Final answer:
The components of a plasma membrane that provide structural support, transport substances through the membrane, and participate in chemical reactions at the cell surface are lipids, proteins, and carbohydrates.
Step-by-step explanation:
The components of a plasma membrane that provide structural support, transport substances through the membrane, and participate in chemical reactions at the cell surface are:
- Lipids: They include phospholipids and cholesterol and form the bilayer of the membrane.
- Proteins: They can float in the bilayer or be attached to one side or the other. Some proteins serve as transporters for substances.
- Carbohydrates: They are attached to proteins and lipids on the outside surface of the membrane and are involved in cell recognition.
