- AVerdadero
- BFalso
3Starch is made of amylose.
- AVerdadero

4The difference between starch and glycogen is that it is even further branched which enables quicker build up and breakdown of glycogen to meet superior energy demands of animals as compared to plants.
- AVerdadero
- BFalso

- ACell mediated
- BHumoral mediated
- CKiller cell
- DHelper cell
6What is the function of a phagocyte?
- AEngulf pathogen
- BDigest pathogen
- CEngulf and digest pathogen
- DSecrete Killer cells
7What is an antigen
- AA protein molecule in the body
- BA protein in the body that stimulates an immune response
- CA protein in the body that has a specific shape to bind to phagocyte cells
8When evaluating data in a question what should you do?
- AAgree, criticise data, propose alternative.
- BAgree with data, propose alternative.
- Cdisagree with data, propose alternative.
9What are the names of disaccharides?
- AMaltose
- BGalactose
- Csucrose
- DFructose
- Elactose
10Names of monosaccharides are...
- ASucrose
- BLactose
- CGlucose
- DFructose
- EMaltose
- FGalactose
11An advantage of a SEM microscope is....
- Athat it is cheap
- Bthat it is user friendly
- Cthat it produces 3D images
12Antibiotics break down the [blank_start]cell wall[blank_end] of a bacterial cell.
- Acell wall
13 Some antibiotics actually kill bacteria, and others just stop them from growing. [blank_start]Bactericidal[blank_end] antibiotics kill bacteria directly, and [blank_start]bacteriostatic[blank_end] antibiotics stop bacteria from growing
- Abacteriostatic
- BBactericidal
14How do B-lymphocytes respond when they are stimulated by antigens?
- ADivide by meiosis
- BDivide by mitosis
- CProduce Tk cells
- DProduce memory cells
- EMake antibodies
15Macrophages stimulate B lymphocytes by presenting the a[blank_start]ntigen[blank_end] on its cell surface membrane (antigen presenting cell (APCs)). They produce c[blank_start]ytokinins[blank_end].
- Antigen
- Bytokinins
16There is usually an interval of several hours between ingesting Salmonella bacteria and suffering diarrhoea and sickness because Salmonella produces toxins, released when bacteria die. It takes time for enough bacteria to die and for bacteria to multiply.
- AVerdadero
- BFalso
17Prokaryotic cells contain ribosomes attached to the endoplasmic reticulum.
- AVerdadero
- BFalso
18DNA in a prokaryotic cell is contained inside a nucleus.
- AVerdadero
- BFalso
19Competitive inhibitors
- AShape different to substrates / prevents access when bonded
- BCompete with substrate for active site
- CCan slow down a metabolic pathway
- DCan speed up a metabolic pathway
- EShape similar to substrates / prevents access when bonded
20Which of the following apply to Optical Light microscopes....?
- A500 000x magnification
- B600 000x magnification
- C400x magnification
- DResolution is 1nm
- EResolution is 2micrometers
- FThere is no vacuum in the microscope
- GSpecimen has to be dead
- HSpecimen can be dead or alive
21Plant cell walls are made of sucrose.
- AVerdadero
- BFalso
22Antibodies:
-Secreted by [blank_start]B-lymphocytes[blank_end] and produced in response to a specific (foreign) non-self antigen
-B-lymphocyte's receptor site matches the non-self-antigen
-Each antibody is produced by one type of B-lymphocyte for only one type of antigen
-An antibody is [blank_start]Y-shaped[blank_end]
B cells divide and form memory cells and antibody-secreting plasma cells:
-[blank_start]Agglutination[blank_end] makes pathogens clump together
-[blank_start]Antitoxins[blank_end] neutralise toxins produced by bacteria
-[blank_start]Lysis[blank_end] digests bacterial membrane, killing the bacterium- AB-lymphocytes
- BT-lymphocytes
- CPlasma cells
- DMacrophages
- EV-shaped
- FX-Shapes

- NCytoxins
- ORER
- PRibosomes
- QCell membrane
- RLysis
23When investigating the mass of a potato when placed in different concentration of sucrose solution, we would expect that that the potato will decrease in mass when the solution is higher in concentration on the outside.
- AVerdadero
- BFalso
24Plasma membrane consists of a phospholipid bilayer studded with proteins, polysaccharides, lipids and starch
- AVerdadero
- BFalso
25Functions of proteins:
-Carrier ([blank_start]change shape for different molecules[blank_end]) for water-soluble molecules such as glucose
-Channels for ions (sodium and chloride ions)
-Pumps use [blank_start]energy[blank_end] to move water-soluble molecules and ions
-Adhesion molecules for holding cells to extracellular matrix
-Receptors enable hormones and nerve transmitters to bind to specific cells
-[blank_start]Recognition[blank_end] sites, which identify a cell as being of a particular type
-[blank_start]Enzymes[blank_end], which speed up chemical reactions at the edge of the membrane
-Adhesion sites, which help some cells to [blank_start]stick together[blank_end]
-E.g. glycoprotein acts as a receptor and recognition site- ADo not change shape for molecules
