Biology A Unit 3: Lessons 11-14 | with complete solution 2023/24 Lesson 11: - Lesson 11: Phospholipids line up so that their heads point outward, toward water, while their tails point inward. What is this double layer of phospholipids called? - the lipid bilayer What does hydrophobic mean? - lacking an affinity for, or attraction to, water Study the image. What type of membrane protein does label A point to? - glycoprotein Which of these are functions of membrane proteins? Select all that apply. - to send signals across the cell membrane to help move molecules across the membrane to serve as identification for the cell The tail of a phospholipid avoids interacting with water. What term describes this? - hydrophobic What molecules are found in the structure of cell membranes? Select all that apply. - phospholipids proteins carbohydrates Study the image. Which membrane component would help ions to travel in and out of a cell? - XXX WRONG XXX C Which statement best describes the fluid mosaic model? - The fluid mosaic model shows a cell membrane with a pattern-like structure and flexibility. Study the image.
