MCAT Biology Question — Tissues & Energy

Tissues specialized for long-term energy storage might have a large amount of:

 

a) capillaries

b) nuclear material

c) smooth ER

d) fat deposits

 

Explanation

Tissues specialized for long-term energy storage might have a large amount of fat deposits. Fat is a substance used for long-term energy storage. Capillaries would be found in large amounts near tissues with high metabolic activity like muscles. Large amounts of nuclear material are found in cells transcribing large amounts of RNA, such as plasma cells. Smooth ER is involved with detoxification, membrane phospholipid synthesis, and packaging of proteins. Smooth ER is not involved with long-term energy storage.

 

a) capillaries, incorrect, Capillaries are found in active tissues rather than energy storing tissues.

b) nuclear material, incorrect, Large amounts of nuclear material are found in cells actively transcribing.

c) smooth ER, incorrect, Smooth ER has little to do with energy storage.

d) fat deposits, correct.
