BIOL 110 Principles of Biology
1.Describe the structure of a plasma membrane.
2.Define an amphipathic molecule and give an example.
3.Explain the difference between integral and peripheral proteins.
4.Describe the fluid-mosaic model of a membrane.
5.Identify and discuss the function of proteins located in the plasma membrane.
6.Explain the difference between glycoproteins and glycolipids.
7.Why can carbon form chemical bonds with so many elements?
8.Explain the meaning of concentration gradient as it pertains to movement of substances into and out of cells.
9.Explain diffusion and osmosis.
10.What molecule is thought to facilitate the movement of water molecules through a plasma membrane?
11.Explain the difference between active and passive transport across the plasma membrane. Provide examples that occur in the human body.
12.Explain the impact to a cell if placed in a hypertonic solution; include a definition of hypertonic solution and why the change occurs.
13.Identify a similarity and difference between facilitated transport and active transport. Do not state that both move substances across the membrane.
14.Explain the sodium-potassium pump and identify the type of membrane protein involved.
15.Identify and explain the process used by cells to secrete substances.
16.Explain the composition of a plant cell wall and how it differs from the cell wall of a prokaryotic cell.
17.Explain the plasmodesmata and identify the kingdom in which they are found.
18.Define energy and identify the two basic forms of energy.
19.Define entropy.
20.Define metabolism.
21.Explain the difference between exergonic and endergonic reactions.
22.What are coupled reactions and what roles can ATP serve in these reactions?
23.Explain the difference between oxidation and reduction reactions.
24.What is energy of activation?
25.What factors affect the speed of enzymatic reactions?
26.What is an electron transport chain?
27.What occurs at the active site of an enzyme?
28.Define enzymatic inhibition.
29.Define chemiosmosis.
30.Define vitamins and identify their function.
