E) mitochondria

Question

Quizplus · Accepted Answer

The smooth ER is responsible for lipid synthesis, including the production of the phospholipids that make up the cell membrane. The rough ER is involved in protein synthesis and processing. The Golgi body modifies and packages proteins and lipids, but does not synthesize them. Peroxisomes are involved in metabolizing fatty acids and other compounds, but do not synthesize lipids. Mitochondria are responsible for ATP production through cellular respiration, but are not involved in lipid synthesis.
