AQA A LEVEL BIOLOGY EXAM PREP TEST
BANK VERIFIED QUESTIONS AND
CORRECT ANSWERS
●● Sucrose
Answer: Which disaccharide is not a reducing sugar?
●● Test for non-reducing sugars
Answer: Add acid. Neutralise. Add Benedicts. Heat.
●● Hydrolysis
Answer: Reaction performed by dilute HCl in the non reducing sugar
test.
●● Glucose + fructose
Answer: During the non-reducing sugar test what is sucrose hydrolysed
into?
●● Alpha
Answer: Which type of glucose makes up starch?
●● amylose and amylopectin
,Answer: Names of two types of starch
●● Amylose
Answer: Coiled, compact form of starch. Stored easily.
●● Amylopectin
Answer: Branched form of starch. More easily hydrolysed.
●● surface area
Answer: Branched carbohydrates have a higher _____ for enzymes to
work on.
●● Glycogen
Answer: Carbohydrate store in animals
●● branched
Answer: Glycogen is....
●● metabolic rate
Answer: Glycogen is more branched than amylopectin because animals
have a higher _____________
●● osmotically inactive.
,Answer: Starch is insoluble and therefore ....
●● Beta
Answer: What type of glucose is cellulose made from?
●● Alpha and beta glucose
Answer: H and OH swapped on Carbon 1.
●● Fibrils
Answer: Cellulose forms long chains called...
●● H bonds
Answer: Cellulose molecules are crosslinked by
●● strength
Answer: Cross linking of cellulose molecules gives them...
●● Triglycerides
Answer: _______ are a good source of energy because they have a high
ratio of energy-storing carbon-hydrogen bonds
●● what are the roles of lipids?
, Answer: 1. source of energy
2. waterproofing
3. insulation
4. protection
●● how does the structure of phospholipids relate to their properties?
Answer: 1. polar, therefore will position itself to form a bilayer
2. the structure allows them to form glycolipids by combining with
carbohydrates within the cell-surface membrane. these are important in
cell recognition.
●● draw the structure of an amino acid
Answer:
●● draw how a dipeptide forms
Answer:
●● what is meant by 'primary sequence' of a protein
Answer: The unique sequence of amino acids that make up a protein or
polypeptide chain
●● what is meant by 'secondary sequence' of a protein
