Question 12 of 25 What is motion?
A. The shortest path from start to finish, coupled with a direction
B. The measurement of the force of gravity acting on an object
C. A change in the position of an object with respect to a reference
point
O D. A transfer of energy from one object to another

C. A change in position of an object with respect to a reference point.

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.

the correct answer is 2 and 4
