People who can digest lactose, a disaccharide, have the ability to break it down into glucose and galactose, two monosaccharides. People who are lactose intolerant cannot properly break down lactose. Which of the following answer choices includes the proper terms to metabolically describe the process of digesting lactose?

Choose 1

(Choice A)
A
It is a catabolic process with an exergonic reaction that requires an input of energy.

(Choice B)
B
It is an anabolic process with an exergonic reaction that results in an output of energy.

(Choice C)
C
It is a catabolic process with an exergonic reaction that results in an output of energy.

(Choice D)
D
It is an anabolic process with an endergonic reaction that requires an input of energy.

really dont know just need some points

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.
