Absorption and assimilation — practice question

This graph illustrates the way blood alcohol concentration varies after a person has drunk alcohol.
(a)[4]

Suggest how the graph’s pattern can be accounted for by processes occurring in different parts of the body after alcohol has been drunk.

(b)[2]

The graph indicates that this person’s maximum blood alcohol concentration after drinking alcohol is $0.75\,\text{g per dm}^3$. Suggest two reasons why the maximum blood alcohol concentration might not be the same for two people after they drink the same volume of alcohol.

(c)[3]

Describe the short-term effects that a high blood alcohol concentration can cause.
