Summary Introduction
To differentiate: In the activity of troponin and tropomyosin in the contraction of muscles with the competitive inhibitor activity in the enzyme action.
Concept introduction: The contraction of muscle cells rely on the interactions between the thick and the thin filaments. The thick filaments are called as the myosin molecules, whereas the thin filaments are called as the actin filaments. The contraction of muscles is the result of filaments motion that is powered by a chemical energy.
The troponin complex and the tropomyosin are the regulatory proteins involved in the contraction of muscles. Competitive inhibition is a type of enzyme inhibition, where an inhibitor binds to the target molecule and prevents the binding of substrate to the enzyme.

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?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
