Question


Tell me which answer choice works best, thank you and for #12 letter choice d is on page 3 d. size. 11. Proteomic studies allow for the identification of all proteins within an organelle, assuming the organelle can be purified sufficiently well. Proteomic analyses of mitochondria from different cell types revealed what interesting finding? a. Mitochondrial proteins have all been identified over the years. b. Mitochondria contain less than 40 different proteins. c. Mitochondria in different cell types can contain different proteins. d. Mitochondrial proteins cannot be examined using proteomic approaches 12. Fluorescence microscopy of cells that are labeled with a green fluorescent antibody against microtubules (a cytoskeletal component) differs from cells expressing green fluorescent protein (GFP) tagged to beta tubulin (a component of microtubules) in all the following ways EXCEPT a. the antibody labeled cells need to be permeabilized before visualization, while the GFP cells do not. b. the microtubules could change their localization over time in the GFP cells, but not in the antibody labeled cells c. the GFP cells do not need to be treated with fixatives, but the antibody labeled cells do next page . (see d on Page 2 of 3

Explanation / Answer

1. The answer is c.

Explaination:

The mitochondrial proteome yeast contains about 750 mitochondrial proteins whereas human heart contains about 650 mitochondrial proteins. In plant mitochondrial proteins, about 400 mitochondrial proteins are identified and 20% are still unknown.
