Catalytic Activity of Enzymes in Living Tissues. Objective: To study the role of enzymes (specifically catalase) in living cells and understand how temperature and tissue integrity affect them. Materials: 3% hydrogen peroxide ( H2O2cap H sub 2 cap O sub 2 ), test tubes, raw/boiled potato, raw/boiled meat, sand. Procedure:
Prepare a temporary mount of onion epidermis (stained with iodine). Observe and sketch the cell wall, cytoplasm, and nucleus.
Since the curriculum for Grade 10 Biology in Russia varies slightly by textbook (e.g., Pasechnik, Belyaev, or Teremov), usually focuses on one of three foundational topics in cytology or biochemistry.
