The Cell The cell is one of the most important concepts in biology since every living organism is made of cells. Bacteria are single celled while you are made up of trillions of cells. As different as we are from bacteria, our cells share some important similarities. All cells have a cell membrane that separates them from the outside environment and all cells have ribosomes where proteins are made.

One main distinction is that plants have a cell wall outside the cell membrane that animal cells lack.

Campbell's Biology, 9e (Reece et al.) Chapter 11 Cell Communication Students will encounter the topic of cell signaling repeatedly in this course and throughout their studies of biology. Therefore, the more confident they are regarding the basic principles, the more successful they are liable to be when encountering the topic. This chapter includes more higher-skill-level questions and makes connections to the principle of evolution as well as to other chapters of the text. Multiple-Choice Questions 1) Using the yeast signal transduction pathways, both types of mating cells release the mating factors. These factors bind to specific receptors on the correct cells, A) which induce changes in the cells that lead to cell fusion.

Campbell's Biology, 9e (Reece et al.) Chapter 7 Membrane Structure and Function Membranes and membrane transport are fundamental to cellular life. The concepts in this chapter require integration of concepts from previous chapters: the nature of water and hydrophobic versus hydrophilic molecules, the properties of lipid molecules and their role in regulating membrane fluidity, and the roles of proteins and carbohydrates in membrane function. The concepts of ion transport and electrochemical gradients across membranes are important foundations for the following chapters on energy metabolism. Finally, the bulk transport phenomena have important clinical significance in the immune system, during invasion by pathogens, and in cell signaling. Multiple-Choice Questions

Cell Biology Objectives and Worksheet 2: Cell-to-Cell and Signal Transduction Name____________________ Objectives: Write out material in your course notebook. Cell to cell communication and signal transduction. Distinguish among types of cell-to-cell communication {autocrine, paracrine, endocrine, cytokine, cell surface markers, neurotransmitter} List major classes of receptors. Explain or diagram the specific structural components of the types. List and describe the components of signal transduction and the molecules involved. Write out specific second messenger signal transduction pathways (see tables 6.1 & 6.2). Define each of the following and predict their effect on signal transduction: agonist and antagonist for one receptor

Properties of water

Water Potential (?) Water potential (?) is a measure of water?s potential to do work. In order to do work, an object must be able to apply enough force to another object to cause displacement. In order for water to displace another object, water must be moving. The largest water potential any volume of water can have, if only standard atmospheric pressure is being applied to that volume of water, is defined as 0. This is the water potential for distilled water. Distilled water has the greatest potential to move, and thus displace another object.

Practice Problems ? Osmosis and Water potential Use this key to answer all the problems below. If you choose B or C, rewrite the statement so that it is complete and true. A = TRUE B = FALSE C = NOT ENOUGH INFORMATION PROBLEM ONE: The initial molar concentration of the cytoplasm inside a cell is 2M and the cell is placed in a solution with a concentration of 2.5M. Initially, free energy is greater inside the cell than outside It is possible that this cell is already in equilibrium with its surroundings. Initially, solute concentration is greater outside the cell than inside. Water will enter the cell because solute potential is lower inside the cell than outside.
