15 Questions
What defines a molecule as a free radical?
Possessing one or more unpaired electrons in its outer shell
How are free radicals formed?
Via the breakage of a chemical bond such that each fragment keeps one electron
In what way can redox reactions contribute to the formation of free radicals?
By transferring electrons between molecules, leading to the generation of free radicals
Free radicals are always formed from molecules via the cleavage of a radical to give another radical.
True
Redox reactions do not contribute to the formation of free radicals.
False
A molecule with one or more unpaired electrons in its outer shell is not considered a free radical.
False
True or false: Free radicals are only formed from molecules via the breakage of a chemical bond?
False
True or false: Redox reactions do not contribute to the formation of free radicals?
False
True or false: A molecule with one or more unpaired electrons in its outer shell is called a free radical?
True
Free radicals are only formed from molecules via the cleavage of a radical to give another radical.
False
A molecule with one or more unpaired electrons in its outer shell is always considered a free radical.
False
Redox reactions do not contribute to the formation of free radicals.
False
True or false: Glycation is the process by which simple sugars bind to molecules such as proteins and lipids?
True
True or false: The predominance of advanced glycosylation end-products can result in abnormalities such as vascular fibrosis and reduced collagenous elasticity?
True
True or false: Glycation theory suggests that glucose may act as a mediator of aging?
True
