The Endoplasmic Reticulum (ER)is a Single Membrane Continuous with the Nuclear

question 69

Multiple Choice

The endoplasmic reticulum (ER) is a single membrane continuous with the nuclear envelope and a series of interconnected sacs throughout the cell.Why might it be beneficial to the cell for the ER to be continuous with the nuclear envelope?

• A)It might be beneficial because it takes less energy,DNA,carbohydrates,and phosophlipids for the ER to synthesize centrioles.
• B)It might be beneficial for the ER and nuclear envelope to be connected because it might make it easier for messages to get from the nucleus to the ER where proteins and lipids are made for the cell;this would most likely require the use of less energy.
• C)It might be beneficial for the ER and nuclear envelope to be connected because it would make it easier for the nucleus to actually carry out cellular respiration.
• D)It might be beneficial for the ER and nuclear envelope to be connected because it would make it easier for the ER to carry out photosynthesis.
