The smooth ER

Question

Is the site where lipids destined for other cellular components are manufactured
Converts sunlight into chemical energy
Stores water, nutrients, and enzymes
Produces the energy needed to run chemical reactions in the cell

Answer 1

This statement is partially correct. The smooth endoplasmic reticulum (ER) is involved in the synthesis of lipids and detoxification of drugs and toxins. It does not convert sunlight into chemical energy, as that is the role of chloroplasts in plant cells. The storage of water, nutrients, and enzymes is typically done in vacuoles or other organelles in the cell. The production of energy needed for chemical reactions in the cell is primarily the role of mitochondria, not the smooth ER.
