Where are proteins carbohydrates and lipids found in animal cells? Also what is their function?
Lipids are found in cell membranes, two-lipid layers for a bi-layer in all cell membranes. This lipid bi-layer is important because it allows the contents of the cell to be separated for the extracellular fluid. Lipids are also used to make other compounds such a cholesterol. Carbohydrates, are used for energy. Example, glucose is used in respiration and energy is released. Glycogen is used to store energy and when we need this energy is it broken down into glucose. Cellulose is another important carbohydrate used in plant cell wall. Glucose would be dispersed throughout the cytoplasm and glycogen would be found in granules. Proteins have A lot of functions, but one of their most important is that they are enzymes. As enzymes they catalase all the metabolic reactions in living systems. Some proteins example collagen is an important component in muscle. Keratin is found in hair, nails, horns and feathers. Proteins are found everywhere in the cell, it really depend on their function.
