which of the following target organs/systems is affected by the sympathetic nervous system but is not affected by the parasympathetic nervous system?
○ cellular metabolism
○ lungs
○ gallbladder
○ salivary glands

Explanation:

To solve this, we analyze each option:

• Lungs: Both sympathetic (bronchodilation) and parasympathetic (bronchoconstriction) affect them. Eliminate.
• Gallbladder: Parasympathetic stimulates gallbladder contraction, sympathetic may inhibit. So parasympathetic affects it. Eliminate.
• Salivary glands: Both systems affect salivary secretion (sympathetic: thick secretion; parasympathetic: watery). Eliminate.
• Cellular metabolism: The sympathetic nervous system increases cellular metabolism (e.g., glycogen breakdown, lipolysis), while the parasympathetic nervous system does not have a direct effect on cellular metabolism.

Answer:

A. cellular metabolism
