Summary Introduction

To explain: The reason why diet deficient in zinc does not reduce the number of red blood cells, but it impairs respiratory function by reducing CO2 output.

Concept introduction: The mineral zinc activates the enzymes of protein metabolism. It is a part of carbonate dehydratase and carbon dioxide transfer. It is important for the immune functions. Most carbonic anhydrase contains zinc ion in their functional site, and they are therefore classified as metalloenzymes.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
