Which protein inhibits interaction between actin and myosin to prevent skeletal muscle contraction; and which ions remove the in

hibition?
Biology
1 answer:
zloy xaker [14]3 years ago
7 0

Answer:

Tropomysin, calcium

Explanation:

Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.

Muscle will only contract when they get a rush of calcium ions.

The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.

Large predators are found at higher trophic levels, what does this mean in terms of energy loss ?
VARVARA [1.3K]

Large predators are found at higher trophic levels because specialized bodies are needed to extract the small energy that gets to them.

The energy that gets to successive trophic levels decreases progressively because much of it is lost as heat. This means that a small percentage of the energy from the producers that form the bases of trophic levels to the predators that are somewhat at the top of trophic levels.

With big body size, the bodies of predators are organized into systems that work together to efficiently extract the small energy that gets to them from immediate lower trophic level.

More on the energy from trophic levels can be found here: brainly.com/question/13375401?
