Internal membranes play important roles in protein production and processing except they do NOT

anchor ribosomes in place.
transport substances to different areas.
contain the hereditary information for the protein.
modify proteins to go into vesicles.

No DNA info within the membrane.

so it would be contain the hereditary info for the protein

Hereditary info is contained within the nucleus in the chromosome inside the cell. Not the membrane itself.

but they do anchor ribosomes in place?

yes.they do

In fact ballamoney1, they do not anchor the ribosomes in place. The ribosomes simply float around wherever they please, and when they want to, they flow into the chloroplasts. There they will perform photosynthesis and turn green.

To determine which of the given options about the roles of internal membranes in protein production and processing is incorrect, we need to understand the function of internal membranes and eliminate the option that does not apply.

Internal membranes, mainly found in organelles such as the endoplasmic reticulum and Golgi apparatus, are essential for protein production and processing within a cell. These membranes consist of lipid bilayers and various proteins that perform specific functions.

Let's examine each option:

1. Anchor ribosomes in place: This is a correct statement. Internal membranes provide attachment sites for ribosomes during protein synthesis, ensuring that protein production occurs in specific locations within the cell.

2. Transport substances to different areas: This is also a correct statement. Internal membranes have transport proteins that facilitate the movement of molecules and proteins between different compartments within the cell. This is crucial for directing proteins to their designated locations.

3. Contain the hereditary information for the protein: This statement is incorrect. The hereditary information for proteins is encoded in the DNA of the cell's nucleus and is transcribed into RNA, which is then translated into proteins. Internal membranes are not directly involved in storing or containing hereditary information.

4. Modify proteins to go into vesicles: This is a correct statement. Internal membranes, particularly the Golgi apparatus, play a significant role in modifying proteins. This can include adding sugars or lipids to proteins, ensuring their correct folding, and sorting them into transport vesicles for delivery to specific cellular destinations.

Based on this analysis, the incorrect statement is "contain the hereditary information for the protein." Internal membranes do not store or contain the hereditary information for proteins; that role is performed by the DNA within the cell's nucleus.
