Ribosomes, Endoplasmic Reticulum, Golgi Apparatus, Mitochondrion.
Ribosomes are responsible for synthesizing proteins and forming amino acids. This process is also known as translation and occurs after DNA replication and transcription. Ribosomes read as they move along the messenger RNA template that is used to copy a particular DNA sequence and produce an amino acid chain
The endoplasmic reticulum is an organelle in which an array of cell functions takes place, notably including the production of proteins, steroids and lipids. Proteins are formed in ribosomes, found in the rough endoplasmic reticulum. Steroids and lipids are formed in the smooth endoplasmic reticulum.
Definition and functions of the endoplasmic reticulum.
The Golgi apparatus, also known as Golgi body or Golgi complex, is an organelle commonly found in eukaryotic cells. The Golgi apparatus is made up of membrane-bound stacks and is responsible for production of lysosomes, which aid in digestion.
The description of Golgi Apparatus.
Mitochandria - Mitochondrion
Mitochondria, also called mitochondrion, are organelles found in eukaryotic cells in which aerobic cellular respiration takes place. Mitochondria generate ATP which cells use for energy and have both an outer and inner membrane. The space between two mitochondria is called the christa, while the space inside the inner membrane is called the matrix.
