1Proof reading of DNA occurs in the [blank_start]G2[blank_end] phase of the cell cycle
- AG2
- BS
- CM
2During anaphase in mitosis the chromatids are pulled apart by the spindle fibres.
- AVerdadero
- BFalso
3During prophase in mitosis the chromosomes line up down the middle of the cell.
- AVerdadero
- BFalso
4Binary fission occurs in [blank_start]prokaryotes[blank_end].
- Aprokaryotes
- Beukaryotes
5During the formation of tissue fluid, the blood at the ateriolar end of the capillary has a [blank_start]higher[blank_end] hydrostatic pressure and water potental than the surrounding tissue fluid.
- Ahigher
- Blower
- Csimilar
6Excess tissue fluid is drained into the:
- ADigestive system
- BLymphatic system
- CReproductive system
- DRespiratory system
7Meiosis results in [blank_start]4[blank_end] [blank_start]haploid[blank_end] daughter cells.
- A2
- B4
- C1
- Dhaploid
- Ediploid
8Glucose is transported by [blank_start]co-transport[blank_end] in the illeum where it moves with [blank_start]sodium[blank_end] ions from the lumen of the illeum into the intestinal cells.
- Aco-transport
- Bdiffusion
- Cactive transport
- Dosmosis
- Esodium
- Fcalcium
- Gmagnesium
9After triglycerides have been broken down into monoglycerides, [blank_start]glycerol[blank_end] and fatty acids, bile binds with the monoglycerides to form [blank_start]micelles[blank_end].
- Aglycerol
- Bmicelles
10[blank_start]Endo[blank_end]peptidases break up within a protein. [blank_start]Exo[blank_end]peptidases break bonds at the end of protein molecules.
- AEndo
- BExo
11Amino acids are absorbed by [blank_start]co-transport[blank_end].
- Aco-transport
12After the [blank_start]photolysis[blank_end] of water, electrons are transported in an electron transport chain in the [blank_start]thylakoid[blank_end] membrane. the energy from this goes into pumping protons across the membrane. The protons move back across the membarne via an [blank_start]ATP[blank_end] synthase channel. ATP is produced as NADP is reduced.
- Aphotolysis
- Bthylakoid
- CATP
13The reaction between carbon dioxide and RuBP in the Calvin cycle is catalysed by the enzyme [blank_start]rubisco[blank_end].
- Arubisco
14The order of stages in respiration is:
>[blank_start]Glycolysis[blank_end]
>[blank_start]The link reaction[blank_end]
>[blank_start]The Krebs cycle[blank_end]
>[blank_start]Oxidative phosphorylation[blank_end]- AGlycolysis
- BThe link reaction
- CThe Krebs cycle
- DOxidative phosphorylation
15In oxidative phosphorylation, oxygen acts as the [blank_start]final electron acceptor[blank_end].
- Afinal electron acceptor
16Anaerobic respiration in animals produces [blank_start]lactic acid[blank_end], and in yeast produces [blank_start]ethanol[blank_end].
- Alactic acid
- Bethanol
- Cwater
- DGlucose
17[blank_start]Calcium[blank_end] ions bind to troponin to move the [blank_start]tropomyosin[blank_end] out of the way to start the process of a muscle contration.
- ACalcium
- BSodium
- CHydrogen
- Dtropomyosin
- Eactin
- Fsarcoplasm
18Blood glucose levels that are too high are detected by [blank_start]beta[blank_end] cells, that produce [blank_start]insulin[blank_end] which causes glucose to be converted to [blank_start]glycogen[blank_end].
- Abeta
- Balpha
- Cinsulin
- Dglucagon
- Eglycogen
- Fstarch
- Gamino acids
19The process of converting glycogen to glucose in the liver is called
- AGluconeogeesis
- BGlycogenolysis
- CGlucolysis
20In the Bowman's capsule, the [blank_start]afferent[blank_end] arteriole has a greter diameter than the [blank_start]efferent[blank_end] arterole which means the pressure is [blank_start]higher[blank_end] in the glomerulus than the bowman's capsule.
- Aafferent
- Befferent
- Chigher
- Dlower
- Ethe same
21ADH is released by the hypothalamus
- AVerdadero
- BFalso
22Increasing the number of aquaporins in the cells of the collecting duct causes the collecting duct to become more permeable to water.
- AVerdadero
- BFalso
23During the polymerase chain reaction, the sample is heated to [blank_start]95°C[blank_end] to separate the strands. It is then cooled to [blank_start]55°C[blank_end] to allow the primers to attach. It is finally heated to [blank_start]72°C[blank_end] so DNA [blank_start]replication[blank_end] can occur.
- A95°C
- B55°C
- C72°C
- Dreplication
- Edivision
- Fhybridisation
24[blank_start]Variable number tandem repeats[blank_end] are short sequences of DNA that vary in length from person to person and are used in genetic fingerprinting.
- AVariable number tandem repeats
25In gel electrophoresis, the larger fragments of DNA travel [blank_start]less[blank_end] than the smaller ones.
