Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because...genes dictate the production of specific enzymes, and affected individuals have genetic defects that cause them to lack certain enzymes.
Explanation:
Archibald Garrod researched on alkaptonuria and proposed the ‘one gene-one enzyme’ hypothesis. This led to the finding that alkaptonuria is caused due to an inherited or “inborn error of metabolism”.
This hypothesis stated that each gene codes and responsible for a single specific enzyme which facilitates a particular step in the metabolic processes.
According to Garrod, a mutation of a particular gene leads to specific error or defect leading to a lack of a particular enzyme that takes part in the biochemical metabolic pathways. This disrupts the metabolic pathway at the specific enzymatic action point.
In alkaptonuria, it was found that the defective phenotype of dark urine is due to the inborn error happening during the waste elimination process.
Depressants slow (depress) the nervous system which slows the brain and body reactions
Answer:
D) Tobacco
Explanation:
While tobacco can have a few medical uses, it has the least amount and many don't even consider those uses to be relevent whatsoever.
"Fentanyl, also spelled fentanil, is an opioid used as a pain medication and together with other medications for anesthesia. "
Advil: Generic drug name: Ibuprofen. Ibuprofen is used to relieve pain from various conditions such as headache, dental pain, menstrual cramps, muscle aches, or arthritis. It is also used to reduce fever and to relieve minor aches and pain due to the common cold or flu."
" Tylenol (acetaminophen) is a pain reliever and a fever reducer. Tylenol is used to treat many conditions such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers."
D) Would seem the best option! Hope this helped! :)
Honestly, I'm not positive myself. All I can say is that overworking your joints without enough cool-down time will put you at high risk for arthritis.
