網頁2024年10月21日 · Answer: Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. … 網頁2009年9月27日 · Cell capsule - Bacterial cells have a cell membrane and a cell wall, but they also have a cell capsule. This outermost layer is often made of sugars or special proteins. It helps protect the bacteria from being eaten by larger cells, like animal immune cells, and from being infected by viruses. back to top. 網頁In bacteria, the cell wall is made of a substance called “peptidoglycan.”. The “peptide” part of the substance is from short chains of amino acids called peptides. Amino acids are a major building block of life and are what make up proteins. The “glycan” part is long chains of sugars which along with the peptides make up the mesh of ... cycling shoe cleat wedges
