ssion - similar to mitochondria. Outer envelope membrane large channels = porins proteins allows large molecules to get in and out. Inner envelope membrane does not allow uid to pass through variety of transporters pumps and channels. Thylakoids, grana and stroma lamellae in the stroma. 75: 25 protein: lipid ratio stacks are grand the space in-between the thylakoid sacs is the lumen space outside the thylakoid sac is the stroma stroma lamellae connect the thylakoids from di erent grana. Stroma - similar to mitochondrial matrix: many enzymes contains dna and ribosomes encodes about 100 genes. proteins are unfolded by hsp70 in the cytosol - similar to mitochondria transit peptide interacts with its receptor close to the protein translocation channel on the oem. Toc complex protein is then delivered into the inter membrane space.
