Topic: Intermembrane space of mitochondria

    Note: these results are not from the primary (high quality) database.

lecture11.txt In mitochondria, pH of intermembrane space is 7 (like cytoplasm), pH of matrix is 8 2. In chloroplasts, pH of intermembrane space is also 7, and pH of stroma is also 8; pH of thylakoid space is 5. Therefore 3 compartments instead of 2: intermembrane space, stroma, and thylakoid space. www.unc.edu /courses/pre2000fall/biol052/lectures/lecture11.txt   (1070 words)

Intermembrane space - Wikipedia, the free encyclopedia Because of channels in the outer membrane of the mitochondria, the content of the intermembrane space is similar to that of the content of the cytoplasm. The intermembrane space is the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast. The main function of the intermembrane space is nucleotide phosphorylation. en.wikipedia.org /wiki/Intermembrane_space   (306 words)

BCMB 513 group 3 A family of small proteins in the mitochondrial intermembrane space mediates import of inner membrane proteins across the intermembrane space.. The intermembrane space-targeting sequence (brown) then targets the protein to the inner membrane by binding to a receptor (green) on the matrix side of the inner membrane, after which the protein is translocated across the inner membrane through an associated protein-lined transport channel into the intermembrane space (step 2a). Examples of protiens that utilize this pathway are those whose amino termini face the intermembrane space. www.bio.utk.edu /bcmb513-3   (4486 words)

Chloroplast - Open Encyclopedia Both organelles are surrounded by a double membrane with an intermembrane space; both have their own DNA and are involved in energy metabolism; and both have reticulations, or many foldings, filling their inner spaces. Chloroplasts are similar to mitochondria but are found only in plants. A thylakoid looks like a flattened disk, and inside is an empty area called the thylakoid space or lumen. open-encyclopedia.com /Chloroplast   (304 words)

Re: What can we find between the two membanes of the nucleus enveloppe? The composition of soluble components of the intermembrane space of mitochondria is apparently unknown. The rough ER is part of the protein synthesis machinery: proteins to be exported are synthesized into the lumen (cisternae; intermembrane space) of the ER where they are folded correctly (which may require additional proteins, so-called "chaperones"), sorted and subsequently transported to the golgi apparatus. Some components, however, are facing to the intermembrane space, so that the intermembrane space provides an environment that permits electron transfer, which could be regarded as an indirect function. www.madsci.org /posts/archives/1998-11/911838729.Cb.r.html   (363 words)

Biology 2323: Problem Set 3 These protons will reenter the intermembrane space through the proton channel of the ATP synthase. a) If one could measure the pH within the mitochondria, which region would be more acidic--the intermembrane space or the matrix? It is most likely that the intrathylakoid space will have a higher concentration of protons, and thus be more acidic. department.txwes.edu /bio/cchandra/2323ps7key.htm   (681 words)

LECTURE NOTES ON MITOCHONDRIA AND AEROBIC METABOLISM (RESPIRATION) OF 0.16 VOLTS; THIS MEANS THAT THERE IS A BUILD UP OF POSITIVE IONS IN THE INTERMEMBRANE SPACE/CYTOPLASM BECAUSE H+ IS PUMPED OUT OF THE MATRIX AND THERE IS A SLIGHT NEGATIVE BUILD UP IN THE MATRIX. THE MOVEMENT IS FROM THE INTERMEMBRANE SPACE TO THE MATRIX. IF YOU MAKE THE CYTOPLASM BASIC, THIS WILL MAKE THE INTERMEMBRANE SPACE BASIC ALSO BECAUSE THE OUTER MEMBRANE IS A POOR BARRIER. carbon.cudenver.edu /~bstith/mito.htm   (967 words)
