Which of the following is an organic molecule?

C. Sucrose

Explanation:

Sucrose is a carbohydrate formed from Glucose and fructose making it a dissacharide. It consists of Hydrogen, Oxygen and Carbon.

Answer : The correct option is, (C) Sucrose.

Explanation :

Organic molecule : It is defined as the molecule that is made up of carbon atoms and other atoms like hydrogen, oxygen and nitrogen are attached to it and carbon atoms can be present in the rings or long chains.

Organic molecule usually found in living systems.

From the given options, we conclude that the option C (sucrose) is an organic molecule because it is a disaccharide which is composed of two monosaccharide (glucose and fructose).

The chemical formula of sucrose is,

Hence, the organic molecule is, sucrose.

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.
