Question

During cleavage, oxygen consumption is

• A. Low
• B. High
• C. No effect on the rate of oxygen consumption
• D. Oxygen consumption decreases than usual requirement

Answer 1

Answer: (B)

High

Cleavage is the term used for repeated mitotic divisions that take place during the growth of an embryo. Cleavage is basically the process of division of a single-celled zygote into a multicellular blastocyst that further undergoes implantation and development to form a fetus. As the rate of DNA synthesis is very high during cleavage, the oxygen consumption is also very high.

So, the correct answer is 'High'.
