Answer:

The correct answer is: Eccentric phase.

When talking about movement, we are talking about the activation of muscle fibers in order for this process to happen. In order for this to happen, motor neurons must activate the phases of muscle excitation, contraction and relaxation, so that the sarcomeres, and thus the fibers, can generate movement.

In essence, there are three stages, or phases, to complete muscle movement:   the concentric phase, which is when the muscle fibers are excited and begin the process of contraction. This means the muscle fibers will contract and generate movement, generating a shortening. Then we have the isometric stage, a moment in which there is no longer any more shortening of the muscle fibers, so basically, the movement is held and there is no further contraction, but neither is there relaxation of the muscle fibers. Finally, we have the eccentric phase. This phase is characterized precisely because it is the moment when the muscles begin to return to their resting position.

Should existing structures build from CCA-treated wood be removed?
stiks02 [169]
<span>Chromated copper arsenate, or CCA, is a pesticide that has been used for years in pressure-treating lumber to prevent destruction from rot and insects. Arsenic, a toxic chemical, can leach from this treated wood, leaving residues on the wood’s surface and in nearby soil. Young children who play on or near decks or playscapes made from CCA- treated wood can get arsenic on their skin and into their bodies, especially if they eat or drink without washing their hands. Because of the health risks of long-term exposure to arsenic, the Environmental Protection Agency (EPA) has announced that as of December 31, 2003, arsenic Currently the EPA does not recommend that people remove existing structures made with CCA-treated wood or the soil surrounding those structures. However, they do recommend that people reduce their potential exposure to arsenic.</span>

sp2606 [1]

Answer: see explanation

Explanation:

A. substrate

B. Active site

C. Enzyme binds with substrate

D. Active site of enzyme

E. Products leaving active site

Simplified enzymatic reaction. The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP). The bound products are released, returning the enzyme to its unbound form, ready to catalyze another round of converting substrate to product.
