BIO 101 EXAM QUESTIONS AND CORRECT DETAILED ANSWERS What makes the "head" of a phospholipid hydrophilic? A) The even distribution of electrons across the fatty acids makes the head polar. B) The uneven distribution of electrons across the fatty acids makes the head polar. C) The phosphate group carries a negative charge, making the head polar. D) The phosphate group carries a negative charge, making the head nonpolar - ANSWER C Which would most likely pass unaided through a pla...

Homeostasis Ans: The process of maintaining balance in an organisms internal environment 1. Separates inside of cell from outside of cell 2. Controls the substances that leave and enter the cell Ans: 2 cell membrane functions Their cell membrane allows nutrients to come inside and allows waste to leave Ans: How do cells maintain homeostasis? Phospholipid Ans: A molecule with a glycerol backbone, 2 fatty acid chains, and a phosphate group A glycerol backbone, 2 fatty acid chains, and a p...

Cholesterol Ans: Only found in animal cells. Cholesterol allows the membrane to be more fluid and bends lipids together for selectivity Peripheral Protein: Ans: They're hydrophilic because they are not embedded in the membrane and act as receptor/communication functions of the cell since they are bound to the surface Glycolipids Ans: Carbs attached to lipids Glycoproteins Ans: Carla attached to proteins Intergral Proteins Ans: Connect inside of cell to the outside 2 Carrier Prote...

Phospholipid BilayerPhospholipid - correct answer consists of a somewhat circular phosphate group head, and two long , fatty acid chain tails Hydrophilic Head - correct answer Its attracted to water and arranged to be closest to the water molecules Hydrophobic Tail - correct answer Are repelled by water and arranged to be farthest from water molecules Carbohydrate Chain - correct answer substance on the plasma membrane helps identify chemical signals from outside the cell and define cel...
