Important for energy storage, Twice as much energy as polysaccharides, made of carbon and hydrogen linked by non polar covalent bonds. 1 of 20 Why are lipids different to carbohydrates? Smaller molecules, not built from monomers. 2 of 20 What are the 3 types of lipids? Fats, Phospholipds, Steroids 3 of 20 What is a fat made up of (Triglyceride) Glycerol attached to 3 fatty acids. 4 of 20 What is a phospholipid made up of? Glycerol and 2 fatty acids. 5 of 20 How do phospholipids deliver drugs into a cell? In aq phospholipids and drug molecules form a lipid bilayer containing the drug. 6 of 20 What is a steroid? lipids in which carbon skeleton contains 4 fused rings. 7 of 20 What is the starting material for making a steroid? Cholesterol 8 of 20 Define nucleic acid? Polymers specialised for storage, transmission and use of genetic information. 9 of 20 What makes up a nucleotide? Phosphate group, Pentose sugar, Nitrogenous base. 10 of 20 What are the bases in DNA? A T G C 11 of 20 What are the bases of RNA? A U G C 12 of 20 As RNA is single stranded where does base pairing take place? Different regions of the molecule. 13 of 20 Base pairing is held together by which bonds? Hydrogen 14 of 20 How does DNA transmit information? Can replicate or can be transcribed and copied into RNA 15 of 20 What is gene translation? RNA specifies a sequence of amino acids in a polypeptide. 16 of 20 Define Genome: Complete set of DNA in an organism. 17 of 20 Define genes: Sequences of DNA that code for a specific protein. 18 of 20 What are 3 other uses of nucleotides? cAMP, GTP, ATP. 19 of 20 What are the 2 theories for origin of life?
