LAST BIT OF REVISION!!!

Catalyst: Primary - Acidified Potassium Dichromate Secondary - Acidified Potassium Dichromate 1st product: Primary: aldehyde Secondary: ketone Same agent: Primary: Carboxylic Acid

Bacterial inflection Overuse of aspirin Excess amount of carbonated drinks

H2 Agonists Proton Pump Inhibitors

Rantidine (Zantac)

• Blocks action of Histamine • Reversibly binds to the H2 receptors • Lock and Key Model

it’s the cell lining of the stomach that secrets acid

Proton Pump Inhibtors

Prilosec and Nexium (omraprezole and esomeprazole)

Block enzyme responsible for the pumping of H+ ions out of the cells and into the stomach Permanently deactivate proton pump

Esterification reaction Ethanoic Anhydride + Morphine –> Diamorphine

Nausea, vomitng (any sort of sickness)

Inhibit the enzyme neuraminidase Produced by the virus as part of the mechanism that allows the new viruses to leave the host cell after replication

• Virus attacks the ‘T-cells’ that are essential to the functioning of the immune system, so it prevents the normal immune response involved in recovering from a viral infection • Virus’ can lie dormant inside host cells for many years –> prevents its total eradication

Stigma Difficulties controlling illegal activities such as prostitution

One ethical consideration that a researcher might face while researching medicine is the need to obtain informed consent from study participants.

Atomic radius decreases across period 3. This is because, as we move from left to right across the period, the number of protons in the nucleus increases, which attracts the electrons more strongly, making the atomic radius smaller.

the first ionization energy increases across period 3 Decreases down the group

increasing atomic radius

Positive ions –> smaller Negative Ions –> bigger

Decreases down the group Increases across a period

Sodium –> Basic Aluminium Oxide –> No reaction Silicon dioxide –> No reaction Everything onwards Acidic
