- RER = ● RER looks rough because it has particles called ribosomes attached to its surface
SER = ● SER looks smooth because it does not have ribosomes attached to its surface
- RER = ● the RER synthesises proteins
SER = ● the SER synthesises fats or lipids
- RER = ● the RER does not help in the detoxification
SER = ● the ser plays a crucial role in detoxifying many poisons and drugs

A substance that can donate a H+ ion is called an acid
Within the context of neutralisation the H+ ion is the substance that accepts an OH- ion to form water, so by extension it kind of implies the substance is an acid
A substance that has a low pH value is also an acid
Therefore the base is the substance that is alkaline

Due to technical problems, you will find the complete answer and explanation in the attached files
The correct answer is: C) ATPase activity must be pumping calcium from the cytosol to the SR against the concentration gradient.
From the example above, we can see that the concentration of calcium is higher in the SR than in cytosol, which means that calcium is moved from the area of lower concentration (cytosol) to the area of higher concentration (SR). This movement is against the concentration gradient and that is the reason for ATPase to act. This process requires energy.
