BIOL1020 UQ Module 1 EXAM QUESTIONS (189
TERMS) WITH VERIFIED DEFINITIONS UPDATED
2024

1). What do cells have in common?

 Ans: Have a cell membrane made of a lipid-bilayer (hydrophobic head & hydrophobic
tail)


2). Is the lipid bilayer semi-permeable?

 Ans: Yes


3). What is the most common form of energy?

 Ans: ATP (adenosine triphosphate)


4). What are the different types of cells?

 Ans: Prokaryotic and Eukaryotic


5). What are the basic building blocks of cells?

 Ans: Macromolecules: big molecules (polymers) comprised of interconnecting
individual units (monomers)


6). What are carbohydrates?

 Ans: Macromolecules that provide fuel and structure to cells


7). Define a dehydration reaction from polymerisation

 Ans: Monomers form large polymers, the byproduct being water

, 8). Define polymer synthesis: hydrolysis

 Ans: the chemical breakdown of a compound due to reaction with water.


9). A single unit of a sugar molecule is known as?

 Ans: Monosaccharides (e.g Glucose)


10). Define disaccharides?

 Ans: ~ A molecule that is made up of two monosaccharides (sugar molecules)


11). Many units of sugar molecules linked together is known as

 Ans: Polysaccharides


12). List one example of a disaccharides?

 Ans: Maltose, sucrose, lactose


13). A bond between two sugar molecules are known as?

 Ans: Glycosidic bond


14). Define stereoisomers

 Ans: Compounds with the same structural formula but with a different arrangement of
the atoms in space.


15). What is the difference between galactose and glucose

 Ans: OH bond location at the 4th carbon (glucose is bottom, galactose is top)


16). Define when α-glyosidic bonds are formed

 Ans: When both carbons have the same stereochemistry

, 17). Define when a β-glycosidic bond occurs

 Ans: When two carbons have different stereochemistry


18). Starch is a major storage form of glucose in plants, what bonds can be formed

 Ans: 1-4 and a few 1-6 linkages (branching)


19). Glycogen is mainly located in the liver, kidneys and muscle, does this mean that it is a
major storage form of glucose in animals?

 Ans: Yes


20). What bonds does glycogen have?

 Ans: 1-4, and frequent 1-6 linkages (branching)


21). Explain why cellulose is so tough

 Ans: Cellulose is in a beta configuration that is indigestible by many animals due to
the lack of enzymes, this beta configuration and the lack of branching in the polymer
allows for a structural plants structural integrity


22). What does gi index stand for and what does it measure?

 Ans: Glycaemic Index and measures how quickly your blood-glucose level rises after
eating carbohydrate-containing food


23). What are glycoproteins?

 Ans: proteins covalently bonded to carbohydrates


24). What is chitin?

 Ans: a fibrous substance consisting of polysaccharides and forming the major
constituent in the exoskeleton of arthropods and the cell walls of fungi.


25). Lipids are grouped together to

 Ans: function as a storage compound as they poorly mix with water
