WILL MARK BRAINLIEST!!

write in your own words it doesn't need to be long!!

If we look at the drug OxyContin we can see that if someone has built a tolerance two things would occur their current dose would leave them feeling as if they need more and the tolerance could lead to abuse in order to get the pain relieving benefits. Withdrawal are the effects that happen when someone builds a tolerance. These symptoms could include dizziness, nausea, clammy skin, etc. The medication user might have built a tolerance and is feeling the effects of withdrawal because they need more of the medication for it to have an effect on their pain levels as well as reduce the withdrawal symptoms. Withdrawal is the bodies response to no longer having the medication consistently equal in the blood brain exchange.

Explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
