These subcellular structures are responsible for catabolism of ethanol.

Mitochondria

Explanation:

The first step of the alcohol metabolism takes place in the cytosol of the cell where the enzyme alcohol dehydrogenase starts to act.

The alcohol here is converted into the acetaldehyde. The acetylaldehyde is metabolized mainly by the alcohol dehydrogenase 2 in the mitochondria to form acetate.

It releases NADH and ROS species which is neutalized by the antioxidants in the human body.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
