Which organelle is responsible for the synthesis of proteins in a cell?(1 point) Responses Golgi apparatus Golgi apparatus Nucleus Nucleus Ribosome Ribosome Mitochondrion
Ribosome
The organelle responsible for the synthesis of proteins in a cell is the ribosome. To determine this, let's break down the options and analyze each one:
1. Golgi apparatus: The Golgi apparatus is involved in the modification, sorting, and packaging of proteins that are synthesized in the cell, but it is not directly responsible for protein synthesis.
2. Nucleus: The nucleus is considered the command center of the cell, as it contains the genetic material (DNA) that codes for proteins. However, protein synthesis itself does not occur in the nucleus.
3. Ribosome: Ribosomes are the correct answer. They are tiny organelles found either floating free in the cytoplasm or attached to the rough endoplasmic reticulum. Ribosomes are responsible for the actual synthesis of proteins. They read the instructions encoded in the messenger RNA (mRNA) molecule and use them to build proteins by linking amino acids together.
4. Mitochondrion: Mitochondria are the "powerhouses" of the cell, responsible for generating energy. Although they are involved in certain protein synthesis processes, their primary role is not the synthesis of proteins.
Therefore, the correct answer is the ribosome.
