How does the structure of a protein affect the functions of muscle contraction

Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.

Explanation:

Fluctuations in the phosphorus cycle in aquatic ecosystems a. can lead to changes in the growth rates of aquatic populations The increase in phosporus amount in the aquatic ecosystem will increase the amount of algae within that ecosystem. When the amount of algae is increased, the aquatic organisms will have a LOT of food source which will increase the growth rate within their population.
