Relaxin
<span>Relaxin, secreted by the corpus luteum of the ovary as well as the placenta, is responsible for helping to inhibit uterine activity and to soften the cervix and the collagen in joints. Softening of the cervix allows for dilatation at birth; softening of collagen allows for laxness in the lower spine and so helps enlarge the birth canal. The effect of estrogen is to cause breast and uterine enlargement. Progesterone has a major role in maintaining the endometrium, inhibiting uterine contractility, and aiding in the development of the breasts for lactation. Human placental lactogen (hPL), also known as human chorionic somatomammotropin, serves as an antagonist to insulin, making insulin less effective, thereby allowing more glucose to become available for fetal growth.</span>
Answer:
It depends whether you're talking about catabolism or anabolism. If you're creating new organic compounds, then it's an anabolic reaction. That way, ATP will be broken down, so as to fuel the chemical reactions. However, if you are talking about catabolic reactions, in which you aim to obtain ATP, by means of degradation of certain substances, in that case the right answer would be II.
Explanation:
Cells in an organism can develop in different ways to perform different tasks.
Answer:
citric acid cycle
Explanation:
To give just one example, acetyl CoA (mentioned above) that's produced in cellular respiration can be diverted from the citric acid cycle and used to build the lipid cholesterol. Cholesterol forms the backbone of the steroid hormones in our bodies, such as testosterone and estrogens.
The mainstay of treatment for testicular cancer is chemotherapy. This is to eradicate malignant cells in the testicle. As a consequence, the patient can be sterile as the chemotherapy also attacks healthy living sperm. Since the patient wants to build a family, he should store his sperm and get it preserved by cryopreservation before the treatment is started.
