Carbohydrates and lipids are composed of the same chemical element, but in different proportions. Both are used primarily as energy source for metabolic process. Which type of biomolecule has the higher calorie content per gram? Explain briefly.

You have a cellulose sack that is impermeable (i.e. NOT permeable) to starch molecules and is filled with a solution, comprised of 20% starch.  It is placed in a container of 100% distilled water.     a) What term describes the solution in the sack compared to the solution surrounding it?    i) HYPERTONIC ii) HYPOTONIC iii) ISOTONIC   b)  In which direction will the water molecules move faster?   i) INTO THE CELL ii) OUT OF THE CELL iii) SAME IN BOTH iv) NOT AT ALL   c) In which direction will the starch molecules move? i) INTO THE CELL ii) OUT OF THE CELL iii) SAME IN BOTH iv) NOT AT ALL

Which of the following membrane lipids have a direct glycosidic linkage between the head-group sugar and the backbone glycerol? a) Ether lipids b) Sphingolipids c) Glycolipids d) Phospholipids

Which of the following is not a type of lipid? A) lipoproteins B) glycerides C) enzymes D) steroids E) unsaturated fatty acids

Identify (1) the group where the lipid belongs, and (2) determine whether the lipid is saponifiable or non- saponifiable.

Predict the order of the melting points of triglycerides containing fatty acids, as follows: From lowest to highest melting point Drag and drop your selection from the following list to complete the answer: linolenic, lauric, palmitic palmitic, palmitic, stearic palmitoleic, linoleic, oleic

Which of the following lipids would have the highest melting point temperature? 16:0 16:3 18:0 18:1 18:2

Identify the structure and function of starch.  Which monosaccharide(s) is (are) the building block of starch?  Where in narure can starch be found?

"All the glycoproteins and glycolipids in intracellular membranes have oligosaccharide chains facing the luminal side, and all those in the plasma membrane have oligosaccharide chains facing the outside of the cell" is true or false.
