"Eukaryotic cells are more complex than prokaryotic cells. Eukaryotic cells are found in most of the more complex kingdoms of life including fungi, animals, plants and protists. Eukaryotic cells have ...
"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 i ...
"The electron transport system is the stage in cellular respiration in which oxidative phosphorylation occurs and the bulk of the ATP is produced. The electron transport system creates an electron gra ...
"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 ...
"The cytoskeleton provides structure within a cell. It is found in all cells and is important for cellular motion (using structures such as flagella and cilia) and intracellular transport. Cytoplasm i ...
