CELL PHYSIOLOGY PRACTICE QUESTIONS AND ANSWERS GRADED A+ How big is a typical human cell and can you see it with the naked eye? - Correct Answer ️️ -10 um and no Why is a cell roughly 10 um? - Correct Answer ️️ -This size allows the cell to effectively communicate with its environment through its plasma membrane. What would happen if a cell got bigger than 10um? - Correct Answer ️️ -cell's membrane would not be able to efficiently communicate with its environment due to the ...

Gap Junctions - What are the Attachments between cells that permit intercellular communication Connexins - What are the Channel proteins that permit communication in gap junctions Tight junctions (zonula occludens) - What Prevents paracellular movement of solutes between cells Increased oil/water coefficient of the solute (more lipophilic) Decreased size of the solute Decreased membrane thickness - What are the three factors that increase permeability of a solute in a membran

Define the basic structural and functional unit of life - Cell All living organism are composed of - Cells How many cells are in the human body? - 50 to 100 trillion What are the three main regions of the cell? - Plasma Membrane, Cytoplasm, Nucleus What is the thin and flexible membrane of the cell which separates the intracellular from extracellular fluid? - Plasma Membrane What is another name for the Plasma Membrane - plasmalemma

Cell Theory - Every living thing is made up of cells Basic Tenent of biology Prokaryotes - Cells with no nucleus lack internal cellular bodies called organelles do not divide by mitosis included= bacteria Eukaryotes - Have nucleus Have organelles divide by mitosis included= plants, animals, humans

How big is a typical human cell and can you see it with the naked eye? Correct Answer: 10 um and no Why is a cell roughly 10 um? Correct Answer: This size allows the cell to effectively communicate with its environment through its plasma membrane. What would happen if a cell got bigger than 10um? Correct Answer: cell's membrane would not be able to efficiently communicate with its environment due to the increase in size. What are the 2 major classes of cells? Correct Answer: Solar ce...
