Question

1. in which organelle are proteins made? a) mitochondria b) nucleus c) endoplasmic reticulum d) ribosomes e) golgi body

Explanation:

Ribosomes are the organelles responsible for protein - synthesis. They read the genetic information from mRNA and assemble amino acids into proteins. Other organelles like mitochondria are for energy production, endoplasmic reticulum is involved in protein and lipid synthesis and transport but not the site of initial protein assembly, Golgi bodies modify and package proteins, and the nucleus contains the genetic material but is not the site of protein synthesis itself.

Answer:

d) Ribosomes
