Questions: Multiple Choice Question How might lipids synthesized in the mitochondria be transferred to other cellular membranes? • Vesicular transport • Lateral diffusion • Lipid exchange proteins Need help? Review these concept resources.

The answer is the third one: Lipid exchange proteins.

Explanation for each option:

1. Vesicular transport: This process involves the movement of materials within vesicles, which are small membrane-bound sacs. While vesicular transport is a common mechanism for moving proteins and lipids between different parts of the cell, it is not typically how lipids synthesized in the mitochondria are transferred to other cellular membranes. Mitochondria are not directly involved in vesicular transport pathways.

2. Lateral diffusion: This refers to the movement of lipids within the same membrane layer. While lateral diffusion allows lipids to move within a membrane, it does not facilitate the transfer of lipids from the mitochondria to other cellular membranes.

3. Lipid exchange proteins: These proteins facilitate the transfer of lipids between different membranes. They can bind lipids in one membrane and transport them to another, which is a mechanism that can be used to transfer lipids synthesized in the mitochondria to other cellular membranes.

In summary, lipid exchange proteins are the most likely mechanism for transferring lipids synthesized in the mitochondria to other cellular membranes.
