The firing frequency of Group 1 muscle spindle afferents is highest during a change of muscle length, and the firing frequency of Group 2 muscle spindle afferents is highest when the muscle is longer. b. Golgi tendon organ afferent firing frequency increases when tension on the muscle increases. c. Muscle spindle reflex is an example of negative feedback; afferent sensory neuron detects stretch and the result is an efferent motor neuron activation that results in contraction. d. both a) and b) are correct, and c) is incorrect e. a), b) and c) are all correct

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.
