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.

Question

Quizplus · Accepted Answer

Proteomic analyses of mitochondria from different cell types have shown that the proteins present in mitochondria can vary between different cell types. This highlights the importance of studying specific organelles in different cellular contexts to fully understand their biological functions. Choices A and D are incorrect, as there are likely still unidentified mitochondrial proteins, and proteomic approaches are commonly used to study mitochondrial proteins. Choice B is also incorrect, as mitochondria contain hundreds of different proteins.
