i. Function: Ribosomes make protein synthesis. They are involved in the first step of breakdown of sugar. They carry out genetic instructions. These genetic instructions are translated into proteins.
ii. Analogy: Ribosomes are like small pieces such as charms of the bracelet. Those charms create a bracelet the same way as ribosomes create proteins.
c. Rough ER
i. Function: Part of endoplasmic reticulum. Secretory proteins are kept separate from proteins which can be found in the cytosol by ER membrane.
d. Smooth ER
i. Function: Part of endoplasmic reticulum. Smooth ER synthesises lipids such as proteins, oils, phospholipids, and steroids. Plays an important role in detoxification of drugs and poisons.
i. Function: Break ingested substances, and recycle damaged organelles.
