And serious heart problems may occur if caffeine and monoamine oxidase inhibitors (MAO) are taken together.
-VE
It can result in a false positive result.
Caffeine is a covalent compound.
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
Taking caffeine with the decongestant phenylpropanolamine can raise blood pressure.
No
No. Sinemet is a combination of a prodrug (levodopa, which is converted in the body to dopamine) and an inhibitor that prevents the conversion (the enzyme it inhibits is DOPA decarboxylase; MAOI drugs inhibit monoamine oxidase). The inhibitor is highly polar and cannot pass the blood-brain barrier, so it inhibits the conversion of levodopa to dopamine in the body generally, but allows conversion within the brain. This is done because high levels of dopamine outside the brain can result in nausea and vomiting.
Tobacco and caffeine are very different as addctive substance or drug. There is no way to compare tobacco to caffeine. Besides being very addictive, smoking is very harmful to our health. Caffeine is a single central nervous system stimulant, on a recommended daily amount. Too much caffeine is not advisable.
Caffeine cannot replace sleep and should not be used regularly to stay awake as the drug can lead to more serious sleep disorders, such as insomnia.
Metabolic tests such as an oxidase test can be used to differentiate S epidermidis and E faecalis. Such a test can be conducted by adding H2O2 to the colony. The result for S aureus will be negative and the result for S epidermidis will be positive.
Caffeine is bad for children because according to research certain drinks contain as much as 14 times more caffeine than the average can of cola. This is the same as drinking 7 cups of coffee.
Sure, but remember you will want to document your data and have a control group and non control group. State your hypothesis clearly and what you think will happen as a result of giving the nice caffeine.
