1.3: Membrane Structure and transport Revision questions test review with correct answers a+ rated 2025. Draw a simplified diagram of the structure of the phospholipid, including a phosphate-glycerol head and two fatty acid tails. Understanding: Phospholipids form bilayers in water due to the amphipathic properties of phospholipid molecules. Head = phosphate and glycerol Tails = fatty acids

A Level Biology- Cell membrane structure, Topic Revision questions test review with correct answers a+ rated What are phospholipids? A phospholipid molecule is a lipid with two distinct sections: -a polar hydrophilic head region consisting of glycerol and a phosphate group. -a non-polar hydrophobic end consisting of two fatty acid tails. How does a phospholipid differ from a lipid molecule? In a phospholipid, there are only two fatty acids and a negatively charged phosphate group repla...
