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...

HESI Retake Anatomy and Physiology Graded A 1. What is the most abundant tissue type in the body? ️Connective tissue 2.

What is the functional unit of the kidney? ️The nephron. 5. What must happen for inhalation to occur? ️The diaphragm contracts, enlarging the chest cavity and drawing in air. 6. What are neutrophils?...

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 Bilayer Phospholipid - 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 c...

AQA A LEVEL BIOLOGY Paper 1 2024 What is the function of the cell membrane? - Correct Answer To control what enters and leaves the cell, acts as a barrier between the cell and its environment. What structural feature of the cell membrane allows substances to enter/leave? - Correct Answer Partially permeable What is the fluid mosaic model? - Correct Answer States that a membrane is a fluid structure (because phospholipids are constantly moving) with a "mosaic" of various proteins embedde...
