The process occurring in the liver rids the bloodstream of 90% of the alcohol present and is a constant process.

The following options are attached to the above question:

A. Metabolism

B. Absorption

C. Oxidation

D. Excretion

ANSWER

The correct option is C.

Biological oxidation of alcohol is the process by which the liver handles the presence of alcohol in the body system. The liver is responsible for metabolizing the alcohol that are present in the body. The metabolism of alcohol occurs in two steps; the first step is the oxidation of alcohol to ethanal or acetaldehyde. This product is very toxic to the human body and is majorly responsible for the symptoms of hangover that drinkers usually experience. The liver oxidises ethanal to acetic acid as quickly as possible in order to prevent damage to the body system.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
