In the human body, food we have digested reacts with oxygen in the mitochondria to make energy for the cell. The cytoplasm includes not just the fluid but also all of the stuff in the fluid while the cytosol is referring to the fluid alone and then depending on the complexity of a cell, so this is right here, this is a yeast cell, this is a eukaryotic cell which we cover in more depth in other videos but one of the features of a eukaryotic cell is.
