Multiple choice

Consider the following statements: (a) Acrosome facilitates fertilization by rupturing vitelline membrane as it contains hyalourinidase enzymes, which helps the sperm to penetrate into the ovum. (b) Leydig cells are found in the connective tissue around the seminiferous tubules of testes. They secrete testosterone into the blood. (c) Epididymis is a convoluted tube that leads into vas deferens. Which of the above statements is / are incorrect?

  1. Only (a) and (c)

  2. Only (a) and (c)

  3. Only (a) and (c)

Statement (a) is correct. Acrosome facilitates fertilization by rupturing vitelline membrane as it contains hyalourinidase enzymes, which help the sperm to penetrate into the ovum. Statement (b) is correct. Leydig cells are found in the connective tissue around the seminiferous tubules of testes. They secrete testosterone into the blood. Statement (c) is correct. Epididymis is a convoluted tube that leads into vas deferens. In the epididymis, the sperms are temporarily stored so that they become motile. All are correct.
