Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.
The process of cellular respiration catabolic pathway that breaks molecules into energy
<u>Explanation:</u>
Metabolic pathways consist of two distinct types: catabolic and anabolic. Catabolic deliver energy while breaking down molecules into easier molecules. Cellular respiration is one case of a catabolic pathway. During cellular respiration, sugar is held in by the cell and break to discharge energy that enables us to live.
Cellular respiration is the manner of oxidizing food particles, similar glucose, to carbon dioxide and water. The method transpires in two states:
- glycolysis, the division of glucose to pyruvic acid
- the entire oxidation of pyruvic acid to carbon dioxide and water
