Question

question 39 (1 point) which of the following explains why loss of lean tissue occurs as people grow older? increase in metabolism decrease in sarcopenia increase in lactic acid production decrease in metabolism increase in plaque buildup around the artery

Explanation:

As people age, metabolism decreases. A decrease in metabolism leads to less energy - consuming activities in the body, which can contribute to the loss of lean tissue. An increase in metabolism would generally be associated with more energy - using processes and not tissue loss. Sarcopenia actually increases with age, not decreases. Lactic acid production is more related to short - term anaerobic exercise rather than age - related lean tissue loss. Plaque buildup around the artery is related to cardiovascular health and not directly to lean tissue loss.

Answer:

Decrease in metabolism
