Which of the following generalizations explains how anabolic steroids can affect muscle growth?
A) Anabolic steroids increase the level of testosterone, a hormone predominately found in males.
B) Anabolic steroids easily pass through the membrane and bind steroid receptors which migrate to the nucleus and function as a transcription factor.
C) Anabolic steroids are water soluble and can transport to the muscle tissue readily.
D) Anabolic steroids alter the phosphoinositide pathway, thereby increasing levels of calcium in the cytosol and subsequently increase the strength of muscle contraction.
E) None of the above is correct.
Answer: B) Anabolic steroids easily pass through the membrane and bind steroid receptors which migrate to the nucleus and function as a transcription factor.
