Mariana eats an orange. Which statement describes the ultimate source of the energy that her body receives when she digests the orange?
A. Organic matter, rich soil in which the orange tree grows, and adequate water all work together to generate the energy that can be
obtained from the orange.
B. The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
C. The orange tree obtains energy from the nitrogen and other compounds in fertilizer.
D. The orange contains the energy-rich nutrients that it draws from the soil.

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.

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
