Cell membrane Ans: Flexible and allows a unicellular organism to move Homeostasis Ans: Balanced internal condition of cells Equilibrium Ans: (Homeostasis) maintained by plasma membrane controlling what enters and leaves cell Functions of plasma membrane Ans: Protective barrier, regulates transport in ad out of cell, allows cell recognition, provides anchoring sites for filaments of cytoskeleton, provides binding site for enzymes, contains cytoplasm Phospholipids 2 Ans: Make up ce...

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...

Phospholipid Bilayer Exam Questions And Answers...

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...

ATI TEAS 6 EXAM STUDY GUIDE 2023|2024 UPDATE Science CeLL Cell: basic organizational unit of all living things. One thing in common is they all have membranes (phospholipids). Cell structure organization: All cells contain DNA, and RNA & can synthesize proteins. Consists of nucleic acids, cytoplasm, and cell membrane. o Tissues: Cells that are grouped together o Organs: Tissues that are grouped together o Systems: Organs that are grouped together o Organism: A complete individual ...
