Question Completion Status: QUESTION 1 You observe a prokaryotic cell under the microscope and you see numerous hairlike extensions the cell uses to adhere to surfaces. These are called pli (plural of pilus) o flagella O cilia fimbriae QUESTION 2 Movement of the chromosomes and maintainance of cel shape is regulated by the O cilia o cytoskeleton cell wall endo membrane system QUESTION 3 lower the activation energy of a reaction inhibit metabolic reactions are modified into products during the course of a reaction increase the activation energy of a

Solution

Fimbriae help in adhering to surfaces. Cytoskeleton – movement of chromosomes and maintenance of cell shape. Enzymes lower the activation energy of a reaction. Ribosomes can be found in rough ER and cytoplasm Lose water Active transport DNA in prokaryotes is found in nucleoid Plasma membrane- a mosaic of proteins suspended within a phospholipid bilayer A and B, with A the activation energy without an enzyme and B with an enzyme. Phospholipids are produced in smooth endoplasmic reticulum and modified in golgi Facilitated diffusion requires the help of carrier protein and movement is down the concentration gradient. Inhibitors bind to or change the shape of enzyme’s active site. Lysosomes- garbage and recycling center Mitochondria are found in all eukaryotic cells Blood (0.9% solutes) is hypotonic compared to sea watter (3.5% solutes) as blood has a lower concentration of solutes.
