Major membrane lipids, form a bilayer SI . Molecules that are polar at one end and nonpolar at the other 52. Phospholipid heads are and face water while the tails are and face inwards 53. Tails of phospholipids are composed of 54. Integral proteins are also known as proteins 55. Which molecule is responsible for membrane fluidity 56. Cold stress increases of fatty acid chains of membrane phospholipids. 57. Steroid that adjusts membrane fluidity in animalsand in plants 58. The diverse functions of the membrane are carried by Passive Transport Glides!9-30) 59. Diffusion across a membrane with no energy investment 60. Hydrophilic molecules move across the membrane by 61. O, CO; and other nonpolar molecules move across the cell membrane by 62. Which has a higher osmotic pressure: a) hypertonic b) hypotonic solution 63, A 40% NaCl solution isrelative to a 0.9% cell. - 64. In a hypertonic solution: an animal cell placed will- , while a plant cell will 65. An animal cell placed in a hypotonic solution will while a plant cell will Endocytosis Exocrtasis slides 31-34 66. Bulk transport across membranes occurs by--a_- 67. Phagocytosis involves internalization and hence may be classified as 68. A golgi vesicle secretes cellulose by fusing with plasma membrane to release contents: ctive Transport(slides 35-44 69. Proteins involved in active transport are known as 70. 71. Transport method that makes use of potential gradient built by primary active transport 72. A co-transporter that transports two substances in opposite directions active transport method directly uses ATPExplanation / Answer
50. The answer is Phospholipids.
51. The answer is Amphipathic.
Amphipathic molecules are the molecules which have both hydrophillic and hydrophobic parts present in their structure.
52. The answer is Hydrophilic, hydrophobic.
The hydrophillic portion (head) consistes of a phosphate group whereas the hydrophobic portion (tail) is made up of two fatty acids.
53. The answer is Cholesterol, phytosterol.
